How Would You Position Components Of An Experimental Reactor Vessel Weighing 33 Tons?
Motion Control – Linear Motion Application
Easily … … Using Custom made LM76 Jet Rail Bearings and Shafting!
When a privately funded research company was ready to move from their original Proof of Concept to a sustainable fusion reactor to produce clean sustainable energy, they realized that extremely heavy components would need to be assembled and disassembled and reassembled again for design modifications and maintenance. The completed assembly would be the length of two buses and easy alignment of the individual components would be critical.
The main reactor, the fusion containment chamber that is capable of containing a plasma medium of 10 to 15 million degrees is made of non-magnetic stainless steel as are many of the components. The Plasma Medium could be described as a football shaped blob about 1 meter in diameter by 2 meters long. The plasma medium is injected from each end of the reactor assembly by Plasma Guns.
Motion Control -What To Consider When Specifying A Linear Slide
Motion Control – Tutorial
Considerations when specifying a linear slide for a new or existing application.
By Mike Quinn • LM76
When a design engineer has fully defined a linear-motion application’s requirements regarding travel length, speed, force, and accuracy as well as repeatability, the next question to answer is this:
Does an off-the-shelf linear slide (or a stock linear slide from a catalog) fully satisfy the application?
Off-the-shelf linear slides are advantageous for their quick delivery and lower cost than that of custom components. No wonder most linear-motion designs do in fact employ off-the-shelf linear slides from various component and system suppliers.
The Engineering Edge – What’s the Difference?

Motion Control – The Engineering Edge – Linear Motion Application – Moving Articles of Antiquity!
Motion Control – Linear Bearings Application
Linear Motion Application – How Do You Move Articles of Antiquity?
Very Carefully With A High Load Rail System from LM76!
E. Longmeadow, MA – — The Boston Museum of Fine Arts (MFA) has to move articles of antiquity from one location to another. In this instance, they are moving a 5000 year old relief (hieroglyphics) weighing 8000 pounds to a new location in the Museum. Here is a frontal photo of the Relief from The Tomb of Senenuka.
Part of wall from tomb of Senenuka; nine stones fitting together and including two niches; lower left piece smooth limestone; upper far left preliminary black ink sketch; right of this sketch is a complete relief showing two seated figures; central piece has large scene of seated male on the left and other smaller male figure to the right; upper far right male figure relief outline; left of this again a scene of two seated figures at a table.
Senenuka Time of Khufu or Khafre (Maybe Dyn 5?) Overseer of the Pyramid-town of Khufu, Director of King’s wad-priests, Boundary official of a settlement, etc.
The MFA contracted CBI Consulting of Boston to design the frame and fixturing. Craig Barnes, an award winning architectural engineer called Mike Quinn of LM76 to review the linear motion application. Over the course of several weeks, LM76 and design partner Todd Kanipe designed a telescoping, high load roller/linear motion rail system that won approval. According to CBI’s Keith Bouchard, the linear rail system moves very smoothly and so far meets the expectations of this program.”
Linear Motion Application – According to MFA Antiquity Specialist Jean Louis Lachevere, “All of these moves present very real dangers to the artifact being transported. In this case, we have a 8000 pound relief which already has its problems due to age and the fact that it is limestone ( limestone is very vulnerable to the atmosphere ).” Seen from the front, the relief is straight. From the back, much of the top back is gone. Thus, the back of the relief has to be plastered so the back is flat. Pins are inserted to further reinforce the relief and then it is tipped on its back. It is then moved to its new atmospherically controlled display case. LM76’s design is used in the transfer from the dolly to the mounting rails and restraints in the display case. This 36” motion is fraught with things that can go wrong. One of the considerations is the possibility of an earthquake…any problem conceivable is taken into account.
Castors and sliders at end of armature. The sliders are mounted to the castors and work like telescoping drawer slides.
Castors and sliders as seen from below. The chalk X is used to mark the block where added weld is required. Each block is to be welded both sides. Each slider is to be addressed.
Photo demonstrates that the wheels can rotate independently.

Motion Control – Use FDA Compliant Off-the-Shelf Linear Motion Components!
Motion Control – FDA Compliant Components
To: OEMs “Tooling Up” for Urgently Needed Medical Products! Use FDA Compliant Off-the-Shelf Linear Motion Components!
 |
E. Longmeadow, MA — Motion Control Components – Linear Motion – In dealing with the COVID-19 pandemic many companies have volunteered or been requested to produce urgently needed medical products such as: Masks, gowns, and ventilators. “Tooling Up” quickly to produce medical grade products for some companies can bring challenges. In addition to needing FDA compliant materials that will be used in the actual masks, gowns, and ventilators, the tooling used to manufacture these products may also need to meet FDA compliance standards. Depending on the product being manufactured, the tooling may need to be: Washed down using caustic chemicals, cleaned with high pressure steam, or sterilized with high Intensity Ultra Violet light or radiation.
Ordering custom FDA compliant linear motion slides and XYZ stages can result in long delays. As an alternative, many companies have linear motion slides in stock for immediate delivery, however, they may not be FDA compliant. In many cases it is the bearings that are not in compliance. LM76 manufactures several types of FDA compliant linear bearings and pillow blocks that are drop-in-replacements for existing bearings. FDA compliant bearings and pillow blocks from LM76 will not trap contaminating debris and can be thoroughly sanitized following Sanitation StandardOperating Procedures (SSOPs). SSOPs are detailed schedules and procedures specifying what to clean, how to clean, how often to clean, and the record keeping used for monitoring.
A helpful component selection guide from LM76, “Linear Bearings, 6 Simple Steps – FDA Compliance, Wash Down Compliance,” details the linear motion components available from LM76 that are FDA/UDSA/3A-Dairy compliant. Included are: Foodstream electroless nickel plated pillow blocks, PTFE lined stainless steel bearings, ceramic coated linear bearings, self-aligning corrosion resistant linear ball bearings, and Thomson® Super SmartTM corrosion resistant, self-aligning, high load linear ball bearings, and solid ETX pillow block/bearings. Shafting to compliment the type of bearing selected includes: Class L Stainless 303/304/316, 440C case hardened stainless, Rc 60 case hardened steel with an Armoloy coating and also Rc78 Class L for enhanced hardness and wear resistance. End blocks and shaft supports that have a ceramic or electroless nickel coating are also available, as well as new ETX Scraper Seals that prevents intrusion of contaminates adding another line of defense.
LM76 also designs and custom builds linear slides from Stainless Steel and other FDA wash down compliant materials.

Motion Control – CERAMICSPEED Bearing Units Are FDA Compliant!
Motion Control – Ceramic Radial Bearings are FDA Compliant
E. Longmeadow, MA – LM76 is continuing to expand its FDA compliant radial and linear bearing product lines. CERAMICSPEED Bearing Units are the latest additions. Bearings used in the food and beverage industry have to be reliable, easily cleaned, and require only minimal maintenance. CERAMICSPEED Bearing Units featuring FDA-approved Si3N4 (Silicon Nitride) balls have extremely long service life as Si3N4 balls are 2 times harder than steel balls and 4 times smoother. This means, CERAMICSPEED Bearing Units handle higher loads with less friction, resulting in longer life of the balls and the race. Balls made from Silicon Nitride do not change their shape under load and are not subject to spalling which can contaminate the foods or beverages being processed. They are also very tolerant of temperature extremes (-30OC to 100OC) and thermal shock.
CERAMICSPEED Bearing Units have also been designed with rounded surfaces and are then covered with polyurethane to create an smooth impenetrable surface where debris, bacteria, water and other liquids cannot collect. Available in standard styles and sizes, these low maintenance bearings are shipped lubricated with and FDA approved grease or with a proprietary SLT lubricant created to be extremely durable and maintenance free for extremely harsh environments.

Pegasus Series 1 Linear Bearings – For When A Linear Bearing Simply Cannot Fail!
|
E. Longmeadow, MA Motion — Control Components – Linear Motion – LM76 has developed the most corrosion resistant linear bearing available. In space, deep under the sea, or in the harshest environments when there can be no “Plan B,” Pegasus Series 1 Linear Ball Bearings can be counted on to perform. In some applications linear bearings will not move for days, weeks, months or even years, however, when called on to perform they must work as if they just came out of the box. LM76’s Pegasus Series 1 Linear Bearings feature Silicon Nitride (SiNi) Ceramic Balls in a shell with retainer and end caps all made from 440 Stainless Steel and then ArmorloyTM coated.
Silicon Nitride was selected for the balls because it is: 40% lighter than steel, inert to chemicals (vapors, sea water, caustic washing and sterilizing solutions), capable of higher speeds and higher loads: (RC78 hardness), FDA compliant (used in surgical instruments), and does not corrode or support electrolysis.
The shell, bearing retainer and end caps are made from 440 Stainless Steel and coated with Armoloy TDCTM(Thin Dense Chrome). Armoloy is a hard (78Rc), coating with a micro-nodular surface texture. The coating’s nodular finish reduces the amount of surface area in contact with the SiNi balls reducing friction and extending life.
Pegasus Linear Bearings are available 2 series (closed and open), and in 4 sizes (1.000″, 1.250″, 1.500″ and 2.000″). Dynamic load rating for these bearings are: 1.000″ 220 lbs, 1.250″ 352 lbs, 1.500″ 490 lbs, and 2.000″ 858 lbs. Bearings are designed for zero clearance on Class L linear shafting. For maximum performance we recommend LM76 Case Hardened 440 Stainless Steel shafting with ArmorloyTM coating.

Application Story – FDA/Washdown System Excels with Special Linear Motion Shaft Assembly from LM76!
|
E. Longmeadow, MA – — Linear Motion – Application Story – Dairy machinery manufacturers are under intense scrutiny by FDA inspectors when it comes to FDA material and caustic washdown compliance. Recently, LM76 was called by a large US dairy packaging company to review a problematic portion of their filling line. After each shift, the filling line is washed-down, has a caustic foaming agent applied to kill bacteria and then is final rinsed. The caustic foaming agent was destroying – literally eating – the aluminum shaft supports while shafting exhibited pitting and showed signs of minor corrosion. Additionally, there were areas where product got trapped and these locations were havens for bacterial growth. Because this system was in-place and our customer was the end-user, LM76 engineers had to use direct drop-in replacement com¬ponents. What to do?
First, we decided to forgo the original bearing system that used 440c stainless linear ball bearings running on 440c hardened shafting. After reviewing loads and speeds we determined that our stainless FDA Compliant, self-lubricating linear bearings would do the job. By choosing sliding friction bearings, we were able to switch the less corrosion resistant 440c with a better 316 stainless shafting while eliminating greasing of the linear ball bearings. To increase shaft hardness, corrosion resistance and decrease “Stick/Slip” of the sliding bearings, we applied an Armoloy coating. This coating raises the shaft hardness from Rb25 to Rc78. Additionally, both the 316 stainless and the coating are FDA compliant. Along with enhanced hardness, corrosion resistance and FDA compliance, this coating has an inherent lubricity that aids in lowering “Stick/Slip”. “Stick/Slip” is a condition inherent in sliding linear bear¬ings. It takes a greater force to move a sleeve bearing linear system from static position than it does to maintain dynamic motion. Thus any assistance in lowering this value is meaningful. Now that we had the correct shafting, we turned our attention to the aluminum shaft support Here we made 2 design decisions:
1. We applied a ceramic coating to the aluminum “T” support. This coating is FDA compliant, is file hard (resists scratching) and is highly corrosion resistant.
2. To enhance system flushing to remove trapped product that could produce harmful bacteria, we segmented the support system to allow for proper evacuation of all washdown solutions and debris.
