LM76

E. Longmeadow, MA Motion — Control Components – Linear Motion – LM76 now offers one piece ETX Linear Bearing/Pillow Blocks that will not degrade in a radioactive environment! Machined from a solid block of self lubricating ETX, linear bearing-blocks have high strength, excellent wear resistance, low coefficient of friction, and excellent dimensional stability at higher temperatures As there is no other materials such as PTFE seals or lubricants these bearing-blocks are maintenance free. Custom designed for use in a nuclear power plant these linear bearing/pillow blocks travel on ceramic coated shafting (also supplied by LM76) completely submerged in radioactive water. Designed with a slight interference fit between bearing ID and shaft, contaminates are scraped from the shaft’s surface. The low frictional characteristics of ETX have little impact on drive force. They are now available in Inch and Metric sizes.

ETX bearing-blocks are also FDA/USDA/3-A Dairy compliant and are also are ideal for: Pharmaceutical, medical, food, and dairy processing applications.

EXT features a high continuous service temperatures up to 210°F (100°C) and offers good chemical and abrasion resistance, low moisture absorption, and resistance to staining. These ETX linear bearing-blocks with the slight interference fit keeps the bearing free from debris and bacterial contamination, are not affected by biological fluids, mild acids, can be washed down with cleaning agents, and steam cleaned.

Don’t need solid EXT bearing-blocks consider the FDA/USDA/3-A Dairy compliant electroless nickel coated or stainless steel pillow blocks with PTFE linear bearings and Snap-in EXT Scraper Seals which are available for closed linear bearings, and closed pillow and flange blocks.

LM76 also manufacturers a broad variety of FDA & USDA compliant bearings and shafting, in inch sizes of .25 inches to 1.5 inches, and a FDA & USDA compliant profile rail and slide system that can easily be integrated into new and existing applications. The bearing options include: Self-lubricating FDA & USDA compliant Teflon® composite bearings in a 304 stainless steel shell, and lower cost bearings with a ceramic coated shell and FDA & USDA compliant liner. Bearings are available in closed and open configurations, and are drop-in replacements for all inch sized linear ball bearings.

Equipment Solutions

Forestville, CA –The motion control LFA-3404 Linear Focus Actuator is a high performance compact positioning system.  It was specifically developed for optical applications requiring both high precision and high-speed positioning over a short to medium stroke.  The motion control LFA-3404 is well suited for optical focusing and other micropositioning applications such as scanning interferometry, surface structure analysis, disk drive testing, autofocus systems, confocal microscopy, bio-technology, semiconductor test equipment.  Note that this motor is normally configured with an analog position feedback sensor and can be optionally equipped with a digital quadrature feedback element.   

The key to this products immense success is its novel tubular architecture.  This arrangement provides a means to send the optical path directly through the middle of the motor.  The moving optic attached to the motors ‘C-mount’ is not cantilevered and so has no torques. By design, the LFA-3404 Linear Focus Actuator rotates approximately 0.1 degrees or 1.7 milliradians for every 1 millimeter of translation.  Product manufacturing tolerances are closely monitored so that both lateral and angular displacements about the motion axis are as small as possible.

Motion Control Servo2Go-Logo

Motion Control Components – Servo2Go.com announces the release of the DZRALTE Series of High Performance Digital Servo Drives from Advanced Motion Controls of Camarillo, CA, which are engineered to conquer the most demanding industrial applications!

The DZRALTE Series are motion control digital servo drives that control brushed & brushless servomotors in a compact form factor which make them ideal for embedded applications. These fully digital drives operate in torque, velocity, or position mode and employ Space Vector Modulation (SVM) which results in higher bus voltage utilization and reduced heat dissipation compared to traditional PWM drives. The command source can be generated internally or can be supplied externally. In addition to motor control, these drives feature dedicated and programmable digital and analog inputs and outputs to enhance interfacing with external controllers and devices.

The DZRALTE Series feature a RS-232 interface for drive configuration and setup as well as a RS-485 interface for drive networking. All drive and motor parameters are stored in non-volatile memory. Drive commissioning is accomplished using AMC’s powerful & user friendly free DriveWare software.

The combination of a DigiFlex® Performance™ DZRALTE servo drive with its DriveWare software establishes a new benchmark in versatility!

Motion Control Capabilities built into the DZRALTE servo drives include:

  • Size Ranges: 10-175 VDC @ 6A to 30A continuous (60A peak) Output
  • Full tuning control of all three servo loops: Position, Velocity and Torque!
  • Real-time oscilloscope with up to 8 channels to ensure that tuning achieves the highest performance
  • Status window with over 50 simultaneous channels for drive and system diagnostics
  • I/O configuration configurable to latch/non-latch as well as active-high & active-low
  • Universal servo motor compatibility by means of automatic commutation adjustment
  • Dual Loop Feedback – Increases both stability and accuracy
