Philadelphia, PA, — Motion Control Components and Systems – The ACR-32UT precision rotation stage is a low profile rotary table with a high-speed direct-drive rotary servo motor. The 32 mm center aperture and lightweight construction makes this rotary stage an ideal choice for handling 300 mm silicon wafers for semiconductor processing

ACR-32UT has a very wide dynamic speed range and can move at sub-rpm speed with low velocity ripple and can accelerate quickly to 1,500 rpm. This stage can be easily installed into IntelLiDrives low profile open frame XY tables with a minimal stack-up height to minimize Abbe error.

These features make the ACR-32UT outperform the stability, acceleration and settling speed of traditional servo motor gear-driven mechanisms, according to the company. IntelLiDrives offers a wide range of servo amplifiers and advanced controllers to provide a complete, integrated package.

Motion Control – Steinmeyer Introduces Precision Ball Screws Featuring Xi-Plus Technology!

Motion Control - Steinmeyer Xi-Plus Ball Screws

Steinmeyer Logo


BURLINGTON, MA –Motion Control Components – Ball Screw Technology – Steinmeyer now offers 16mm to 80 mm Ballscrews that feature Xi-Plus Technology Optimized spindle surfaces.

Motion Control - Steinmeyer Xi-Plus Ball Screw Technology

At Steinmeyer you obtain ball screws with connecting dimensions according to DIN 690651 or ISO 3408.

Any size can be selected among available nut flange shapes (round, single, flattened, flattened on both sides) and different load capacities.

And now you have the option to receive Steinmeyer ball screws in Xi-Plus technology with optimized spindle surfaces for better running features.


Standard Ball Screws:

Microscopic irregularities on the raceway surface of the spindle can cause vibrations, irregular running characteristics, and noise in machines.

Xi-Plus technology Ball Screws:

Through the use of innovative production technologies, the roughness of the spindle surface can be reduced and therefore performance is optimized. Irregular running characteristics are virtually eliminated.

Motion Control – FDA/USDA/3A-Dairy Compliant ETX Scraper Seals for Linear Bearings Used In Food Processing Applications!

Linear Motion Control Components - LM76 ETX-Seals!


E. Longmeadow, MA — Motion Control — Linear Motion – LM76 has introduced FDA/USDA/3-A Dairy compliant, snap-in ETX Scraper Seals for linear bearings. Machined from Ertalyte® PET-P, ETX Scraper Seals have high strength, excellent wear resistance, low coefficient of friction, and excellent dimensional stability at higher temperatures than seals from other materials. Designed with a slight interference fit between bearing ID and shaft, ETX Scraper Seals prevents contaminates and debris from migrating beneath the seal as it scrapes the shaft surface. Ertalyte® PET-P’s low frictional characteristics have little impact on drive force. These FDA/USDA/3-A Dairy compliant scraper seals are ideal for: Pharmaceutical, medical, food, and dairy processing applications.

EXT Scraper Seals feature a high continuous service temperature up to 210°F (100°C) and offer good chemical and abrasion resistance, low moisture absorption, and resistance to staining. These linear bearing scraper seals keep bearings free from debris and bacterial contamination, are not affected by biological fluids, mild acids, can be washed down with cleaning agents, and steam cleaned. Snap-in EXT Scraper Seals are available for closed linear bearings, and closed pillow and flange blocks.

Linear Motion Components - LM76 ETX-Scraper Seals!

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.

About LM76

Founded in 1976, LM76 has been a leading designer/manufacturer of linear bearings, slides and linear motion systems. LM76 is renowned for its industry leading Minuteman PTFE Composite linear bearings. LM76 is a leading supplier of precision linear shafting: RC60, 300 Series Stainless Steel, and ceramic-coated aluminum shafting.
