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 are 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, contaminants 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 suitable for Pharmaceutical, medical, food, and dairy processing applications.
EXT features 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-in. to 1.5-in., and an 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.
