Scraper seals for linear bearings used in food processing applications

A range of FDA/USDA/3-A diary compliant seals have been introduced by LM76, the snap-in ETX Scraper Seals. Machined from Ertalyte PET-P, ETX Scraper Seals have high strength, 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 suitable for; pharmaceutical, medical, food, and dairy processing applications.

EXT Scraper Seals feature high continuous service temperatures up to 100°C (210°F) 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.  

LM76 also manufactures a broad variety of FDA and USDA compliant bearings and shafting, in sizes of 0.25-1.5”, and a FDA and USDA compliant profile rail and slide system that can easily be integrated into new and existing applications.

The bearing options include; self-lubricating FDA and USDA compliant Teflon composite bearings in a 304 stainless steel shell, and lower cost bearings with a ceramic coated shell and FDA and USDA compliant liner. 

Bearings are available in closed and open configurations, and are drop-in replacements for all inch sized linear ball bearings.
