LM76, East Longmeadow, Mass., introduced redesigned lubricating stainless-steel and self-aligning linear ball bearings in pillow block and flange block options.
The new design features a lubrication fitting and an alignment set screw in the pillow blocks and flange blocks, where lubricants can then be pumped directly inside of linear ball bearing races without having to remove the bearing from the shaft. The pillow and flange blocks have also been designed to accommodate an encapsulated ETX Scraper Seals that prevents contaminants from getting inside the bearing, yet still retaining the lubricant in the bearing.
The newly designed pillow blocks are available in closed single and double bearing models for inch-sized shafts from 0.5 inches up to 2 inches, and the flange blocks are available in single and double bearing models for inch-sized shafts from 0.5 inches to 1.25 inches. The pillow blocks come in untreated aluminum or with a FDA-, USDA- and 3A-Dairy compliant, corrosion-resistant electroless nickel coating.
The pillow block and flange block bearing combinations are ideal for food processing, handling, packing and bottling and other applications where corrosive or contaminating fluids (e.g. fruit juices) exist.
