All Brewton Pillow Blocks have machined bases and bearing ends. They are tapped for grease fittings and provided with grease grooves to lubricate the full bearing surface. All housings are ATSM A48 Class 35 Grey Iron. Split blocks are furnished with shims for adjustment and the bearing edges, at the split, are beveled so that the lubricant is not scraped off the shaft. Brewton Pillow Blocks can be supplied with a variety of liners which include Babbitt, Bronze, Phenolic and UHMW.
