Made from 52100 series bearing steel, the CSB insert has a cylindrical OD for mounting in equipment housings or stamped steel cylindrical bearing housings. The CSB insert bearing has a flush back face which makes it ideal for positions where space is limited. It features a metal-faced rubber contact seal which keeps lubricant in while keeping contaminants out. The seal is crimped in place on the entire circumference of the outer ring.
Because this style insert is commonly used in pressed steel housings without grease fittings, CSB insert bearings come standard as a non-greaseable insert and are considered to be Lubed-for-Life.
Factory Lubrication
The CSB Cylindrical OD Normal Duty Narrow Inner Ring Set Screw Insert Bearing is factory lubricated with Chevron SRI#2 AW (anti-wear) grease. The insert contains 30-40% grease fill by volume. The CSB insert is factory sealed after lubrication and is considered Lubed-for Life.
