Timken GRAE20RRB-COL Spherical Insert Bearing

The Timken GRAE20RRB+COL insert ball bearing is a wide inner ring unit with an eccentric locking collar that provides secure shaft retention in mounted-bearing housings subject to moderate radial loads. It features a spherical outside diameter for self-alignment within compatible housings, double contact seals to keep lubricant in and contaminants out, and is relubricatable with bearing-steel construction for durability. Key specs include a 20 mm bore, 47 mm outside diameter, inner-ring width 21.44 mm, bearing width B1 31 mm, outer-ring width 14 mm, and an internal clearance of C3; weight is about 0.29 lb (0.13 kg). The locking collar uses two set screws (M6 x 1) for secure shaft locking. Dynamic radial load rating is 3,190 lbf (14,200 N) and static radial load rating is 1,460 lbf (6,500 N). Typical applications include conveyors, agricultural machinery, packaging equipment, material handling systems, fans, and other industrial rotating equipment. Common replacements include SKF YET204 insert bearing, INA GRAE20-XL-NPP-B insert bearing, and NTN AEL204 series insert bearings.
