Timken GRAE20RRB-COL Spherical Insert Bearing

Description:

The Timken GRAE20RRB+COL is a wide inner ring insert ball bearing with an eccentric locking collar, designed to provide dependable shaft support in mounted bearing applications operating under moderate radial loads. Featuring a spherical outside diameter for self-alignment within compatible housings, this relubricatable insert bearing is manufactured from high-quality bearing steel and incorporates double contact seals to protect against contamination while retaining lubricant. The included eccentric locking collar ensures secure shaft locking and dependable performance in normal shaft rotation applications. It is widely used in conveyors, agricultural machinery, packaging equipment, material handling systems, fans, and general industrial machinery. Maintenance teams, OEMs, and system integrators specify this insert bearing for equipment replacement, retrofit projects, expansion, and preventive maintenance to improve equipment reliability and minimize downtime.

Applications:

The Timken GRAE20RRB+COL insert ball bearing is engineered for mounted bearing housings requiring self-aligning capability and secure shaft retention. Its eccentric locking collar provides positive locking to the shaft, while the spherical outer diameter accommodates minor shaft misalignment for smooth operation. Typical applications include conveyors, food processing equipment, agricultural machinery, packaging systems, textile machinery, fans, and industrial material handling equipment.
