Timken GRAE20RRB Self Aligning Insert Bearing

Description:

The Timken GRAE20RRB is a wide inner ring insert ball bearing with an eccentric locking collar, engineered to provide reliable 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 premium bearing steel and incorporates double contact seals to retain lubricant and protect against contaminants. The eccentric locking collar provides secure shaft locking for dependable performance in normal shaft rotation applications. It is widely used in conveyors, agricultural equipment, packaging machinery, material handling systems, fans, and general industrial machinery. Maintenance teams, OEMs, and system integrators specify the GRAE20RRB for equipment replacement, retrofit projects, expansion, and preventive maintenance to improve equipment reliability and reduce downtime.

Applications:

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