The Timken Company GRA111RRB-C0L Ball Bearing

Description:

The Timken Fafnir GRA111RRB 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 to heavy 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 a molded shroud seal to protect against contamination while retaining lubricant. The eccentric locking collar provides secure shaft locking for dependable operation in normal shaft rotation applications. It is widely used in conveyors, agricultural equipment, material handling systems, packaging machinery, fans, and general industrial equipment. Maintenance teams, OEMs, and system integrators specify the GRA111RRB for equipment replacement, retrofit projects, expansion, and preventive maintenance to improve equipment reliability and reduce downtime.

Applications:

The Timken Fafnir GRA111RRB insert ball bearing is designed for mounted bearing housings requiring secure shaft retention and the ability to accommodate minor shaft misalignment. Its eccentric locking collar provides positive shaft engagement, while the spherical outer diameter ensures proper seating within compatible housings. Typical applications include conveyors, agricultural machinery, packaging equipment, food processing systems, fans, textile machinery, and industrial material handling equipment.
