The Timken Company GRAE25RRB Ball Insert Bearing

Description:

The Timken GRAE25RRB 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 a molded shroud seal to protect against contaminants while retaining lubricant. 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 GRAE25RRB insert bearing for equipment replacement, retrofit projects, expansion, and preventive maintenance to improve equipment reliability and reduce downtime.

Applications:

The Timken GRAE25RRB insert ball bearing is designed for mounted bearing housings requiring self-aligning capability and secure shaft locking. Its eccentric locking collar provides dependable shaft retention in normal rotational applications, while the spherical outer diameter allows the bearing to accommodate minor shaft misalignment. Typical applications include conveyors, agricultural machinery, food processing equipment, packaging systems, textile machinery, fans, and industrial material handling equipment.
