Timken GC1111KRRB-COL Radial Insert Ball Bearing

Description:

The Timken Fafnir GC1111KRRB + COL is a wide inner ring insert ball bearing with a concentric 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 shroud seal to protect against contamination while retaining lubricant. The concentric locking collar secures the bearing to the shaft using two set screws positioned 120 degrees apart, providing positive shaft retention and dependable performance. It is widely used in conveyors, agricultural machinery, material handling systems, packaging equipment, fans, and general industrial machinery. Maintenance teams, OEMs, and system integrators specify the GC1111KRRB + COL for equipment replacement, retrofit projects, expansion, and preventive maintenance to improve equipment reliability and minimize downtime.

Applications:

The Timken Fafnir GC1111KRRB + COL insert ball bearing is designed for mounted bearing housings requiring secure shaft retention and the ability to accommodate minor shaft misalignment. Its concentric locking collar provides even clamping force around the shaft, while the spherical outer diameter allows proper seating within compatible housings. Typical applications include conveyors, agricultural equipment, food processing machinery, packaging systems, textile machinery, fans, and industrial material handling equipment.
