The Timken Company G1103KRRB Ball Insert Bearing

Description:

The Timken Fafnir G1103KRRB with S1103K locking collar is a wide inner ring insert ball bearing 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 with positive-contact sealing to protect against contamination while retaining lubricant. The S1103K eccentric locking collar provides secure shaft retention 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 equipment. Maintenance teams, OEMs, and system integrators specify the G1103KRRB with S1103K collar for equipment replacement, retrofit projects, expansion, and preventive maintenance to improve equipment reliability and reduce downtime.

Applications:

The Timken Fafnir G1103KRRB insert ball bearing is designed for mounted bearing housings requiring secure shaft locking and the ability to accommodate minor shaft misalignment. Its spherical outer diameter allows proper seating within compatible housings, while the S1103K eccentric locking collar provides positive shaft engagement during operation. Typical applications include conveyors, agricultural machinery, food processing equipment, packaging systems, textile machinery, fans, material handling equipment, and other industrial rotating machinery.
