FAFNIR G 1112 KRRB / COL Wide Inner Ring Ball Bearing | 1-3/4 in Eccentric Locking | Heavy Duty Sealed
The FAFNIR G 1112 KRRB / COL is a high-performance wide inner ring ball bearing designed specifically for demanding industrial and agricultural applications requiring secure shaft positioning and exceptional debris exclusion. Featuring a robust 1.7500 inch (44.45 mm) bore, this unit incorporates an extended inner ring that provides superior shaft support and stability, mitigating tilting and edge stress typical in standard width bearings. The KRRB designation denotes double-sealed construction (synthetic rubber seals) optimized to retain factory lubrication and prevent the ingress of contaminants such as dust, dirt, and moisture. The unique eccentric locking collar (/COL) ensures a positive grip on the shaft, simplifying installation and removal while maintaining critical alignment, making it the preferred choice for pillow block and flange mounted units.
Engineered by FAFNIR, a leader in specialized bearing solutions, the G 1112 KRRB offers outstanding operational reliability in high-vibration and heavily contaminated environments, commonly found in conveying systems, harvesting machinery, and aggregate processing equipment. Its substantial dynamic load rating (C) allows for high-speed operation under significant radial and moderate axial loads. Selecting this genuine FAFNIR product ensures reduced maintenance cycles, prolonged service life, and minimized downtime, providing a superior cost-of-ownership benefit compared to standard alternatives. This bearing is pre-lubricated with a high-grade grease suitable for a broad range of operating temperatures.
