CONCENTRIC COLLAR
• The piloted flange cartridges ensure accurate
mounting fits and provide better support for
heavy loads.
• The cast-iron units are suited for applications
such as material handling, industrial conveyor
equipment, and farm and construction
equipment.
• This series is assembled with R-seal (GC-KRRB)
bearings with a concentric-locking collar.
• The units are factory-prelubricated. A grease
fitting is provided for relubrication if required.
