FAG 1100KRRB Wide Inner Ring Ball Bearing Insert with Eccentric Collar

The FAG 1100KRRB is a standard-duty, wide inner ring ball bearing insert designed for demanding industrial and agricultural applications. Featuring a 1-inch bore, 2.0472-inch spherical outside diameter, and 1-3/8-inch inner ring width, this bearing insert is engineered for reliable performance on straight shafts without the need for shoulders or locknuts.
