Product Description

The INA GE 30 KRRB Insert Ball Bearing is an insert bearing with a 30 mm bore, a 62 mm outside diameter and an overall width of 48.4 mm. It is designed for installation in compatible mounted bearing units with a spherical housing seat, allowing reliable shaft support and simplified bearing replacement during maintenance.

The bearing features a spherical outside diameter that enables proper seating within bearing housings designed for insert bearings. This design helps compensate for minor shaft misalignment while maintaining stable bearing operation inside the housing unit.

Insert ball bearings are widely used as replaceable rolling elements in mounted bearing assemblies. Their standardized dimensions simplify maintenance, repair and overhaul (MRO) by allowing quick replacement without changing the complete housing assembly.

The INA GE 30 KRRB is suitable for industrial maintenance departments, machinery manufacturers and service workshops requiring a precision insert bearing with standardized dimensions. Common search terms include INA GE 30 KRRB, insert ball bearing 30x62x48.4, mounted unit bearing and spherical outside bearing.
