The GN303KRRB Insert bearings primarily consist of a spherical outer ring, a wide inner ring, steel balls, a cage, and seals. The inner ring extends at one or both ends and is equipped with an eccentric sleeve or set screw for quick locking onto the shaft.
Insertion bearings are suitable for applications with limited installation space and requiring frequent maintenance. Classic applications include agricultural machinery, conveyor equipment, textile machinery, construction machinery, food processing equipment, and fan and air conditioning units. feature self-aligning capabilities, compensating for installation misalignment and shaft deflection. The wide inner ring design allows for direct installation onto the shaft without additional steps. They offer excellent sealing performance, a compact structure, and easy assembly and disassembly.
