Purpose-built insert bearing
The NTN UC310 insert bearing is a 50x110x32mm rolling-element component designed for shaft-mounting in electrician tool assemblies. It suits maintenance engineers and workshop technicians who need a direct replacement for worn or damaged units in existing equipment.
Sealed mounting and dimensional fit
The bearing’s 50mm bore, 110mm outer diameter and 32mm width determine the housing and shaft tolerances required for secure location. Correct interference fits prevent axial drift and misalignment during the high-vibration cycles typical of power-tool gearboxes.
Ready-to-install unit
Supplied as a complete insert bearing, the UC310 arrives pre-lubricated and sealed so no additional grease, adapters or locking collars are needed. This reduces bench time and eliminates the risk of contamination during assembly.

Questions about this item
What is the bearing inner diameter that determines shaft fit?
The inner diameter is 50 mm, which sets the shaft size the UC310 can accept.
What are the outer diameter and width that define the housing seat?
The outer diameter is 110 mm and the width is 32 mm, giving the housing bore and axial space needed.
How is the UC310 secured on the shaft, and what step is often missed?
Tighten the set-screw locking collar to the recommended torque; the step often missed is torquing both screws evenly.
