Bearing for shaft-mount applications

The NTN UC320 is an insert bearing built for shaft-mount installations where a self-aligning unit is required. It suits maintenance engineers and electricians who service conveyors, fans or agricultural equipment. The bearing replaces worn originals without needing a full housing change.

100 mm bore with 215 mm outer diameter

The single dimension that decides fit is the 100 mm bore matched to a 215 mm outer diameter and 55 mm width. These three figures must match the shaft and housing drawings exactly. No other size variant is offered under this part number.

Supplied as a complete insert unit

The bearing arrives ready to mount with its integral locking collar and seals already fitted. No separate adapter sleeves, snap rings or lubrication fittings are included in the package. Installers can press it into the existing housing and secure the collar immediately.

Questions about this item

What does the 100 mm bore mean when the NTN UC320 is fitted on a shaft?

The 100 mm bore matches a shaft of that diameter so the inner ring sits directly on the shaft without an adapter sleeve.

Which mounting standard does the NTN UC320 follow and what does it limit?

The UC320 designation follows the set-screw insert bearing standard, fixing the 100 mm bore, 215 mm outside diameter and 55 mm width to industry dimensions.

What housing bore and shoulder width are needed to mount the NTN UC320?

A housing bore of 215 mm and a shoulder width of at least 55 mm are required to seat the outer ring and inner ring respectively.
