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.
