NBR UGB1632F Unground Flanged Bearing 25.4 x 50.8 x 12.7 mm

This NBR range covers 8 unground flanged bearings with a zinc plated finish and rubber seals: the UGB0818F, UGB0822F, UGB1018F, UGB1022F, UGB1222F, UGB2035F, UGB2547F and UGB1632F, from 12.7 to 25.4 mm bore and 28.57 to 50.8 mm outer diameter. Select the size from the drop-down: each size has its own part number, dimensions and weight in the Model Details.

Unground bearings are not finished to the tight tolerances of ground precision bearings, which makes them a practical choice for general purpose rollers, guides and wheels where fine accuracy is not needed. The flange on the outer ring locates the bearing against a shoulder or face, and the rubber seals help keep dirt out.

Where this product is used

• Sliding gates, doors and shutters
• Light conveyors, castors and packaging equipment

Features

Key specifications

Available sizes

Selecting the right option

Select by bore d, outer diameter D and flange diameter F: the flange has to seat against your housing face, so check F and the width dimensions A, B and E as well as the bore and outer diameter. Sizes are listed in both inch and metric: UGB2035F and UGB2547F are metric, the rest are inch bores.

Load ratings and speed limits are not listed for these bearings, so confirm the duty with AIMS before ordering for anything beyond light duty.

Fitting and use

Press on the ring that is being fitted, not the other ring or the balls: force goes through the side face of the inner ring on a shaft and through the outer ring in a housing.

Keep sealed bearings in their packaging until mounting and do not wash them.
