Radial insert ball bearings are single row, rady-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides, cages made from plastic or sheet steel and P, R, L or T seals. Bearings with an inner ring extended on both sides undergo less tilting of the inner ring and therefore run more smoothly.
The outer ring has a spherical or cylindrical outside surface. In conjunction with an housing matched to the bearing type
Insert ball bearing are located on the shaft by means of an eccentric locking collar, set screws in the inner ring, an adapter sleeve, drive slot or fit. Radial insert ball bearings are easy to fit, suitable for drawn shafts of grade h6 to h9 and, with a few exceptions, can be relubricated.
Some series with an eccentric locking collar and with grub screws in the inner ring are also available with an inch size bore.
WIS bearings supply insert ball bearings like : UCseries , SA series , HA series , UK series , SER series ect.
The bearing comes with an adapter sleeve, which is a cylindrical sleeve that slides over a tapered shaft. The inner surface of the sleeve typically has a taper that matches the shaft's taper.
Eccentric collar bearing inserts are often used in combination with pillow blocks or other types of bearing housings. The eccentric collar allows for easy installation and adjustment within the housing.
