Radial Insert Ball Bearings

Radial insert ball bearings are single-row, ready-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides with cages made from plastic or sheet metal.

Radial insert ball bearings

Radial insert ball bearings are ready-to-fit machine elements. In combination with drawn shafts, they are particularly easy to fit and suitable for the design of economical bearing arrangements. They are highly suitable where predominantly radial loads must be supported.

The radial insert ball bearings have a spherical or cylindrical outside surface. They are predominantly located on the shaft by means of an eccentric locking collar or grub screws.

The bearings are sealed using a range of available standard seals that are matched to the different application conditions.

Radial insert ball bearings with an extended inner ring undergo less tilting and therefore run more smoothly.

Radial insert ball bearings with a spherical outer ring are highly suitable where:

  • static angular misalignments of the shaft must be compensated, which are caused by mounting inaccuracies and tolerances in the adjacent construction 
  • very good seals are required in environmental conditions such as dust, contamination, moisture, stone impacts and shocks

Radial insert ball bearings with a cylindrical outer ring are highly suitable where:

  • a cylindrical housing bore is already present
  • the outer ring of the bearings is to be located by means of easy-to-fit snap rings

Radial insert ball bearings with a profiled bore are highly suitable where:

  • shafts must transmit very high torques

Radial insert ball bearings with a rubber interliner are highly suitable where:

  • vibrations and shocks must be supported
  • damping of running noise is required
