Insert Bearings are simply standard Radial Bearings that have been adapted to fit into a Bearing Housing (aka Plummer Blocks or Pillow Blocks), which is why they are often referred to as adapted radial bearings. Insert Bearings are commonly sold with a housing, they can also be purchased without one. 

Insert bearings typically have a spherically shaped (convex) outside surface and an extended inner ring with different types of locking device. The various insert bearing series differ in the way the bearing is locked onto the shaft.  Some are locked onto the shaft with Set Screws, some are locked with Eccentric Locking Collars, some are locked with Adapter Sleeves, or with Interference Fit.

Insert bearings with an inner ring that is extended on both sides run more smoothly, as the extent to which the inner ring can tilt on the shaft is reduced.

Along with wide inner ring bearings, insert bearings are used in many different industries, from agriculture and food processing, to printing.

The UK 200 series are insert bearings with a tapered bore which,

• are suitable for applications for both constant and alternating directions of rotation

• fit the following adapter sleeves:
  

  H 23 series for metric shafts
  

  HA 23, HE 23, and HS 23 series for inch shafts

• permit the full limiting speed to be achieved when mounted on an adapter sleeve, even where using commercial grade shafts

Note: The associated adapter sleeves must be ordered separately from the bearings.
