Sleeve and Clip Bearings
Sleeve bearings, sometimes called bushings, journal, or plain bearings, are used in rotary applications to reduce friction between two moving parts. They have no moving parts to wear out and rely on lubricant to rotate freely. They have a wide surface area and distribute the load over the entire width of the bearing, allowing them to handle higher loads than ball or roller bearings. Sleeve bearings can be installed where space is limited because they are more compact than roller bearings. Clip bearings have an angled slit through the width of the bearing, enabling the bearing to be installed from one side. The slit allows the bearing to change size as the temperatures and moisture levels fluctuate. The shaft holds the bearing in place and flanges on both sides ensure that the bearing does not move, even with axial movement.
