The raceways in these bearings are positioned off-center to handle angular (combined radial and thrust) loads.

Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components.

In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

A built-in thrust ball bearing reduces wear from adjacent shaft components, while the needle-roller bearing supports radial loads.

A set of ball bearings reduces friction and secures the end of a ball or lead screw.
