Angular Contact Steel Bearings: overview
Use this page to choose a high speed spindle bearing with steel balls. A P4 spindle bearing (ABEC 7 class) is the usual precision class for CNC spindles; confirm the class you need when ordering. If your spindle is rated for an angular contact ceramic bearing, replace it with ceramic, not steel. The 72xx series, such as a 7202 bearing, is a heavier section than 70xx for the same bore and is used where loads are higher. Angular contact bearing price depends on size, contact angle, precision class and pairing.
Angular Contact Steel Bearings: frequently asked questions
What does DBB mean on an angular contact bearing?
DBB describes a matched set arrangement: bearings ground so that when mounted back-to-back they give the designed preload. Matched sets must be fitted in the marked order and orientation; mixing bearings from different sets changes the preload and shortens life.
