Category: Ball Screw Support Bearing
Rolling Element: Steel Balls
Seal Type: Sealed and Open
Structural Features: the rings are made of bearing steel with high purity (Electro-slag remelting ESR). The special technology of heat treatment, cold treatment and material modifications leads to the dramatic increase in the fatigue life of bearing. The structural design of 60° contact angle and large number of steel balls enhances the axial rigidity. Compared with the cylindrical roller bearings and tapered roller bearings, this type of bearings has smaller staring torque, which achieves high precision rotations under low driving force. Paired bearings can support axial and radial loads.
Contact Angle: 60°
Cage: Nylon
Speed Factor: Grease :DmN≤400000 (that is, limit speed N≤400000/Dm
Applications: mainly used for precise axial positioning and repeated positioning, etc. for example, CNC lathe ball screw support, CNC universal grinding machine screw support, Automatic CNC bearing ring grinding machine screw support, CNC machining center screw support, and other types of CNC precision transmission mechanical screw support.
