Details

• Structural features: The inner and outer rings are made of high-purity bearing steel that strictly controls oxide impurities that are harmful to rolling fatigue life. The contact angle is 60º and the number of steel balls is large. The axial rigidity of the BS sealed series screw bearing is improved. Large; compared with tapered roller bearings and cylindrical roller bearings, the starting torque is small, and low driving force and high-precision operation are realized; when used in pairs, it can bear axial load and radial load or composite load.
• Contact angle: 60°
• Cage: Nylon cage guided by rolling elements.
• Speed factor: Grease lubrication DmN≤400000, that is, the limited speed N≤400000/Dm Dm—bearing diameter
• Scope of application: Mainly used in working conditions that require precise axial positioning and repeat positioning accuracy. For example: CNC lathe screw support, CNC grinder screw support, automatic CNC bearing ring grinder screw support, CNC machining center screw support and other types of CNC precision transmission machinery screw support.
