Push Off Sleeve

Withdrawal Sleeve, also called a withdrawal sleeve or a withdrawal ring, is a bushing part commonly used in mechanical assembly. The following is a detailed introduction:
- **Structural Features**: Usually a tapered sleeve, the inner hole matches the shaft, and the outer surface matches the inner hole of the bearing. Some withdrawal sleeves have longitudinal slots to facilitate expansion or contraction. There are threaded holes at the end for connecting pulling tools or bolts to apply disassembly force. The material is usually made of high-strength alloy steel, such as 42CrMo, and surface hardened to improve wear resistance.
- **Working Principle**: The axial movement of the cone surface is used to produce radial deformation. During installation, the sleeve is pressed in and radially expands to tighten the inner ring of the bearing and the shaft; during disassembly, apply axial force to the end threaded hole through hydraulic tools or bolts, and pull the sleeve out in the opposite direction to release the pressure and facilitate the removal of the bearing.
- **Function**: Mainly used to simplify the installation and disassembly process of bearings, gears and other components on the shaft. It can compensate for the dimensional deviation of the shaft and the inner hole of the bearing, ensure a tight connection, and at the same time reduce scratches or wear on the shaft surface during disassembly, extending the service life of the shaft.
- **Application scenario**: It is widely used in the maintenance of large bearings such as rolling mills and wind power spindles, as well as the maintenance of gears and couplings in heavy machinery transmission systems. It is suitable for precision components that require frequent disassembly and assembly.
- **How ​​to use**: During installation, insert the withdrawal sleeve between the inner hole of the bearing and the shaft, and tighten it with the lock nut. When disassembling, loosen the lock nut, screw the bolt into the threaded hole at the end of the withdrawal sleeve, tighten the bolt evenly to generate axial tension, and gradually withdraw from the bearing.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
