Expansion sleeve model: Z11 type
Expansion sleeve surface treatment: light decoration, polishing
Expansion sleeve material: 45#,40Cr,304,430, etc.
Expansion sleeve use: can be connected to a wheel hub with a small inner diameter.
Expansion sleeve features: can be connected to a wheel hub with a small inner diameter.There is a self-centering function.When connected, there is no axial movement of the hub.
Expansion sleeve usage method: combination and disassembly should be operated according to the usage method on the data page.When using, basically do not degrease.Degreasing may reduce the transmission torque, so special attention is required.It can be used in multiple stages, but it must be combined according to regulations, such as confirming the strength of the wheel hub and strictly managing the connection torque.At the same time, the transmission torque is not doubled according to the combined quantity.Therefore, special attention is required.
Precautions for expansion sleeves: It is recommended to perform heat treatment such as quenching on the hub and shaft.Insufficient shaft strength results in reduced transmission torque, or the connecting ring is attached to the shaft and cannot be pulled out of the connection. After disassembly and reuse, pay attention to the deformation and lengthening of the bolt.When the bolt is deformed and becomes longer, it cannot be reused.New bolts need to be replaced.
