Detailed introduction:

Z20 type expansion joint sleeveWith good interchangeability and excellent quality, it is the main product produced by our company.Our company has supporting production equipment, complete testing methods and instruments. The Z20 type expansion coupling sleeve is easy to disassemble. Because the expansion sleeve can combine the shaft hub with a larger matching gap, loosen the bolt when disassembling, so that the connected part can be easily disassembled.When swelling, the contact surface is tightly fitted and not corroded, and it is also easy to disassemble.

The basic dimensions and parameters of the Z20 expansion coupling sleeve:
