Z7A Type Expansion Coupling Sleeve

Z11 type expansion coupling sleeve positioning, simple hub hole, wide application.Has good interchangeability.Since the expansion sleeve can combine the shaft hub with a larger fit gap, the bolts are loosened when disassembling, so that the connected parts can be easily disassembled.When swelling, the contact surface is tightly fitted and does not rust, and it is easy to disassemble. ...

Z12 type expansion coupling sets (Z12 type expansion sets) are widely used in: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, engineering machinery, various types of machine tools and interchangeable mechanical transmission connections. ...

Z13 type expansion sleeve is a kind of basic component widely used for mechanical connection under heavy load today. In the connection of wheel and shaft, it is a kind of load transmission by tightening the bolt to make the pressure and friction between the containing surface. Keyless coupling device. ...
