Power your machinery with the Z4 Expansion Sleeve that distinguishes itself from standard locking assemblies by featuring larger radial dimensions. The sleeve ensures excellent concentricity, reducing vibration and noise in large rotating equipment such as heavy crushers, large flywheels, and mining conveyor pulleys.

This robust design allows the Z4 to generate higher contact pressure, making it the ideal solution for applications requiring maximum torque transmission and resistance to heavy shock loads.
