4S-7062: 12" Outer Diameter Mast Sheave

The Mast Sheave is connected to the assembly of the mast through a central bore or hub, employing fastening methods such as bolts, screws, or keyways to secure a connection. This connection provides proper alignment and minimizes any potential for misalignment-induced wear or inefficiencies in energy transfer. Its design incorporates a groove or channel that accommodates a belt or rope. This engagement results in the controlled transfer of rotational motion and torque from the pulley. The assembly consist of cup bearing and seal. Attributes: • Allow seamless engagement between the sheave and the pulley • Provide high mechanical strength and wear resistance • Provide with 5 equally spaced holes to place the part in the assembly Applications: The Mast Sheave is used in the lower hook block to mast setup to enable efficient transmission from the pulley and ensures precise alignment and reliable energy transfer within the unit.
