Stainless sheaves are available in standard sizes from 2 inch to 16 inch and from 3,500 and 41,000 lbs working load limits. Vertical and horizontal directional blocks are also available in stainless steel to complement the three sizes of sheaves. For maximum flexibility, the dimensions of Jeamar’s stainless steel sheaves and blocks are identical to our standard line of heavy-duty sheaves and blocks. Custom sizes are available to meet your exact requirements of size and capacity.
All Jeamar stainless steel sheaves come standard with lifetime lubricated, sealed, deep-groove ball bearings for long life and minimum maintenance.
Jeamar stainless steel sheaves are rated for the full working load limit at 180° rope angle.
Jeamar sheaves have a minimum sheave-to-rope ratio of 15:1. This ensures a large radius for the rope to bend around, which in turn decreases flexing of the rope and substantially increases rope life.
Designed with a minimum arc of support for the rope of 125 degrees, ensuring that the rope’s cross sectional shape is maintained under normal load conditions. This increases rope life and increases sheave life by reducing gouging.
