Premium Steel
Sheaves with Bearings


Exceptional Arc of Support

At Jeamar all of our steel sheaves are designed with a minimum arc of support for the rope of 125 degrees, ensuring that the rope cross sectional shape is maintained under normal load conditions. In turn, this increases rope life by minimizing internal rope flexing and increases sheave life by reducing gouging. Note: It is essential that the correct size of sheave be used for the rope. For instance, a 1/2 in. diameter rope should be used with a sheave that has a 1/2 in. groove radius, to achieve optimum conditions.

Lifetime Lubrication

The ball and roller bearings are sealed and lifetime lubricated for long life and minimum maintenance costs.

High Efficiency Ball or Roller Bearings

Our premium steel sheaves incorporate either ball or taper roller bearings for maximum efficiency, reduced friction, smooth motion, long life and high speed.

High Sheave-to-Rope Ratio

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.

High Strength and Low Weight

The strength of the steel used considerably exceeds that of cast iron. Steel also has a weight-saving advantage of up to 50 percent over cast iron, resulting in easier handling and installation.

Notice

It is essential that the correct size of sheave be used for the rope. For instance, a 1/4 inch diameter rope should be used with a sheave that has a 1/4 inch groove, to achieve optimum conditions.
