High Quality
Jeamar steel sheaves are precision made from the highest quality fine-grain steel. They're tough, hassle free and they last longer.

High Strength with Low Weight
Jeamar steel sheaves are stronger and up to 50 percent lighter. They're easy to handle and install.

High Efficiency Bearings
Jeamar fits its steel sheaves with high-efficiency, deep-groove, double ball bearings. You get far less friction, smoother rope motion and longer life.

Exceptional Arc of Support
Jeamar steel sheaves ensure that the shape of your rope is maintained under normal load conditions.

High Sheave to Rope Diameters
With a minimum diameter of 16:1, the rope's bending stress is reduced for longer life.

Work Hardened
Rope grooves are hardened during forming, increasing the life of sheave and rope.

Lifetime Lubrication
Precision sealed, bearings stay lubricated ensuring low maintenance.

Due to our policy of continuing development, all specifications are subject to change without notice.
