Jeamar steel sheaves are precision made from the highest quality fine-grain steel. They’re tough, hassle free and they last longer.
HIGH STRENGTH AND LOW WEIGHT
The strength of the steel used by Jeamar 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.
HIGH EFFICIENCY BEARINGS
Jeamar fits its steel sheaves with high-efficiency, deep-groove, double ball bearings, for maximum efficiency, reduced friction, smooth motion, long life and high speed.
EXCEPTIONAL ARC OF SUPPORT
Jeamar steel sheaves ensure that the shape of your rope is maintained under normal load conditions.
HIGH SHEAVE-TO-ROPE RATIO
With a minimum sheave-to-rope ratio of 15:1, the rope’s bending stress is reduced for longer life.
Jeamar blocks are rated for the full working load limit at 180° rope angle.
The S 52000, S 68000 and S 83000 are supplied with double row cylindrical roller bearings.
