High Strength & Low Weight

The strength of the steel used in our products 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.

Exceptional Arc of Support

Our steel blocks are designed to ensure shape of your rope is maintained under normal load

High Efficiency Bearings

Jeamar fits its steel blocks with high-efficiency, deep-groove, double ball bearings. This provides maximum efficiency, reduced friction, smooth motion, long life and high speed.
