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.
Our steel blocks are designed to ensure shape of your rope is maintained under normal load conditions.
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.
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.
Precision sealed bearings stay lubricated ensuring low maintenance.
Due to our policy of continuing development, all specifications are subject to change without notice. Users of these products are responsible for ensuring their suitability for the application in which they are being used.
