Tough and hassle free our blocks are designed to accompany sheaves and pulley systems, with minimal maintenance for a longer operational life.

High Strength & 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.

Exceptional Arc of Support
Our steel blocks are designed to ensure shape of your rope is maintained under normal load conditions.

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.

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.

Block Loading
Jeamar blocks are rated for the full working load limit at 180° rope angle.

Lifetime Lubrication
Precision sealed bearings stay lubricated ensuring low maintenance.
