Tough and hassle free our blocks are designed to accompany sheaves and pulley systems, with minimal maintenance for a longer operational life. The S 52000, S 68000 and S83000 are supplied with double row cylindrical roller bearings.
Steel options available, view here.
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.
Our steel blocks are designed to ensure that the shape of your rope is maintained under normal load
Jeamar fits its steel blocks with high-efficiency, deep-groove, double ball bearings for maximum efficiency. This results in reduced friction, smooth motion, high speed and a longer operational life.
With a minimum sheave-to-rope ratio of 15:1, the rope’s bending stress is reduced for longer life.
Precision sealed bearings stay lubricated ensuring low maintenance.
Jeamar blocks are rated for the full working load limit at 180° rope angle.
