High Quality
Jeamar steel sheaves are precision made from the highest quality
fine-grain steel. They're tough, hassle free and they last
longer.
High Strength with Low Weight
Jeamar steel sheaves are stronger and up to 50 percent lighter.
They're easy to handle and install.
Exceptional Arc of Support
Jeamar steel sheaves ensure that the shape of your rope is
maintained under normal load conditions.
High Sheave to Rope Diameters
With a minimum diameter of 16:1, the rope's bending stress is
reduced for longer life.
Work Hardened
Rope grooves are hardened during forming, increasing the life of
sheave and rope.
Taper Roller Bearings
Taper roller bearings with a high side load capacity are standard
in Jeamar snatch blocks. These bearings overcome the side loads
imposed during the initial tensioning of the wire rope, extending
the life and increasing the efficiency of the snatch block.
Easy Installation
The drop side is secured by a simple non-removable
attachment with an additional 'secure pin'. The design allows the
rope to be installed and removed quickly and easily.
Due to continuing development, all specifications are subject to change without notice.
