Double Swivel Directional Block


Jeamar steel sheaves are precision made from the highest quality fine-grain steel. They're tough, hassle free and they last longer.


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.


Jeamar fits its steel sheaves with high-efficiency, deep-groove, double ball bearings. You get far less friction, smoother rope motion and longer life.


Jeamar steel sheaves ensure that the shape of your rope is maintained under normal load conditions.


With a minimum sheave to rope ratio of 15:1, the ropes bending stress is reduced for longer life.


Rope grooves are hardened during forming, increasing the life of sheave and rope.


Precision sealed, bearings stay lubricated ensuring low maintenance.

Important: Due to Jeamar's 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.
