Jeamar Single Swivel Directional Blocks

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, for maximum efficiency, reduced friction, smooth motion, long life and high speed.
  • 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 rope’s 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.
  • Jeamar blocks are rated for the full working load limit at 0° rope angle.
