BX Gear Couplings with Polyamide Sleeve

BX are torsionally flexible, puncture-proof shaft couplings with two metal hubs and a polyamide sleeve with internal gearing. They transmit torque through pressure-stressed elastic ring which absorbs shock and torsional vibration. BX coupling hubs are made of steel as unbored. This element is oil resistant and electrically conductive.

BX couplings can be used for both directions of rotation and each mounting position.

  2. Sleeve

Couplings Fields of Use

BX gear couplings are designed for the highest requirements in a wide range of industries, especially for compressors, pumps, conveyors, construction machinery and many other machines.

They are available in several designs and different sizes.

Couplings Characteristics

  • Compact design, reduced weight and moment of inertia
  • Constant-velocity movement
  • Noiseless running, elastic damping of shocks and vibrations
  • Resistance to the most common chemicals and to moderate heat, up to +80 °C
  • Self-lubricating, non-conductive and maintenance-free
  • Reasonable price, easy to mount, suitable for multiple duties, even the heaviest ones
