HRC Elastic Couplings
HRC are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a rubber element. They transmit torque through pressure-stressed elastic star-shaped buffer which absorbs shock and torsional vibration. This element is oil resistant and electrically conductive. HRC coupling hubs are made of grey cast iron as unbored, with a pilot bore or for fixing with Taper Lock bushes.
HRC couplings can be used for both directions of rotation and each mounting position.
Couplings Construction
- Hubs
- Buffer
Couplings Fields of Use
HRC flexible 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 two-piece cast iron design.
Couplings Characteristics
- Alignment of radial, axial and angular misalignment of shafts
- Parallel misalignment up to 0.5 mm, axial misalignment up to 1.7 mm
- Use for a temperature range from −40 °C to +100 °C
- High speed capability, cost effective solution
- Simple assembly without the need to modify the bore (applies to versions with Taper Lock bushings)
