HRC Coupling Assemblies with Natural Rubber (Most Common Applications) Insert

HRC coupling assemblies with natural rubber inserts are suitable for a wide range of transmission coupling applications. They are used in electric motors, hydraulic machinery, agitators, fans, conveyors, pumps, wood-turning equipment, milling machines, paper mills, crushers and compressors. Although accurate alignment of the coupling is important, the high-quality rubber inserts are very effective at absorbing shock and vibration.

These ordinary rubber inserts are reliable between about -15 to +70 degrees Centigrade. If fire or static hazards are a significant risk in your intended application, consider F.R.A.S. certified coupling assemblies based around chloroprene inserts instead (available in another section of the catalogue). Replacement rubber and chloroprene inserts are also available separately.

For clarity and to confirm dimensions, always consult the cross-sections provided under the "Technical" tab within individual product descriptions.

If you are attempting to design shaft couplings for a particular project, charts are available indicating the power transmission capabilities of different types and widths of coupling. Bear in mind that if your machinery is subject to mechanical shocks and vibrations, a heavier-duty coupling will be sensible compared to that needed for a smooth running motor. Accurate alignments also serve to minimise vibration or pulsing tendencies in the assembly. The couplings we supply are therefore guaranteed for their accurate machining.

This modular construction facilitates easy assembly and maintenance, and the intermeshing teeth of the two flanges ensure that your shaft coupling will be fail-safe in operation.
