HRC Couplings

HRC Couplings

"HRC" is a registered trademark of the Fenner Group, but has become a widely used, generic term, to describe this coupling design.
HRC couplings consist of 2 cast-iron halves attached to shafts through either hub mount (H Flange) or face mount (F Flange) taper bushes. Between these two halves is a rubber "spider" that serves as a shock absorber. HRC Couplings allow for a limited parallel misalignment (0.5mm) and axial misalignment (1.7mm).

HRC Coupling Specifications

Features of HRC Couplings

Economy: The design of the HRC coupling has been optimized so that power capacities are balanced to the appropriate shaft diameters utilizing Taper-lock Bush fixing

Resilience: Transient peak loads are reduced by flexible components, the deflection of which is a prime design consideration

Misalignment: Incidental parallel, angular and axial displacement of the connected shafts can be accommodated

Installation: Quick and easy without special tools; only an allen key is required

Maintenance: Virtually eliminated, and no lubricant is required

Environment: The elastomeric component makes HRC coupling suitable for use in most conditions within a temperature range of -40鈩?to +100鈩?/p>

Positive: In the unlikely event of the flexible component being destroyed, the drive will be maintained by the interaction of dogs which are integral with the flanges
