Alternative Shaft Fixing Option:
These HRC Flexible Spider Couplings are available in eight sizes with the Pilot Bore hub version caters for shaft sizes from 9.0mm to 130.0mm and the Taper Bored hub versions catering for a shaft size range from 9.0mm to 100mm with a torque capacity range of 31.5nm to 7200nm. The flexible element acts as a buffer against peak loads and allows up to 0.5mm of parallel misalignment and 1.7mm of axial misalignment and suitable for use in operating conditions with ambient temperatures of -40c to +100c. The stock range includes three hub types, the H and F type hubs are design to be use with a Taper bush for direct shaft mounting and the B type hub has a nominal pilot bore and therefore can be re-machined to suit individual customer's shaft sizes on quick lead times as required?
A Free Design selection service is available for this product for full details and application requirements please use the link below?
As an alternative to either Boring & Keywaying a pilot bore pulley or using a Taper bored pulley and Bush!
Why not take a look at the range of Locking Bushes we now offer, as they eliminate the need for fixing via a Keyway-Key thereby providing the added benefit of a uniform distribution of the drive load over the entire diameter of the bush?
