The Standard Stock series have Pilot Bore Hubs and cater for shafts size from 6.0mm to 100mm, and provide a Torque range of 10nm to 7200nm, although for large volume users, we also provide a pre-machined shaft ready version, which are available upon request!

There are two hub types, the A type have the smaller outside diameter, with the B type have the larger full size outside diameter and can be used as mating pairs (A-A or B-B) or a combination of each,(A-B) which is the standard arrangement, as both types are stocked with a nominal pilot bore they can be re-machined to suit individual customer’s shaft sizes on quick lead times as required.

Be careful if you are only trying to replace just a hub or a spider as there are numerious Brands such as the Giflex, Rotex, KTR & FBX which are dimensional very similar but are not interchangeable? Therefore close attention need to be paid to the pitch of the spider as the can differ slightly? If in doubt replace the complete coupling!
