Frequently Asked Questions
How do I choose the right hub size?
Begin by measuring your shaft diameter and noting whether it is in inches or millimeters. Then, select a hub with an outside diameter that fits your spatial envelope and meets torque requirements. The available outside diameters range from 3/4 in to 3 1/8 in, and 15 mm to 50.8 mm.
What types of hubs are available in this family?
The family includes inch and metric aluminum hubs. All variants are aluminum, but they differ in dimensional standards (inch vs. metric) and outside diameter sizes.
