Frequently Asked Questions
How do I choose the right hub size?
Start by measuring your shaft diameter and the space available for the coupling. Then, refer to the outside diameter range (3/4 in to 3 1/8 in, or 15 mm and 50.8 mm) to find a hub that fits. Ensure the hub's bore size matches your shaft.
What material options are available?
The hubs come in aluminum and inch-based variants. Aluminum is lighter and reduces rotational inertia, while inch variants may offer different strength or compatibility with inch-sized shafts.
