Fan Hub Boring and Bolt-Pattern Drilling

We bore the center and drill your bolt pattern on a blank fan hub in our machine shop, so it bolts straight onto your motor or shaft. One flat price per hub: $195.75 for a standard bore and bolt pattern.

How to order

1. Add the hub to your cart.
2. Add this machining service, one per hub.
3. In the order notes at checkout, give: the bore (shaft) size, the bolt circle diameter, and the number and size of the bolt holes. Or email us a drawing or a photo of your old hub with measurements.

We confirm the dimensions with you before we cut metal.

Needs a quote first

Keyways, counterbores, tapered or metric-tolerance bores, more than one bolt pattern, or anything unusual: call (360) 661-0875 or use the fan identification form and we will quote it before you order.
