We make all kinds of hubs. Some with tapered bores some with staight, some with internal keyways some with external keyways. Internal and external pilots. Companion flanges of many types. Diameters up to 16 in. Send me your Cad file, your PDF, your napkin with a drawing, we will quote you asap. Don't forget to include material type, tolerances of important features. If you are trying to keep costs down, only ask for super tight tolerances down to (+/- .0005) where necessary. We will work to +/-.005 on the rest of it.
