Our clamping hubs offer a cheap way to attach our hub mount gears or our wheels to a shaft. This hub offers 4 equally spaced 5-40 tapped holes and is precision machined from 6061-T6 aluminum. Clamping hubs offer several advantages over set screw hubs. First, they do not damage the shaft which they are attached. Second, they offer more holding power in high torque applications. The disadvantage is that they are not as equally balanced for high speed use. The side clamping machine screw is 5-40 and accepts a 3/32” hex key.

These hubs use a 3/32” Hex Key

Our clamping hubs offer a cheap way to attach hub mount gears or wheels to a shaft. Clamping hubs offer several advantages over set screw hubs. First, they do not damage the shaft which they are attached. Second, they offer more holding power in high torque applications. The disadvantage is that they are not as equally balanced for high speed use. The side clamping machine screw is 6-32 and accepts a 7/64” hex key. These clamping hubs work with our new ServoBlocks Kits.

NOTE: As of this time, the 0.770” Clamping Hubs are not compatible with our gears, sprockets, wheels, etc.
If you are looking for a Clamping Hub that will attach to an item previously purchased from ServoCity you will most likely require the 0.625” Hub listed above. If you are unsure which hub to purchase, please e-mail tech@servocity.com or call 620-221-0123 before completing your order. Thank you.
