Hubs/Clamps

These clamping hubs are a great and cost-effective choice when attaching hub mount gears or wheels to shafts or tubes and can be a better option than set screw hubs if you don't want to risk damaging whatever you need clamped. These clamping hubs have a 5mm bore, four 6-32 tapped holes, one 6-32 machine screw for tightening, and utilizes the 0.77" hub pattern.

This hub adapter lets you connect Actobotics parts with a 0.77" hub pattern to parts with a 1.5" hub pattern. The holes for the 1.5" pattern alternate between tapped and untapped, whereas the inner 0.77" hole pattern is all un-tapped. These adapters are ideal for mounting two different hub patterns: mating hubs to gears, sprockets, or wheels. Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two...

These quad hub mounts can attach to the end or the middle of Actobotics channels to provide you a 90 degree angle with additional attachment points for Actobotics project. Additionally these hub mounts can be coupled with precision gearmotors for additional mounting possibilities These hub mounts have a width of 1.32”, a thickness of 0.34”, a 0.50” bore, and utilize both the 0.77” and 1.5" hub patterns.

Set screw hubs offer a cheap way to attach hub mount gears or wheels to a shaft. The hub offers 4 equally spaced 6-32 tapped holes utilizing the 0.77" hub pattern and is precision machined from 6061 T6 aluminum. The set-screw is 10-32 and uses a 3/32” hex key. This hub has a 1/4" bore. Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be...

The universal aluminum mounting hub allows you to mount custom wheels and mechanisms to 5 mm motor shafts. The hubs are sold in pairs. The set includes one Allen wrench and two 4-40 set screws for securing the hubs to motor shafts. Documents: Dimensional Drawing
