Shaft Couplers

If you need to connect this shaft to a motor or another device with a shaft, you can use a shaft coupler:

Pulleys and Sprockets

If you're using a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the system. Pulleys and sprockets can also be used to transmit rotation over a long distance. For more guidance on building a transmission system, visit our Rotary Motion Primer. Here is a list of our 8mm bore pulleys and sprockets:

Rotary Bearings

Systems with heavy loads or pulley/sprocket assemblies often put a lot of sideways strain on the shaft. In such a system, you can use rotary bearings to protect and support the shaft:
