Maxon 17mm Motor

This is the famous Maxon 216000 that is used in most rotary tattoo machines but with a bearing at the front end of the motors shaft for more durability.

We had Maxon make this improvement because 216000 comes standard with a bushing in this position that will wear from axial load on the motor over time. The increased performance and longevity of the motor is more than worth the added cost.
