K24 Ball Bearing Mini Motor Gearhead
K24 (Ball Bearing)
The combination of our K24 spur gearheads with our brush DC coreless motors provides a single, factory-integrated solution for demanding, high-efficiency applications. Due to its spur compound geartrain arrangement, it provides the output in the same axis as of the motor. The K24 gearheads inherent design results in overall better efficiency and lower noise which are the requirements for wide ranging applications like medical pumps, security and access and luxury goods.
