The EP gearboxes are planetary units suitable for use with servo,

stepper and other types of motors.

 

The EP gearboxes offer medium backlash, mathematically accurate ratios up to 100:1

and high efficiency.

 

One and two stage versions of the gearboxes are available and they are suitable

for intermediate input speeds up to 5000rpm.
