The PR23 series of pulley reducers provides a cost-effective alternative to gear reducers often costing $400 or more. Use the PR23 with any NEMA size 23
stepper or servo motor to provide a precise increase in resolution and torque. Vibration reduction and load matching benefits can also be achieved to enhance the
performance of many mechanical systems. Perfect for belt-driven and lead screw-driven XY positioning tables. Even though the output speed is reduced by the
reduction ratio, some systems will actually have their overall speed performance increased due to better matching of the motor with the load. This is particularly true on our
X and XY belt-driven positioning tables where speed can be increased by as much as 4 times by simply adding a 2.5:1 reduction. The PR23 face plate appears as a
size 23 motor with a 1/4" shaft. This allows the user to simply remove the motor from the mechanical system, mount it to the reducer, then mount the reducer on to
the system. Timing belt tension is easily adjustable. Pulleys can even be swapped within the housing to provide an 'increase' function if needed. Four models are
available providing ratios of 2:1, 2.5:1, 3:1 and 4:1. The simple yet rugged design incorporates precision ball bearings and requires no maintenance. Everything you need
is included pulleys, belts, hardware and wrenches.
