The ball screw
that can keep up
with your duty cycle.
Recirculating-ball motion conversion at >90% efficiency — engineered for the high-speed, high-duty positioning where lead screws fall off the back. Configurable leads, low backlash, and end-machining done in-house. Request a sample sized to your axis.

Why engineers spec PBC ball screws
High-efficiency rotary-to-linear motion with the precision, life, and configurability that hard-running positioning systems demand.
High mechanical efficiency
Recirculating balls deliver >90% efficiency — drive smaller motors, lose less heat, last longer between rebuilds.
Low backlash
Preloaded ball nuts virtually eliminate axial play. Position repeatably under reversing loads without hysteresis.
Ground or rolled
Rolled screws for cost-sensitive duty; ground screws for tighter lead accuracy. Specify what your application needs.
End-machined to print
Bearing journals, keyways, and threaded ends machined in-house — no secondary shop, no lead-time hit.

We replaced an imported screw on a high-cycle machine and dropped both the motor draw and the rebuild interval. After [VERIFY] cycles, no measurable wear.
High duty cycle.
Low backlash.
