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.

/ 01

High mechanical efficiency

Recirculating balls deliver >90% efficiency — drive smaller motors, lose less heat, last longer between rebuilds.

/ 02

Low backlash

Preloaded ball nuts virtually eliminate axial play. Position repeatably under reversing loads without hysteresis.

/ 03

Ground or rolled

Rolled screws for cost-sensitive duty; ground screws for tighter lead accuracy. Specify what your application needs.

/ 04

End-machined to print

Bearing journals, keyways, and threaded ends machined in-house — no secondary shop, no lead-time hit.
