PBC Linear lead screws convert rotary motion to linear motion with the smoothness and repeatability your positioning system demands. Custom leads, anti-backlash nut options, and end-machining to print — request a sample sized to your axis.

Why engineers spec PBC lead screws
Configurable leads, anti-backlash nut options, and end-machining done in-house — engineered to drop into your positioning axis without compromise.
Anti-backlash option
Spring-loaded polymer nuts virtually eliminate backlash for repeatable, hysteresis-free positioning.
Configurable leads
From fine pitch for resolution to high lead for speed — match the screw to your motion profile, not the other way around.
Quiet operation
Polymer-on-steel running surface eliminates the chatter of metal-on-metal. Ideal for lab and medical environments.
End-machined to print
Bearing journals, keyways, and threaded ends machined in-house — no secondary shop, no lead-time hit.
