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.

/ 01

Anti-backlash option

Spring-loaded polymer nuts virtually eliminate backlash for repeatable, hysteresis-free positioning.

/ 02

Configurable leads

From fine pitch for resolution to high lead for speed — match the screw to your motion profile, not the other way around.

/ 03

Quiet operation

Polymer-on-steel running surface eliminates the chatter of metal-on-metal. Ideal for lab and medical environments.

/ 04

End-machined to print

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

What happens next

From form submit to sample on your bench — predictable, fast, and human.

/ STEP 01

You tell us about your axis

Load, travel, application. The form takes 30 seconds.

/ STEP 02

An engineer sizes the sample

We match a stocked size to your duty — or flag a custom before we ship, if your application calls for one.

/ STEP 03

It lands on your bench

Stocked sizes ship same business day. You test. We follow up only if you want us to.

Will I get a sales call?
Only if you ask. We confirm fit, ship the sample, and send technical follow-up. Anything more is your call.
What if I need a custom size or end-machining?
That's the norm, not the exception. Tell us what you're trying to do — application engineering will scope and quote it.
How fast does the sample ship?
Stocked sizes ship same business day. Custom sizes typically ship within 2–3 business days.

Spec the screw,
then test the screw.
