Free Ball Screw Sample

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.

Request your sample

Tell us about your axis — load, speed, travel — and we'll send a screw sized to it.

Confirmation in 60 seconds. Email lands the moment you submit.
Sample ships within 2 business days. Stocked sizes go same-day.
No sales calls unless you ask. Engineering follow-up only.

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.

From the field
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.

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.

High duty cycle.
Low backlash.
On time.
