About The Precision Alliance (TPA)

What We Do

TPA supplies precision linear and rotary motion components and systems for machine, instrument, device, and vehicle applications. These components include linear bearings of a variety of types, ball screws, shaft couplings, linear motors, thin section ball bearings, turn table bearings, specialty gears, and related components.

Exceptional customer service is the lifeline of TPA's business. We clearly communicate with you about your orders and make every effort to fulfill your orders on time, every time. When you call us, a person (not a machine) answers the phone.


TPA's vast product offering enables us to offer designers the right solution for the application, instead of trying to make a limited offering fit the task. At last count we offer over 10,000 different product types from ultra-high precision to very basic bearing systems and from ultra-high capacity down to the world's smallest. The Right Product for Each Application.

When you contact TPA you can talk to a degreed engineer with both decades of industry experience and extensive product knowledge that can give you answers.


Although we offer catalogs full of linear bearings, ball screws, shaft couplings, gears, etc., our greatest successes are when we help you solve a linear motion problem. Often a catalog product will solve most problems. However, new projects tend to push beyond standard product offerings (i.e., load, temperature, size, environment, or something else).

TPA's unique business structure sustains very low overhead while maintaining highly responsive customer service and technical support teams. The low overhead coupled with a lean and efficient organization enables TPA to remain price competitive.
