Engineered for accuracy. Trusted for performance.

KJK Precision is a specialist supplier of rack and pinion drive systems for machine builders who will not compromise on accuracy.

Who we are

A specialist in rack and pinion drive technology

KJK Precision was founded with a single focus: to supply rack and pinion drive systems that machine builders can rely on without compromise.

We specialise in precision gear racks, pinions, guideway racks, rollers and clamping elements, the components that decide how accurately and how long a machine will perform.

Behind the KJK name is a team with years of hands-on experience in linear motion and power transmission. We understand the demands of modern machinery because we have spent our careers solving them, from selecting the right module for a high-speed gantry to aligning racks across a 20-metre axis.

Our approach

Quality you can specify with confidence

Every KJK product is manufactured to our specifications by carefully selected production partners and checked against defined standards for accuracy, hardness and finish before it carries our name.

The result is a product range our customers can specify with confidence, knowing that a KJK rack ordered today will match the one they ordered last year.

We combine this product quality with the support engineers expect: complete catalogues, 2D and 3D CAD data, sizing assistance and quick, clear answers.
