About PM

We are an independent, family-run company specialized in the design of precision linear and rotating bearings and slides. Also, we develop highly accurate positioning and motion systems designed to customer specification.

We have been in business since 1966 when PM opened its doors as a manufacturer of crossed roller linear bearings. Over the course of the following decades, PM has gradually increased its portfolio size and continues to do so. This is reflected by our currently extensive product range. Through ongoing research and engineering projects, we are able to offer special positioning solutions customized to specific applications.

Modern manufacturing plant

All products PM offers are developed, designed, manufactured and assembled at our modern manufacturing plant in Dedemsvaart. A wide variety of highly automated machining centres belongs to PM’s standard inventory. Our in-house machining capabilities range from micro to macro scale and for instance, include: turning, milling, grinding and lapping. In our facility, we produce the critical components for the PM products like slide and stage parts, linear bearing cages, rails, adapter plates and wafer holders.



The assembly of components can be done either atmospheric or in our ISO class 6 or 7 cleanroom, depending upon customers’ desire. To ensure the highest grade of precision, the entire facility – from manufacturing to assembly – is climate controlled. High quality is guaranteed because made by PM really means made by PM.
