PBC Linear began in 1983 as Pacific Bearing Company, creating a patented and innovative solution to the common problem of failing linear ball bearings. Since then, we have greatly expanded our technology, expertise and services into a complete linear motion manufacturer. We specialize in providing our customers with everything from out-of-the-box components, to mechanical sub-assemblies, and even complete linear systems.

Headquartered in Rockford, IL, PBC Linear manufactures all of our products right at home-ensuring fast delivery, lower total costs, and reliable service. We also staff a full team of expert engineers-drawing experience from years of mechanical and design engineering disciplines both in the classroom and out in the field.

We channel our wide product knowledge and engineering expertise into all aspects of the manufacturing products; such as our newly designed SIMOTM machine (Simultaneous Integral Milling Operation). The SIMOTM process is the solution to aluminum extrusion inaccuracy. Each piece of aluminum extrusions has a natural bow, twist and camber which requires a lengthy machining and alignment process for accuracy; however this traditional method is costly and not fully effective.

The SIMOTM process uses synchronized cutters to concurrently mill all critical edges of an aluminum extrusion in one quick pass. This creates a piece of extrusion that is accurate, straight and consistent on all sides. The entire machining process-which used to take hours-now takes minutes! This allows PBC Linear to provide our customers with incredibly accurate length products at little to no extra cost.

At PBC Linear, we use our skilled staff, sophisticated tools, and innovative products to create long lasting solutions for your application. Our carefully designed and refined products have been strategically planned to solve the toughest problems in linear motion.

Redi-Rail® was created to meet the industry demand for faster, lighter and quieter linear motion applications. Combining lightweight structural components, precision steel inner raceways, and high-speed self lubricated roller bearings; Redi-Rail® delivers high-speed performance (8 meters/second), with continuous rail lengths available up to 19 feet (6m). Redi-Rail® Linear guides are also configured in V-Guide Systems to provide high speed, moderate load capacity in harsh environments.

Hevi-Rail®, heavy-duty Linear Bearing Systems provide high load capacity and simple installation. Hevi-Rail® is a sealed, self-lubricated bearing that is capable of addressing both radial and axial loads up to 41 KN. Utilizing Hevi-Rail® combination bearings, coupled with our complete line of accessories; eliminates components, reduces installation time, and subsequently lowers costs.
