PBC Linear is a US-based manufacturer and online supplier of linear bearings, shafts, actuators, lead screws, slides, patented linear guide systems, rails and 3D printer parts. We can deliver products overnight from our sprawling factory complex in Roscoe, Illinois, 90 miles west of Chicago. 

The company's journey started in 1983 with groundbreaking self lubricating bearing liner technology that addressed the widespread issue of failing linear ball bearings. Four decades later, that innovative bearing design has evolved into a diverse range of creative products and services focused on linear motion technologies.

The manufacturing process is driven by a diverse team of engineers from various disciplines, including aerospace, medical, and commercial sectors. Their "Design on a Diet" philosophy focuses on streamlining product design and reducing cycle times via tools like SolidWorks® and Finite Element Analysis (FEA). The design process begins with downloadable CAD materials and customer specifications, leading to rapid prototyping using a Flow waterjet machine. Rigorous simulations and performance tests ensure that prototypes meet high standards for temperature, load, speed, and stress, resulting in cost-effective solutions for linear motion applications.

PBC Linear operates a 150,000 square-foot manufacturing facility that provides a wide range of linear motion technologies to a global customer base. The newest state-of-the-art factory building includes over 66,000 square feet of optimized manufacturing space. Innovation is central to PBC Linear, with more than 15 pending patents for products designed to reduce components and improve performance, including the SIMO® process for precise aluminum extrusion. The company supports a 24/7 automated production schedule, featuring advanced CNC machining centers that reduce lead times and costs. Additionally, PBC Linear emphasizes rigorous quality control.
