Polymer Bushing Bearings

Polymer Bushing Bearings

Thomson polymer bushing bearings offer linear motion designers a reliable, yet economical, option for machines in which moment load is non-critical or contamination and temperature are concerns. These plain bearings are also useful for applications that require shafting that is incompatible with traditional Ball Bushings® (e.g. 316 stainless steel). Handling loads up to 2023 lbf, polymer bushings provide a corrosion-resistant option for low-load, low-speed applications.

When combined with roundrail shafting, pillow blocks or other assembly components, polymer bearings deliver a cost-effective linear motion solution to a number of applications, including factory automation, robotics, health and fitness, medical automation, woodworking, packaging, food and beverage, and vending.
