Plain Bearings
A plain bearing may be simple, but when our self-clinching and self-aligning features are added, plain bearings become dynamic problem solvers. Comprised of a bearing surface with no rolling elements, these journal bearings are compact, lightweight and can carry high loads. Excellent for moderate-load, high-speed applications, these bearings offer an extremely effective means of radial support.
Available in press-fit, self-clinching or mounted configurations, with or without Spyraflo’s patented self-aligning feature. Available materials include bronze, acetal and PTFE-composite bronze.
