Your Partner for High-Precision Bearing Cages and Customized Solutions
We manufacture a wide range of engineering polymer, hybrid and phenolic resin precision bearing cages for use in machine spindle bearings and other demanding applications. These cages are lightweight, low-friction, and dimensionally stable. Even at high speeds, they generate minimal heat. As a result, engineering polymer, hybrid and phenolic resin precision bearing cages are on par with those made of steel or aluminium. The range of applications extends from machine tools—such as lathes and milling machines—to dental drills.
We produce bearing cages through both machining of our in-house tubes and high-performance moulding, enabling us to meet the demands of high-volume production and specialised applications alike. With full control over material production, machining, and moulding, our in-house capabilities ensure consistent quality, tight dimensional tolerances, and reliable execution of customer designs.
We also support customers who manufacture their own cages by supplying post-processed tubes in a wide range of sizes and specifications.
