Self-Lubricating Bearings


Our self-lubricating liner systems have been utilized in Formula One, Indy, and Rally Cars for several decades, offering high performance, long life, and reliable bearing solutions in critical steering, suspension, and other automotive system locations. Whether the bearings utilize our high-performance KAron machinable liner system or our industry-leading Fraslip fabric liner system, each solution can be tailored to your specific application needs.

Our onsite, full service Test and Development Lab can support most development or qualification tests that may be needed for your application. If your test requirements fall outside of our internal capabilities, we can utilize our network of trusted, third party test facilities to provide the performance data that you require.
