Titanium

In applications that require low overall weight, titanium alloy is a popular choice for bearing material. For years customers using these bearings struggled with the fact that at very high bearing loads (such as those specified in AS81820), titanium alloys tend to exhibit less-stable dynamic friction coefficients. Titanium alloy bearings can also be subject to surface distress (wear scarring of the titanium). Using a diffusion-hardened Ti64 mating surface within self-lubricating bearing systems, KAMAN Specialty Bearings & Engineered Products has been able to alleviate wear scarring, providing customers with a solution for highly efficient, high load, lightweight bearings.
