Oscimax® Now a Family of Machinable Liner Solutions

Back to Press Releases


March 25, 2014 (Laconia, NH) - NHBB has developed and launched three new versions of the Oscimax® brand of machinable self-lubricating liner technology which, along with the original version, Oscimax XT, now covers the full range of friction and life requirements for NHBB's aerospace customers. The new versions include two low friction options (Oscimax XY and XZ) and a specific formulation for landing gear applications (XG).

Oscimax XT is the original formulation designed principally to overcome life limiting factors. When it comes to wear-resistance and operating life, XT outperforms fabric-based PTFE liners and performs exceptionally well compared to other machinable, self-lubricating liner solutions. Independent lab tests have verified that XT exceeds all performance requirements of AS81934 beyond 100,000 cycles. At room temperature and a load of 37.5 ksi, XT exhibits 0.0005 in. of wear at 100,000 cycles, and its coefficient of friction is between 0.11 and 0.05. Even more impressive are the results of tests conducted at room temperature with no contaminants: Oscimax XT exhibited liner wear rates under 0.004 in. at one million cycles.

Oscimax XY, the first of two reduced-friction options, has a lower coefficient of friction than XT but superior wear resistance and life than equivalent reduced-friction liners on the market today. At room temperature with a load of 37.5 ksi, the XY liner exhibits approximately 0.0027 in. of wear at 100,000 cycles, and its coefficient of friction is between 0.09 and 0.04. Oscimax XY meets the performance requirements of AS81934.

Oscimax XZ is designed to have extremely low friction properties, which makes it highly suitable for lightly loaded applications. The coefficient of friction for XZ is equivalent to competing solutions but it has a slight to significant advantage in wear and life, depending on the operating conditions. At room temperature with a load of 16 ksi, the XZ liner exhibits 0.0020 in. of wear at 100,000 cycles and its coefficient of friction is between 0.07 and 0.03.

Oscimax XG is specially formulated for landing gear applications. The unique properties of XG allow for a greater finished depth yet this liner still offers reduced friction as well as good wear and life. At room temperature with a load of 16 ksi, the XG liner type exhibits less than 0.0007 in. of wear at 100,000 cycles, and its coefficient of friction is between 0.10 and 0.03.

The Oscimax brand of machinable, self-lubricating liner technology was developed by NHBB to reduce wear, resist corrosion and moisture, and extend the operating life of plain bearings and related next-up assemblies. Thanks to its versatility, the patented technology is utilized as a self-lubricating liner and anti-fretting coating in a wide array of engine and airframe systems, including engine controls, flight control systems, landing gear, access doors and emergency exits, and more.
