The four versions of the Oscimax® brand of machinable self-lubricating liner technology include the original long-life version (XT), two low friction options (XY and XZ), and a specific formulation for landing gear applications (XG). Below are brief descriptions of each unique solution:
The original formulation designed principally to overcome life limiting factors.
When it comes to wear-resistance and operating life, Oscimax 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.
This first of two reduced-friction options achieves superior life compared to competing solutions.
Oscimax XY 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.
Designed with extremely low friction properties, XZ is 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.
Specially formulated to provide just the right performance for landing gear applications.
The unique properties of Oscimax 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.
