Product Details:
- Dry lubricant bearings feature steel backing for high-strength and high load capacity, and a PTFE impregnated bronze inter-layer to provide a strong mechanical bond for the lining. While running under normal conditions, a thin layer of PTFE lining is transferred to the opposing surface which stays there and helps in reducing friction. These bearings can easily operate at temperatures ranging from -328 to 536 degrees Fahrenheit.
