Self lubricating bearing lined with PTFE fabrics takes woven Teflon or PTFE fibers as friction surface with applied to the steel base with structure adhesives. To assure the best possible bond between PTFE fibers and backing steel material, a kind of polyamide fibers is interwoven with the PTFE fibers.
These bearings are the most suitable for following applications: high loads, lower speed. They are usually used in equipment as follow: Guidevance bearing, ball valve and butterfly valve of hydro-power station; Heavy-duty suspension systems of trucks, tractors, fork lift trucks and related equipment, for example rock shaft assembly, steering system, brake system, clutch for trucks, passenger cars, farm machinery, outboard motor steering system, butterfly valve and ball valve, conforms to NSF standard, extile machinery, Bridge, pipe lines, and other structure supporting bearings, cranes boom foot pivot, hinge and brace points in the pendants assembly.
