Frequently Asked Questions

Self-lubricating bushings contain embedded solid lubricants like PTFE or graphite that gradually transfer to the mating surface, reducing friction without requiring external oiling.

Yes, many of our bushings (like SF-1 and DX series) are designed for oil-free or maintenance-free operation under boundary lubrication conditions.

A bimetal bushing consists of a steel backing with a sintered bronze or lead-bronze lining. It offers high load capacity and is typically used in oil-lubricated environments.

Yes, we offer lead-free variants such as SF-1W, SF-2Y, and SF-2L for environmentally sensitive applications.

Our products are widely used in construction equipment, agricultural machinery, hydraulic systems, gear pumps, and industrial automation.
