Solid graphite is the lubricant here — no oil, no grease. Graphite Bronze Washers combine premium-grade bronze with integrated solid graphite, delivering continuous, self-lubricating performance in demanding industrial applications. The result is smooth operation and excellent wear resistance without any need for external lubrication.
The graphite itself does the heavy lifting: it acts as a solid lubricant, reducing friction and minimizing wear between contact surfaces, even under high loads and elevated temperatures. That makes these washers a strong choice anywhere regular lubrication is difficult or simply not feasible.
We build every graphite bronze washer for strength, durability, and precision. So they hold up reliably in harsh working environments, with consistent efficiency and a long service life.
