Spyraflo PTFE composite bronze bearings are an extremely high performance plain bearing. A porous layer of bronze particles is sintered onto a steel backing. A PTFE (polytetreflouroethylene) solid substrate is formed into the porous bronze matrix. During operation, a film of PTFE is transferred to the shaft creating a lubricating film. Continued shaft movement ensures constant presence of PTFE lubricant between the bearing and shaft. Under high loads, the PTFE film performs like a hydrostatic bearing and gives the rare benefit of decreased friction as surface load pressure increases.

This product is a great choice for applications with slow to moderate speeds and loads. Our online WearLife calculator can help you to evaluate the service life. Many designers find this bearing offers an unbeatable combination of cost, performance and long service life for slow speed high load applications. Our PTFE composites are chemically resistant to water, alcohol, glycols and mineral oils and is suitable for applications which are dirty/dusty and are resilient to shock loads.
