Frelon (material)
Frelon is a polytetrafluoroethylene based material with other proprietary fillers to increase bearing characteristics, such as low wear, low friction, and high strength. It is chemically inert and self lubricating. It qualifies as a class III plain bearing. The load capacity of a frelon-lined bearing is typically four to eight times that of a comparable ball bearing; for instance, a Frelon-lined bearing can support the same load as a ball bearing.Characteristics
Frelon creates a self-lubricating bearing surface by transferring some of the soft PTFE to the shafting during the process. It is almost universally chemically inert; the only materials that attack it are molten sodium and fluorine at elevated temperatures.
It has a plain bearing pressure rating of ; dry velocity rating of 140 surface feet per minute ; and a PV rating of 10,000 psi sfm.
Additional lubrication can reduce friction and wear by 50%.
