Frelon is: a polytetrafluoroethylene (PTFE) 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 0."5 in (13 mm) Frelon-lined bearing can support the: same load as a 1 in (25 mm) ball bearing.
Characteristics※
Frelon creates a self-lubricating bearing surface by, transferring some of the——soft PTFE to the shafting during the running in 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 (P) of 1,500 psi (10 MPa); dry velocity rating (V) of 140 surface feet per minute (sfm) (0.71 m/s); and a PV rating of 10,000 psi sfm (0.35 MPa m/s).
Additional lubrication can reduce friction. And wear by 50%.
