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 run-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 ; 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%.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Frelon (material)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
