BK OILON (green) (PA6 + oil)
The internally lubricated cast nylon 6 self-lubricating in the real meaning of the word. BOBKAY OllON, especially developed for unlubricated, highly loaded and slowly moving parts applications, yields a considerable enlargement of the application possibilities of nylons. This is because of its reduced coefficient of friction (up to - 50 %) and improved wear resistance (up to x 10).
