BR8 series products
BR8 steel cast copper self-lubricating bearing
BR8 steel cast copper self-lubricating bearing is a solid lubricating product embedded with solid lubricant after the overall sintering of tin bronze powder in the base of the steel sleeve. In addition to the function of BR51, it can save costs and improve the compressive strength.
Its end face can be welded with the substrate for installation and use, so it is suitable for metallurgical machinery, construction machinery, oil transmission machinery and other fields that cannot be refueled.
