typical application
JF-800 bimetal bearing (universal type) is mainly used in medium-load medium-speed oil lubrication or grease lubrication. Typical applications include engine connecting rods, pin shafts, engineering machinery chassis rollers, carrier rollers, guide wheels, hydraulic cylinder guide sleeves, oil earrings, logistics machinery, and agricultural machinery. Since the sintered copper alloy layer contains lead, the use of this product under certain conditions will be limited according to relevant laws and regulations.
