Rolled Bronze Bushing Sliding Bearing with Oil Hole and Oil Grooves, Special Designed Split Bronze Bearing
ZR-092 Bronze bushings are Suitable for MBB-Palfinger.The bearings are manufactured of a cold formable homoge-nous bronze, which because of this will obtain exceptional material pro-perties. The standard sizes are fitted with holes, which are dispersed in a special way over the whole bearing-surface.
These holes with sepcial designed oil grooves serve as lubricant reservoirs i.a. to rapidly build up a lubrication film in the moment of start and therewith reduce the start friction.
