Sauer 90R55 Hydraulic Pump Bearings 307 Nup Cylindrical Roller Bearing

Product detail:

The most important component of the plunger pump is the bearing. If the bearing has clearance, the normal clearance of the three pairs of friction pairs inside the hydraulic pump cannot be guaranteed. At the same time, it will also destroy the thickness of the hydrostatic support oil film of each friction pair and reduce the bearing of the plunger pump. Service life, according to the information provided by the hydraulic pump manufacturer, the average service life of the bearing is 10000h. If it exceeds this value, it needs to be replaced with a new port. The disassembled bearing cannot detect the clearance of the bearing without professional testing equipment. If you use visual inspection, if you find scratches or discoloration on the surface of the roller, you must replace it. When replacing the bearing, you should pay attention to the original English letter and model number. The plunger pump bearings mostly use large load capacity bearings, and it is best to buy The original manufacturer, the original specifiions of the product, if you change another brand, you should consult a person who is experienced in the extraction of the table to exchange, the purpose is to maintain the accuracy level of the bearing and the cutting capacity
