Bearing 2rs stands for double adhesive film seal

Bearing 2rs stands for double adhesive film seal, RS for contact seal (rubber seal).Deep groove ball bearings include one side with dust cover, two sides with dust cover, one side with seal ring, two sides with seal ring, outer ring with stop groove, outer ring with brake ring and stop groove, double row deep groove ball bearings.
Bearing 2rs means deep groove ball bearings with sealing rings or dust caps on both sides have been filled with grease for lifelong lubrication without maintenance.The deep groove raceway and excellent compacting degree between the raceway and the steel ball make the Wuxi Trine deep groove ball bearing can bear not only radial load but also bidirectional axial load even under the condition of high speed.
Application for bearing 2rs:
Bearing 2rs are widely used in transmission, instrumentation, electrical, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, yo-yo, printing, textile, automobile, etc.
How to assemble bearing 2rs?
Heating cooperates: the bearing 2rs by heating, the use of thermal expansion will fit into a loose fit method of installation.. This method is suitable for interference quantity larger the installation of the bearing 2rs, the bearing before hot charging type or separable bearing ring into the fuel tank even heat 80-100 ℃, and then loaded on the shaft, as soon as possible out of the oil to prevent inner ring after cooling end face and the shoulder joint is not tight, to axial bearing cooling can then tighten.
Bearing 2rs outer ring and light metal bearing seat tight fit, by heating the hot charging method of the bearing, can avoid the mating surface scratch.Heating tank with bearing 2rs and should be at a certain distance from the bottom of a mesh, or hanging hooks in the bearings, bearing on the bottom, in case of heavy impurities into the bearing or uneven heating, fuel tank must have a thermometer, strictly control the oil temperature shall not exceed 100 ℃, in order to prevent the tempering effect, reduce the hardness of the ring.
