Currently the engine turbocharger bearing assembly lubricant serious leak is a motor vehicle with turbocharger long, a direct impact on the life of the engine and traffic

safety.angular contact ball bearings
For the sealing means of the lubricating oil in the bearing assembly on the turbocharger, mostly domestic adopted some measures, such as by improving the gap between the bearing

and the shaft of the turbocharger, so that the gap appropriate reduction and prevent oil leakage, or in the off-axis additional seal ring on the seal, improved oil seals,

labyrinth seal ring device sealed, in short, are the oil intercept program. Over the years more programs have the effect of oil leakage is still not completely eradicated.precision ball bearing

Found that the root cause of the turbocharger oil spill through access to large number of domestic and international information and years of practice and testing, eddy current

generated by the rotation of the negative pressure ca used by the high-speed rotation of the turbine rotor side air followed, so that the bearing assembly lubricant negative

pressure forced the oil seal, ordinary prevention and control measures, no matter how to change the oil seal seal forms, has been unable to eradicate the leakage of the new

structure, a new exhaust turbocharger bearing assembly eradicated eddy negative by increased pressure gas positions pressure phenomenon, completely solve the the turbocharger

oil spill phenomenon, and to ensure the safe and reliable operation of the turbocharger to improve its life.cylindrical bearings
