The modified design of Double Row Spherical Roller Radial Bearings provides the increase of the reliability and serv life of the bearing units by 10 %... 15 % in the actual operating conditions.
The increase of the consumer characteristics of MPZ brand bearings is stipulated by:
-brass cage design modification;
-the modified ring raceway contact with the rollers;
-manufacturing only from vacuum steel.
In roller spherical bearings a cage keeps the rollers separated from each other and properly guides them in the nc loaded area and in the loaded area input.
The modified design of Double Row Spherical Roller Radial Bearing due to the cage width increase and vacuum si application allows:
-to increase the service life;
-to increase the roller coverage in the cage window;
-to eliminate the contact of the roller element with the cage tooth edge that results in the wear reduction of the cage bars The bearing design modification doesn't involve the changes in the mounting characteristics and doesn't cause any changes usual bearing mounting practice and operation.
