sell 4-rows taper roller bearing 20090424

The inner ring with rollers and cage constitutes components, which can be assembled with outer ring separately. The bearing is mainly used for bearing radial, axal combined load with radial load in the main. the bearing capability of bearing axial load depends on the contact angle, the bigger the contact anglees, the bigger the bearing capacity will be. The tapered roller bearing doesn't allow inclination of the shaft to the housing. The size of axial clearance has much to do with normal cperation of the bearing. When the ciearance is too small, the temperature rises higher and the clearance is excessively big, the bearing is apt to damage. So while mounting, special attention should be paid to the good adjustment of the axial clearance of the single row tapered roller bearing. the clearances of the double row and four row bearings are set before products leave factory. Customers don't need to make adjustment.
