Classification Of Double Row Tapered Roller Bearings
The outer ring (or inner ring) of a double row tapered roller bearing is a whole. Two inner ring (or outer ring) small end face close, in the middle of a ring, the clearance is adjusted by the thickness of the ring, can also be used to adjust the thickness of the two-row tapered roller bearings of the pre-surplus.
Four row tapered roller bearings, the performance of such bearings and double row tapered roller bearings are basically the same, but more than the double row tapered roller bearings under the radial load, the limit speed is slightly lower, mainly used in heavy machinery.
Multi-Seal double, four row tapered roller bearings, zwz provide long life, multiple sealed double, four row tapered roller bearings. The new design of bearing is personalized, the traditional design method of fully sealed bearing is changed, the sealing effect is improved and the sealing performance is improved by adopting the new type of sealing structure with the combination of seal and dust-proof. Multi-Seal double, four row tapered roller bearings and open-type structural bearings compared to the life of $number, lubricant consumption reduced by 80%.
