Single-row tapered roller bearings have an outer ring, the inner ring and a set of tapered roller cage by the basket-shaped into an inner component. The outer ring can be separated from the inner ring assembly, in accordance with the ISO tapered roller bearing size standards, any standard type of tapered roller bearing outer ring or inner ring components and the same type of outer or inner components should be international exchange. That is the same type of outer ring in addition to external dimensions and tolerances to be in accordance with ISO492 (GB307) requirements, the inner ring component cone angle, component cone diameter must also meet the relevant provisions of the swap.
Usually, the single row tapered roller bearing outer ring raceway in the cone angle of 10 ° ~ 19 ° before, can simultaneously bear the axial load and radial load of the joint role. The greater the cone angle, the greater the ability to withstand axial loads. Large cone angle bearings, post code plus B, cone angle between 25 ° ~ 29 °, it can withstand a larger axial load. In addition, single row tapered roller bearings can be installed during the adjustment of the size of the clearance.
Double row tapered roller bearing outer ring (or inner ring) is a whole. Two inner (or outer) small end similar to the middle of a circle, the clearance is by the thickness of the spacer to adjust, but also can be used to adjust the thickness of the double row tapered roller bearings pre-surplus.
Four row tapered roller bearings, the performance of such bearings and double row tapered roller bearings are basically the same, but double row tapered roller bearings to withstand the radial load greater limit speed is slightly lower, mainly for heavy machinery, such as Rolling mill and so on.
