TaperedRoller Bearings Tapered roller bearings are mainly suitableto carry combined load---radial load and as well as axial load; While steepangle tapered roller bearings (27-30) can carry the combined load dominatedby the axial load. The tapered roller bearings are separable bearings, theirinternal assemblies and outer rings can be mounted separately; the radialclearance and axial clearance can be adjusted when mounting and interferencefits are also allowed. Structures 1.30000type single-row tapered roller bearings This type of bearings can accommodate theaxial displacement and axial load on one direction on the shaft or housing. Anadditional axial force will be generated under the action of radial load, sothe outer ring and inner ring inside the two bearing slewing should be mountedwith their end faces with same name opposite each other. When appliedseparately, the applied axial force must be larger than the additional axialforce. 2.350000and 370000 types of double-row tapered roller bearings These types of bearings comprise onedouble-raceway outer ring (one double-raceway inner ring) and two inner rings(two outer rings). There is a spacer between the two inner rings (two outerrings), To change the thickness of the spacer can adjust the bearing clearance.They can carry radial and double-direction axial load simultaneously. 3.380000 type four-row tapered roller bearings This type of bearing adopts twodouble-raceway inner rings, one double-raceway outer rings
