High Precision Miniature Tapered Roller Bearings , Single Row Or Double Row Or Four Row
Tapered roller bearings are mainly suitable to carry combined
load--- radial load and as well as axial load; while steep angle
tapered roller bearings (27°-30°) can carry the combined load
dominated by the axial load. The tapered roller bearings are
separable bearings, their internal assemblies and outer rings can
be mounted separately; the radial clearance and axial clearance
cane be adjusted when mounting and clearance fits are also allowed.
Structures
1. 30000 type single-row tapered roller bearings
This type of bearings can accommodate the axial displacement and axial load on one direction on the shaft or housing. An additional axial force will be generated under the action of radial load, so the outer ring and inner ring inside the two bearing slewing should be mounted with their end faces with same name opposite each other. When applied separately, the applied axial force must be larger than the additional axial force.
2. 350000, 37000 and 87000 types of double-row tapered roller bearings
These types of bearings comprise one double-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 outer rings), to change the thickness of the spacer can adjust be bearing clearance. They can carry radial and double-direction axial load simultaneously.
3. 380000 type four-row tapered roller bearings
This type of bearings adopts two double-raceway inner rings, one double-raceway outer rings and two single raceways. There are spacers between inner rings and outer rings used for adjusting bearing clearance. They can accommodate large radial load. But their limit rotational speed is low so they are mainly applied to heavy-duty machines such as rolling mills.
