Tapered roller bearings can be separated from the inner ring with roller cage with the composition of the components and the outer ring can be installed separately. The correction roller and raceway contac t at the line of contact can reduce the stress concentration. Tapered roller bearings can withstand large radial and axial load. Therefore, in order to pass the opposite direction of the axial load another with mounted symmetrically tapered roller bearings tapered roller bearings can only pass a one-way axial load,.precision bearing

Tapered roller bearings in the largest amount of single row tapered roller bearings. Sedan front wheel hub in recent years, gained access to the small size of the double-row tapered roller bearings. Four-row tapered roller bearings used in large-scale cold and hot rolling mill heavy machinery.

Single row tapered roller bearings have an outer ring, inner ring and a set of tapered roller box-type cage cover into an inner ring assembly. Outer ring and the inner ring component separation, in accordance with ISO Tapered roller bearings Dimensions standard pr ovisions, any one of the standard models of tapered roller bearing outer or inner components and outer ring of the same model or inner components achieve internationally swap. The outer ring of the same type, except the Ministry of size, tolerances subject to ISO492 (GB307) provisions, and the cone angle of the inner components, component cone diameter must also comply with the relevant provisions of the swap.roller ball bearings

Typically, single row tapered roller bearing outer ring raceway cone angle of 10 ° ~ 19 ° before, able to withstand the combined effects of the bearings and radial loads. The larger cone angle the greater the axial load capacity. Large cone angle of bearing rear the code plus B, cone angle between 25 ° ~ 29 °, it can withstand large axial load. In addition, the size of single row tapered roller bearing clearance can be adjusted during installation.

Double row tapered roller bearing outer ring (inner ring) is a whole. The two inner (or outer) face similar small, intermediate spacer, clearance by the thickness of the spacer to adjust, can also be used to adjust the spacer thickness double row tapered roller bearing pre-interference.spindle bearings

Tapered roller bearings mainly bear radial mainly radial and axial joint load. The greater the load carrying capacity depends on the outer ring raceway angle, angle the greater carrying capacity. This kind of bearing is separable bearing, according to the number of columns of the rolling element bearings are divided into single row, double row and four-row tapered roller bearings. Single row tapered roller bearing clearance to adjust installation; Double row and four-row tapered roller bearing clearance has been given based on user requirements in the factory and do not need the user to adjust.

Tapered roller bearings have tapered inner and outer ring raceway, Tapered Roller arranged in between. All conical surface projection lines in the bearing axis of the same point together. This design makes tapered roller bearings particularly suitable to withstand complex (radial and axial) load. Most of the axial load bearing capacity is determined by the contact angle α; α greater the angle, the higher the axial load capacity. The angular size of the calculation of the coefficient e; e higher the value, the greater the contact angle, the bearings are subjected to axial load greater applicability.

Tapered roller bearings are usually separated type, that is, from the inner ring with roller and cage assemblies consisting of tapered inner components can be installed separately with the the cone outer ring (outer ring).

Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery industry.
