Tapered roller bearings with radial oriented mainly to bear radial and axial joint load. Bearing load capacity depends on the angle of the outer ring raceway, the greater the angle the greater the carrying capacity. This kind of bearing is separable bearings, rolling bearings according to the number of rows into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance adjustment required to the user during installation; double row and four row tapered roller bearing clearance from the factory has been given based on user requirements, users do not need to adjust.
Tapered roller bearings have tapered inner and outer ring raceways, tapered roller arranged between the two. The surface of the projection lines of all cone bearing axis in the same point together. This design makes tapered roller bearings particularly suitable for bearing complex (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle α; α angle increases, the higher the axial load capacity. Angle size of the computational coefficient e to represent; e greater the contact angle the greater the bearing axial load greater applicability.
Tapered roller bearings are usually separated type, that is, with roller and cage assembly of the inner components of the composition of the inner cone with tapered outer (outer) installed separately.
Tapered roller bearings are widely used in automotive, mill, mine, metallurgy, plastics and machinery.
