Tapered roller bearings mainly bear radial diameter, axial joint load. Load bearing capacity depends on the outer ring raceway angle, angle the greater carrying capacity. These bearings are separable bearings, according to the number of columns bearing rolling elements into single row, double row and mobile crane bearing four row tapered roller bearings. Single row tapered roller bearing clearance to be user adjusted during installation; double row and four row tapered roller bearing clearance in the factory based on the given user requirements, users do not need to adjust.
Tapered roller bearings have tapered inner and outer ring raceways, tapered rollers are arranged between the two. All conical surface projection lines are a little get together with the bearing axis. This design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. Most of axial load bearing capacity is determined by the contact angle α; greater the α angle, the higher the axial load capacity. crossed roller bearings Angle size to calculate the coefficient e; e value, the greater the contact angle, the bearing axial load greater applicability.
Tapered roller bearings are usually separated type, that is with roller and cage assembly of components of the inner cone and cone outer (outer) installed separately.
