Introduction Of Taper Roller Bearing

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 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 ; greater the angle, the higher the axial load capacity. Angle size to calculate the coefficient e; e value, the greater the contact angle, the bearing axial load greater applicability.
