This type of bearing is used to bear heavier radial-axial combined loads with limit rotational speeds higher. The bearings are mainly applied to the construction parts that limit axial displacement of the axis or housing in double directions.
The bearing is used with four row cylindrical roller bearings limiting the axial motion of roll in rolling mill the axial load capactiy is heavier than four-point contact ball ebearings incomparison with paiy mounted in back-to-back, face-to-face arvangements single row angular contact ball bearings units, the axial clearance of the bearing doesn't need adjustment, these bearings can be mounted with ease and there can be two types: two half-outer-rings and two half-inner-rings according to the installation need of customers.
Tapered roller bearings mainly bear radial combined load in diameter and axial direction. Bearing bearing capacity depends on the outer ring raceway Angle, the greater the Angle bearing
The greater the carrying capacity. This kind of bearing belongs to separate type bearing, which can be divided into single row, double row and four row tapered roller bearings according to the number of rolling body in the bearing. Clearance of single row tapered roller bearing shall be adjusted by the user during installation; The clearance of double-row and four-row tapered roller bearings has been given according to the customer's requirements when the product leaves the factory, and it does not need to be adjusted by the customer.
Tapered roller bearings have a conical inner ring and an outer ring raceway, with tapered rollers arranged in between. All projection lines on the conical surface meet at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing combined (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact Angle a. The greater the alpha Angle, the higher the axial load capacity. The Angle is expressed by the calculation coefficient e; The larger the e value, the larger the contact Angle, the greater the applicability of bearing bearing axial load.
Tapered roller bearings are usually separable, i.e., a tapered inner ring consisting of an inner ring of the roller and retainer assembly may be mounted separately from the tapered outer ring (outer ring).
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
