HERO BEARING CO., LIMITED Double outer double row tapered roller bearings are radial thrust roller bearings with tapered rollers. There are two kinds of small cone angle and large cone angle Bearing 160TDI270-2. The Bearing 160TDI270-2 small cone angle mainly bears the radial and axial combined load mainly based on radial load. Double outer double row tapered roller bearings is usually used in double use and reversed installation. The Bearing 160TDI270-2 inner and outer races can be separately installed. The Double outer double row tapered roller bearings radial and axial clearance can be adjusted during installation and use. The large cone angle is mainly subjected to the combined axial and radial loads mainly due to axial load. Generally, Bearing 160TDI270-2 is not used alone to bear the pure axial load. When paired configuration (relative to the end of the same name) can be used to bear the pure radial load. The ability of a single row tapered roller bearing to withstand axial loads depends on the contact angle, that is, the Double outer double row tapered roller bearings outer ring raceway angle. The larger the angle, the greater the axial load capacity. The largest amount of tapered roller bearings is single row tapered roller bearings. In the front wheel hub of the car, a small-sized double-row tapered roller bearing was used. Four-row tapered roller bearings Double outer double row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.
Tapered roller bearings are mainly subjected to radial and axial combined load. The bearing Bearing 160TDI270-2 capacity depends on the raceway angle of the outer ring. The larger the angle, the greater the bearing capacity. This type of bearing is a separate type bearing and is classified into single row, double row and four row tapered roller bearings Bearing 160TDI270-2 according to the number of rows of rolling elements in the bearing. The single-row tapered roller bearing clearance needs to be adjusted by the user during installation; the double-row and four-row tapered roller bearing clearance is already specified according to the user's requirements at the time of delivery, without user adjustment. Tapered roller bearings have a conical inner ring and an outer ring raceway with tapered rollers arranged in between. The projection lines of all cone surfaces converge at the same point on the bearing axis. This design Double outer double row tapered roller bearings makes the tapered roller bearing particularly suitable for supporting composite (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α; the larger the α angle, the higher the axial load capacity. The size of the angle is expressed by the calculation coefficient e; the greater the value of e, the greater the contact angle, the greater the suitability of the bearing to withstand the axial load. Tapered roller bearings are usually of a separate type, ie a cone inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from the outer ring of the cone.
Bearing 160TDI270-2 are widely used in automotive, rolling mills, mining, metallurgy, plastics machinery and other industries.
