Use of WSBC Tapered Roller Bearings

Tapered roller bearings mainly bear radial and axial combined load.Bearing capacity depends on the raceway Angle of the outer ring, and the larger the Angle, the greater the bearing capacity.The bearings are separable bearings, which are divided into single column, double row and four row tapered roller bearings according to the number of rolling bodies in the bearing.Single row tapered roller bearing clearance needs to be adjusted by users during installation;Double row and four row tapered roller bearing clearance has been given to the user according to the requirements of the user, without user adjustment.Wuxi Spark Bearing Co.,Ltd has enough stock for tapered roller bearings.

Tapered roller bearings have conical inner ring and outer ring raceway, and the taper roller is arranged between the two.The projection lines on all conical surfaces meet at the same point on the axis of the bearing.This design makes tapered roller bearings especially suitable for bearing composite (radial and axial) loads.The axial load capacity of bearings is mainly determined by contact Angle.The larger the Angle, the higher the axial load.The Angle is represented by the calculation coefficient e;The larger the value of e, the greater the contact Angle, the greater the applicability of bearing axial load.Tapered roller bearings are usually separated, i.e. the inner ring components of the roller and the inner ring of the cage assembly can be separately installed with the cone outer ring (outer ring).

Tapered roller bearings have tapered inner ring and outer ring raceway, and tapered rollers are arranged in between.All the projection lines on the cone surface meet at the same point on the bearing axis.This design makes tapered roller bearings particularly suitable for composite (radial and axial) loads.The bearing axial load capacity is largely determined by the contact Angle.The greater the Angle, the greater the axial load capacity.The magnitude of the Angle is expressed by the calculated coefficient e;The greater the e value, the greater the contact Angle, and the greater the applicability of the bearing to bear the axial load.Need WSBC Single row inch size tapered roller bearings LL957049/LL957010 click here.

Tapered roller bearings are usually of the separate type, that is, the tapered inner ring assembly consisting of the inner ring with the roller and cage assembly can be mounted separately from the tapered outer ring (outer ring).

The ability of a single row tapered roller bearing to bear axial load depends on the contact Angle, that is, the raceway Angle of the outer ring. The greater the Angle, the greater the axial load capacity.Tapered roller bearings in the largest amount of single row tapered roller bearings.In the front wheel hub of the car, a small size double row tapered roller bearings are used.Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.

Adjustment axial clearance for the installation of axial clearance of tapered roller bearings, adjustment can be made by means of adjusting nuts on the journal, adjusting gaskets and threads in bearing seat holes, or by means of pre-tightening springs.The size of the axial clearance is related to the arrangement of the bearing when it is installed, the distance between the bearings, and the material of the shaft and the bearing housing, which can be determined according to the working conditions.

For tapered roller bearings with high load and high speed, the influence of temperature rise on axial clearance must be considered when adjusting clearance, and the clearance reduction caused by temperature rise must be estimated. In other words, the axial clearance should be appropriately adjusted to be larger.

For bearings with low rotational speed and bearing vibration, they shall be installed without clearance or preloaded.The purpose is to make the roller and raceway of tapered roller bearing have good contact, the load is evenly distributed, prevent the roller and raceway from being damaged by vibration impact.After adjustment, the axial clearance size is checked by micrometer.

Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
