Thrust tapered roller bearings 
Thrust tapered roller bearings can be formed axially very compact bearing arrangements, these bearings can withstand heavy axial load, impact load is not sensitive, and good rigidity. WJJC producing unidirectional thrust tapered roller bearings and two-way thrust tapered roller bearings. Tapered Screw-way bearing constitutes a specially designed roller thrust bearings, and contain full roller.

Since the thrust tapered roller bearings in rolling element tapered roller, in the structure of the rolling bus washer raceway bus intersect at the bearing axis are online at some point, so that the rolling surface can form pure rolling, limit speed higher than the thrust cylindrical roller bearings.

Due to less production of thrust tapered roller bearings, the model of the plant has produced more non-standard dimensions, and less standard form factor series, the full production, and thus there is no class bearing dimensions of national standards introduced. The standard view is currently available for GB / T 4663--1994

Design and Installation

WJJC with cage thrust tapered roller bearings for the separation of design, so that the two washers and the roller and cage thrust assembly can be easily installed separately. Full roller bearings made of special positioning screw parts together, in order to simplify the operation, there is a threaded hole for lifting bolt on the gasket.

See the following description:
A small one-way thrust tapered roller bearing arrangements knuckle roller bearings almost entirely for commercial vehicles. This full roller bearings, fixed cover with a thin steel plate. Most of these bearings is equipped with wear-resistant, oil resistant nitrile rubber (NBR) friction seals. This bearing multipurpose grease lifelong lubrication, maintenance free. There are a variety of designs, different from just bearing box seat and bearing cover design.

One-way bearing larger size washers produce different; some of the bearing housing and bearing washers coaxial race exactly the same size and different other bearing washer design.

The same size gasket with concentric rings and bearing box seat has a tapered raceway and a positioning rib. This design is often used bearing to bear large axial load occasions, such as drilling equipment on the dial or use a crane hook. Such bearings with a cage by two washers positioning.

Other designs of shaft washer with tapered roller bearings and positioning ribs, while bearing box seat is flat (level). Thus, the design of the bearing to accept the shaft relative to the bearing housing hole slightly eccentric, without affecting adversely affect bearing performance. Apart from a few rollers with full size, these bearings are roller cage and concentric.

Second, the two-way model thrust tapered roller bearings in rolling mills with multi-row cylindrical roller bearings are used together. This bearing shaft with a flat washer is more popular because these bearings can withstand slightly eccentric shaft relative to the bearing housing hole, and a slight change in radial bearings radial internal clearance. Between the two bearing box seat is equipped with a spacer sleeve. Spacers the size of the roll bearing box cover screw is fully tightened and no special spring adjustment bearing.

Bi-tapered shaft and bearing box seat with tapered raceways roller thrust bearings. Generally higher than the shaft bearing with flat seat has a higher axial load carrying capacity, but also to a certain extent, the shaft radial positioning. If you take into account the required service life, the bearings of the load bearing capacity is insufficient, you can use the contact angle of double row design TDIS tapered roller bearings, see "double row tapered roller bearings."

Since Bi-directional thrust tapered roller bearings are usually in the roll journal and roller bearing box with a loose fit installation, most of the bearing shaft seat has one or two locating slots. This makes it possible to use embedded key positioning groove or the like, to prevent the shaft to rotate the shaft seat.

Third, this type of thrust tapered roller bearings must be able to withstand extreme axial load, and allow the relative angular displacement of the threaded shaft bearing. Therefore, this is usually full roller bearing type, large diameter long rollers. In order to withstand the roll bearing boxes of offset without adversely affecting the performance of the bearing, this bearing has a spherical seat. The seat may be a seat or shaft bearing box seat.

In spherical roller set above the shaft seat and the corresponding concave spherical threaded shaft or pressure between the baffle has a spherical shaft bearing race, will produce the necessary alignment offset. WJJC can also supply the pressure bezel.

When the bearing housing spherical seat of the offset by a roller bearing box seat and pressure between the baffle set to bear. Such bearings are typically supplied together with the pressure bearing bezel.

WJJC produce a variety of design screw bearings; this bearing is customized to meet the specific requirements of a particular application.
