introduction of national standards

Since the thrust tapered roller bearings rolling body is tapered roller, rolling in the structure of the bus and the bus were raceway washers intersect at a point on the bearing axis line, and thus can form pure rolling rolling surface , speed limit higher than thrust cylindrical roller bearings.
Since thrust tapered roller bearing production is less, the plant has produced models are mostly nonstandard dimensions, while the standard dimensions of the series, varieties produce less, so there is no kind of Cylindrical roller bearing dimensions introduction of national standards.

Design and Installation
With cage LYTBZ 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 bearing screw fixed together by a special positioning components, in order to simplify the operation, the washer on the threaded bolt holes for lifting. See the following description:
Thrust tapered roller bearings
One, a small one-way thrust tapered roller bearings almost exclusively for commercial vehicle steering knuckle bearing configuration. The roller bearings are filled with thin steel cover fixed. Most of these bearings is equipped with wear-resistant, oil resistant nitrile rubber (NBR) friction seals. This multi-purpose grease for bearings lubricated for life, no maintenance. There are a variety of designs, differing only in the bearing housing and the bearing seat cover design.
Larger size produce different way bearing washers; several bearings and bearing housing gasket seat coaxial exactly the same size, while others bearing washers of different design.
Coaxial and bearing housing with dimensions identical seat washer has a tapered raceways and a positioning wall. This design of the bearing is often used to bear large axial load applications, such as drilling equipment used on the dial or crane hook. Such bearings with a cage, through two washers positioning.
Other design of the bearing shaft washer with conical raceway and positioning ribs, while bearing box seat ring is planar (flat) for. Therefore, this design of the bearing to accept the shaft relative to the bearing housing bore slightly eccentric bearing performance without adversely be affected. In addition to several dimensions with full roller, this kind of bearing are concentric with the roller cage
