Bi-directional thrust tapered roller bearings

Bi-directional thrust tapered roller bearings are mainly in the steel rolling machine with multi-row cylindrical roller bearings used together. This shaft washer with flat bearing more popular, because this
  Bi-directional thrust tapered roller backing bearings
Bearings can withstand the shaft relative to the bearing housing bore slightly eccentric, as well as radial bearings radial internal clearance slightly. In the two bearing housing seat is equipped with an interval between sets. Spacers size makes roller bearing box cover screw is fully tightened, but bearing no special spring adjustment.
Shaft and housing seat with conical raceway bidirectional tapered roller thrust bearings. Generally lower than with the axes of the plane of the bearing seat with high axial load bearing capacity, and to a certain extent, radial positioning of the shaft. If we consider the desired service life, this bearing load carrying capacity is insufficient, you can use the contact angle of TDIS designed double row tapered roller bearings, see "double row tapered roller bearings."
Since Bi-directional thrust tapered Roller bearing are usually in the roll journal and roller bearing housing to loosely fitted, most bearing shaft seat one or two locating slots. This makes it possible to use embedded positioning groove key or similar means to prevent rotation of the shaft axis seat.

Third, this type of thrust tapered roller bearings must be able to withstand enormous axial load, and allows the threaded shaft angular displacement relative to the support. Therefore, these bearings usually full roller type, with large diameter and long rollers. In order to withstand the roll offset in the bearing housing on the bearing not adversely affect the performance of this bearing has a spherical seat. The seat can be a shaft or bearing seat box seat.
In the spherical shaft seat and the corresponding concave spherical threaded shaft or pressure roller between the baffle set above a spherical seat of the bearing axis, will produce the necessary right of offset. LYTBZ can also supply the pressure plate.
Spherical bearing box seat when the offset from the bearing housing on the seat between the baffle and the pressure roller groups to bear. This bearing pressure plate is usually supplied with the same bearing.
LYTBZ produce a variety of designs screw bearings; This bearing is customized to meet the special requirements of a particular application
