Introduction of Thrust Cylindrical Roller Bearings

Thrust cylindrical roller INA bearings are used to withstand heavy axial loads and are not easily affected by impact loads. They have strong rigidity and small axial installation space. They are mainly used under conditions of insufficient load carrying capacity of thrust ball bearings. Most thrust cylindrical roller bearings are of single-row structure and can only bear axial load in one direction. The design of either single-row or multi-row structure is very simple.

The design of the contact line between the roller and the raceway of all thrust cylindrical roller bearings is optimized to avoid edge effects. Moreover, the bearings are of separate structure, and the shaft, seat ring and cage roller set can be installed separately.

Two-way thrust roller bearings can be installed in both directions of the shaft, and it is very convenient to use the 811 or 812 series shaft, seat ring, cage roller assembly and a spacer ring combination.

The operating conditions of thrust cylindrical roller bearings do not allow any angular deviation and eccentricity between the shaft and the bearing seat.

Thrust cylindrical roller bearings are usually processed to ordinary grade, and can also be processed to P6, P5, P4 and P2 precision when used in high precision.

Thrust tapered roller bearings have a compact axial structure and can withstand very large axial loads as well as impact loads with good rigidity. We produce one-way and two-way thrust tapered roller bearings. The contact profile of the roller and the raceway adopts a logarithmic bus to obtain a better stress distribution and prolong the service life of the bearing.

The thrust tapered roller bearing and the cage adopt a separate design, and the two washers and the roller cage assembly can be installed separately, which is very simple. The one-way thrust tapered roller bearings we produce are divided into two design structures due to the difference of washers.

One design is that the shaft and the seat ring have the same size, and the shaft seat ring has a tapered raceway and a guide rib. The bearing of this design structure is suitable for very large axial loads, such as drilling equipment or lifting equipment, and the roller cage is installed in the center of the washer.

Another design is that the shaft ring has tapered raceways and ribs, and the seat ring is flat. Therefore, the bearing of this structure can allow the shaft and the bearing seat to have a slight eccentricity without affecting the use. Except for a few full complement rollers, the bearing installation is the roller center guide cage.
