Thrust cylindrical roller bearings are used to withstand heavy axial loads. They are not easily affected by impact loads, have strong rigidity and small axial installation space. They are mainly used under conditions where the load-bearing capacity of thrust ball bearings is insufficient. Most thrust cylindrical roller bearings have a single-row structure and can only bear axial load in one direction. Whether it is a single-row or multi-row structure, the design is very simple.
The design of the contact line between the rollers and raceways 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 group can be installed separately.
Bidirectional thrust roller bearings can be installed in both directions of the shaft. They can be easily combined with the 811 or 812 series shaft, seat ring, cage roller assembly and a spacer ring.
The usage 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 into ordinary grades. When used with high precision, they can also be processed into P6, P5, P4 and P2 grades of precision.
Thrust tapered roller bearings have a very compact axial structure, can withstand very large axial loads, can also withstand impact loads, and have good rigidity. We produce one-way and two-way thrust tapered roller bearings. The contact profile of the rollers and raceways adopts a logarithmic busbar to obtain better stress distribution and extend the service life of the bearings.
The thrust tapered roller bearing and cage adopt a separate design. The two washers and roller cage components 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 different washers.
One design is that the shaft and seat ring are of the same size, and the shaft seat ring has a tapered raceway and a guide rib. Bearings with this design structure are suitable for applications with very large axial loads, such as drilling equipment or lifting equipment. 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, bearings of this structure can allow a slight eccentricity between the shaft and the bearing seat without affecting the use. Except for a few full complement rollers, the bearings are installed with roller center guide cages.
