Thrust Roller Bearing
Thrust roller bearing belongs to separated type bearing, which is easy to install and disassemble. The rigidity of the bearing is large, and the occupied space is small. It can bear large axial load and a certain amount of impact load, but the allowable speed of the structure bearing is relatively low.
-
According to the structure, the thrust roller bearing is divided into:
-
thrust cylindrical roller bearing;
-
thrust tapered roller bearing;
-
thrust spherical roller bearing;
-
thrust needle bearing;
① Thrust cylindrical roller bearing
According to the different number of roller groups, the bearing is divided into single row cylindrical roller bearing and double row cylindrical roller bearing. Single row cylindrical roller bearing can bear single direction axial load and limit one direction axial displacement, double row cylindrical roller bearing can bear two-way axial load and limit two directions axial displacement.② Thrust tapered roller bearing
The inner and outer raceways are tapered, and the rolling body is also tapered roller. The extension lines of the three meet at the same point of the bearing axis line. The motion friction is smaller than other thrust roller bearings.③ Thrust spherical roller bearing
Because the load action line and axis form a certain angle, this kind of bearing can bear the axial and radial load at the same time, and can be used in the extremely heavy load situation, the allowable speed is also higher, the thrust self-aligning roller bearing has better self-aligning performance, but the allowable angular error decreases with the increase of the actual load applied to the bearing. -

Spherical Roller Bearing
Spherical roller bearing consists of a outer ring with a spherical raceway, a double raceway inner ring, one or two cages and a group of spherical rollers. Since the center of the spherical raceway of the outer ring is the same as the bearing center, it can automatically adjust the inclination or deflection of the shaft.¥ 0.00Details
-
Needle Roller Bearing
Needle roller bearing has small radial section size, good bearing rigidity, and high radial load bearing capacity, which is especially suitable for the occasion where the space of radial installation position is limited. It can also be widely used in the case of shaft and bearing pedestal swing.¥ 0.00Details
-
Tapered Roller Bearing
The tapered roller bearing is also as known as conical roller bearing. The inner ring of the bearing with roller and cage constitutes the inner assembly, which can be installed separately from the outer ring. The inner and outer rings of the bearing have tapered raceways, and the tapered roller is installed between the raceways.¥ 0.00Details

Cylindrical Roller Bearing
Cylindrical roller bearing is a separate type bearing, which is very convenient to install and disassemble. According to the number of rows of rolling elements installed in the bearing, it has different structures such as single row, double row and multi row cylindrical roller bearing.¥ 0.00Details
