First thrust angular contact ball bearing

Commonly used thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindles, generally used together with double row cylindrical roller bearings, can withstand two-way axial load, with high accuracy, good rigidity, low temperature rise, high speed, convenient installation and disassembly, etc.

Second deep groove ball bearing

Structurally, each ring of a deep groove ball bearing has a continuous groove raceway whose cross section is about one third of the equatorial circumference of the ball. Deep groove ball bearings are mainly used to bear radial load, but also can bear a certain axial load. When the radial clearance of spherical roller bearing increases, it has the property of angular contact ball bearing and can withstand the axial load alternating in two directions. Compared with other types of bearings of the same size, this type of bearings has small friction coefficient, high limit speed and high precision, so it is the preferred type of bearings for users when selecting. The deep groove ball bearing has the advantages of simple structure and convenient use. It is a kind of bearing with the largest production batch and the widest application range.

Third thrust tapered roller bearing

Because the rolling body in the thrust tapered roller bearing is a tapered roller, the rolling bus and the raceway bus of the washer converge at a certain point on the shaft line of the bearing on the structure, so the rolling surface can form pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing. Features: Thrust tapered roller bearing can withstand unidirectional axial load. The type code of thrust tapered roller bearing is Type 90000.

The fourth double row tapered roller bearing structure, performance characteristics

Double row tapered roller bearing structure is various, the largest number is 35000 type, there is a double raceway outer ring and two inner ring, there is a ring between the two inner ring, change the thickness of the ring can adjust the clearance. This kind of bearing can bear two-way axial load while bearing radial load, and can limit the axial displacement of shaft and housing within the axial clearance range of bearings. Structural characteristics of tapered roller bearings. The type code of tapered roller bearing is 30000, tapered roller bearing is separation type bearing. Tapered roller bearings are mainly used to bear radial and axial combined loads. Compared with the angular contact ball bearing, the bearing capacity is large, the limit speed is low. Tapered roller bearings can withstand axial load in one direction and can limit axial displacement of shaft or housing in one direction.
