Deep groove ball bearings mainly bear radial loads, and can also bear radial loads and axial loads at the same time. If the deep groove ball bearing has a large radial clearance, it has angular contact performance. Product introduction:

Characteristics and uses of self-aligning ball bearings: The inner ring of the self-aligning ball bearing has two raceways, and the raceway of the outer ring is spherical, and the center of curvature of the spherical surface is consistent with the center of the bearing. Therefore, the inner ring, ball and cage can be tilted freely relative to the outer ring. Therefore, the deviation caused by the processing error of the outer shell can be automatically adjusted.

Characteristics and uses of angular contact ball bearings: Angular contact ball bearings have a higher maximum speed limit and can bear radial and axial loads at the same time, as well as pure axial loads. Their axial load capacity is determined by the contact angle and increases with the increase of the contact angle.

Characteristics and uses of cylindrical roller bearings: Cylindrical roller bearings are separable bearings, whose inner and outer rings are in linear contact with the rollers, with a small friction coefficient and a high maximum speed. The bearings are easy to install and disassemble, and can generally only bear radial loads. Only single-row cylindrical roller bearings with inner and outer ribs can bear smaller quantitative axial loads or larger clearance axial loads; bearings with single ribs can only bear axial loads in one direction; cylindrical roller bearings without inner or outer rings are used in parts with limited radial dimensions. The surface of the journal or housing hole is directly used as the rolling surface, and its surface hardness, processing accuracy and surface quality should be similar to the raceway of the ring. Cylindrical roller bearings can be divided into single-row, double-row and multi-row cylindrical roller bearings according to the number of rows of rolling elements installed in the bearing. Among them, single-row cylindrical roller bearings with cages are more commonly used. In addition, there are cylindrical roller bearings with other structures such as single-row or double-row full-fill rollers. Single-row cylindrical roller bearings are divided into N, NU, NJ, NF and NUP types according to the different ribs of the ferrule. Cylindrical roller bearings have a large radial load capacity and can also withstand certain unidirectional or bidirectional axial loads according to the structure of the ribs of the ferrule.

Characteristics and uses of tapered roller bearings: Tapered roller bearings are mainly suitable for bearing radial and axial combined loads dominated by radial loads, while large-cone-angle tapered roller bearings can be used to bear radial and axial combined loads dominated by axial loads. This type of bearing is a separable bearing, and its inner ring (including tapered rollers and retainers) and outer ring can be installed separately. The radial clearance and axial clearance of the bearing can be adjusted during installation and use, and it can also be installed with pre-interference.

Characteristics and uses of thrust ball bearings: Plane thrust ball bearings are divided into unidirectional and bidirectional types. Unidirectional plane thrust ball bearings are steel balls installed between a set of raceways. The contact angle is generally 90°. They can only withstand unidirectional axial loads and are not suitable for high-speed rotation. This type of bearing can be separated into three pieces, commonly known as three-piece bearings. Both gaskets have arc-shaped deep grooves for ball rolling.

Characteristics and uses of spherical roller bearings: Spherical roller bearings have two rows of rollers and are mainly used to bear radial loads, but can also bear axial loads in any direction. This type of bearing has a high radial load capacity and is particularly suitable for working under heavy loads or vibration loads, but cannot bear pure axial loads; it has good spherical performance and can compensate for coaxiality errors. Specific classification and model comparison:

Application and characteristics of needle roller bearings Needle roller bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Despite their small cross-section, the bearings have a high load-bearing capacity and are therefore particularly suitable for applications where radial space is limited.
