Deep groove ball bearings with stop grooves in the outer ring can be positioned with stop rings. During installation, the bearing can be easily fixed on the bearing seat. Therefore, when the axial installation position is limited, it should be preferred. According to the different characteristics of the bearing application, various combinations of dust covers, sealing rings, stop grooves, etc. can also be realized.

The deep groove ball bearing with a ball mouth is a special structure bearing with a ball mouth without a cage, a large number of steel balls, and a certain amount of locking in the inner and outer rings. There are two main designs: open or with guards on one or both sides. In addition, the bearings are available with or without retaining grooves. The outer ring of the open bearing has grooves and a dust cover can also be installed. Due to the large number of steel balls and high load-bearing capacity, deep groove ball bearings are widely used in large-load transmission components such as aviation and aerospace.

Ordinary deep groove ball bearings can meet most applications, but in some special places, such as extremely cold and hot environments, ordinary bearings cannot be used. As a result, high-temperature bearings were invented.

Thrust roller bearings are used to bear the combined axial and radial loads with the main axial load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed and self-aligning performance.

Single row bearings can bear radial load and unidirectional axial load, and double row bearings can bear radial load and bidirectional axial load.Suitable for bearing heavy load and shock load. According to the different contact Angle (α), it can be divided into three types: small cone Angle, middle cone Angle and large cone Angle. The larger the contact Angle is, the greater the axial load capacity is.

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings have tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single row tapered roller bearings can bear radial loads and single direction axial loads. When the bearing bears radial load, an axial component will be generated, so it needs another bearing that can bear the axial force in the opposite direction to balance it.
