（1） Overview of Rolling Bearings

1. Rolling bearings

A bearing that performs rolling motion between parts supporting a load and moving relative to each other, comprising parts with raceways and rolling element groups with or without isolation or guidance. Can be used to withstand radial, axial, or combined radial and axial loads.

2. Single row bearing

A rolling bearing with a row of rolling elements.

3. Double row bearings

A rolling bearing with two columns of rolling elements.

4. Multi row bearings

For rolling bearings with more than two columns of rolling elements and bearing loads in the same direction, it is best to indicate the number of columns and the type of bearing, such as "four column radial cylindrical roller bearings".

5. Full complement bearing

For bearings without retainers, the total clearance between each row of rolling elements in the circumferential direction should be smaller than the diameter of the rolling elements and as small as possible to ensure good performance of the bearing.

6. Angular contact bearings

Rolling bearings with a nominal contact angle greater than 0 ° but less than 90 °.

7. Self aligning bearings

A bearing with a spherical raceway that can accommodate angular deviation and angular motion between the axis lines of two raceways.

8. Separable bearings

Rolling bearings with separable components.

9. Non separable bearings

After final assembly, the bearing rings cannot be freely separated in rolling bearings.

Note: For bearings with different methods of separating parts, such as ball bearings with double half rings (02, 01, 08), no abbreviated terms are specified.

10. British inch bearings

Rolling bearings with external dimensions and tolerances expressed in imperial units during the original design.

11. Open bearings

Rolling bearings without dust covers and sealing rings.

12. Sealed ring bearing

Rolling bearings with sealing rings installed on one or both sides.

13. Dust cover bearing shielded bearing

Rolling bearings with dust covers on one or both sides.

14. Closed type bearing capped bearing

A rolling bearing with one or two sealing rings, one or two dust covers, and one sealing ring and one dust cover.

15. Pre lubricated bearings

The rolling bearings that have been filled with lubricant by the manufacturing plant.

16. Instrument precision bearings

Specialized rolling bearings for instruments.

17. Matching bearings

A pair or group of rolling bearings.

（2） Radial bearing

1. Radial bearing

Mainly used for bearing radial loads in rolling bearings, with a nominal contact angle between 0 ° and 45 °, the basic components are the inner ring, outer ring, and rolling elements with or without a cage.

2. Radial contact bearing

3. Angular contact radial bearing

4. Outer spherical bearing insert bearing

A radial rolling bearing with an outer spherical surface and a wide inner ring with locking components. Mainly used for simple shells.

5. Tapped bore bearings with tapered holes

A radial rolling bearing with tapered holes in the inner ring.

6. Flanged bearings

On one of its rings, it is usually a radial rolling bearing with an outer diameter flange on the outer ring or conical outer ring.

7. Track roller (rolling bearing)

A radial rolling bearing with a thick cross-section outer ring, used as a wheel to roll on a guide rail, such as a cam guide rail.

8. Ring type track roller (rolling bearing)

A roller rolling bearing equipped with a pair of flat retaining rings.

9. Universal matching bearings

When selecting one or more identical sets of radial rolling bearings for use together, the predetermined characteristics for paired or grouped installation can be obtained.

（3） Thrust bearing

1. Thrust bearing

Mainly used for bearing axial loads in rolling bearings, with a nominal contact angle greater than 45 ° to 90 °, the basic components are shaft rings, seat rings, and rolling elements with or without retainers.

2. Axial contact bearing

A thrust bearing with a nominal contact angle of 90 °.

3. Angular contact thrust bearing

Thrust rolling bearings with a nominal contact angle greater than 45 ° but less than 90 °.

4. Single direction thrust bearing

A thrust rolling bearing that can only withstand axial loads in one direction.

5. Double direction thrust bearing

A thrust rolling bearing that can withstand axial loads in two directions.

6. Double row double direction thrust bearing

A bidirectional thrust rolling bearing with two columns of rolling elements, each column only bears axial load in one direction.

7. Linear (motion) bearings

A rolling bearing with two raceways that have relative linear motion in the rolling direction.

（4） Ball bearings

1. Ball bearings

Rolling elements are ball rolling bearings.

2. Radial ball bearing

The rolling element is a spherical centripetal rolling bearing.

3. Deep groove ball bearings

Each ring has a radial ball bearing with a continuous groove type raceway with a cross-section approximately one-third of the circumference of the ball.

4. Filling slot ball bearings

Install a filling groove on one edge of each ring of the groove type ball bearing to accommodate more balls.

5. Counterbore ball bearing

A groove type ball bearing with all or part of the outer rim removed.

6. Three point contact ball bearing

When a single row angular contact ball bearing is subjected to pure radial load, each loaded ball has two points of contact with one channel and one point of contact with the other channel. When subjected to pure axial load, each ball has only one point of contact with each channel.

7. Four point contact ball bearing
