What are the common terms for bearings?

(I) Radial bearings: 1. Radial bearings Radial bearing is mainly used for rolling bearings that bear radial loads. Its nominal contact angle is between 0° and 45°. The basic parts are inner ring, outer ring and with or without The cage's rolling elements.

2. Radial contact bearing radial contact bearing Nominal contact angle of 0 ° of the radial bearing.

3. angular contact radial bearing radial contact radial bearing nominal contact angle greater than 0 ° to 45 ° radial bearing.

4. Spherical bearing bearing Spherical roller bearing with outer spherical surface and wide inner ring with locking elements. Mainly used for simple shell.

5. Taper bearing tapered bore bearing inner ring tapered roller bearings.

6. Flanged bearing In one of its rings, it is generally a radial bearing with an outer radial flange on the outer ring or conical outer ring.

7. Roller (rolling) bearings track roller (rolling bearing) with a thick section of the outer ring of the radial bearing, as a wheel rolling on the guide, such as the cam guide.

8. Retainer type roller (rolling) bearing yoke type track roller (rolling bearing) is equipped with a pair of flat retaining ring roller bearing.

9.Universal matching bearing universal matching bearing When one or more sets of the same radial bearings are used together, they can be pre-determined for paired or grouped installations.

(b) General description of rolling bearings:

Rolling bearing A bearing that supports rolling motion between parts that move relative to each other and that includes race parts and rolling elements with or without isolation or guide elements. Can be used to withstand radial, axial or combined radial and axial loads.

2. Single row bearing single row bearing Rolling bearing with a row of rolling elements.

3. Double row bearing Double row bearing with two rows of rolling element bearings.

4. Multi-row bearings Multi-row bearing with more than two rows of rolling elements, bearing rolling bearings in the same direction, it is best to specify the number of columns and bearing types, such as: "four-row radial cylindrical roller bearings."

5. Full complement rolling element bearings full complement bearing without cage bearings, the sum of the gap between each row of rolling elements in the circumferential direction is less than the diameter of the rolling element and as small as possible, so that the bearing has a good performance.

6 angular contact bearings angular contact bearing nominal contact angle greater than 0 ° and less than 90 ° of the rolling bearing.

7. Self-aligning bearing A raceway is spherical, can adapt to the angular misalignment between the two raceway axis and angular motion bearings.

8. Separable bearing separable bearing Rolling bearing with detachable parts.

9. Inseparable bearing Non-separable bearing After the final assembly, the bearing ring can not be any freely separated rolling bearing.

Note: For bearings that separate parts in different ways, for example ball bearings with double and a half rings (02, 01, 08), no abbreviated term is specified.

10. Inch bearing inch bearing Original design dimensions and tolerances in English units of rolling bearings.

11. Open bearing open bearing Roller bearing without dust cover and seal ring.

12. Sealed ring bearing sealed bearing on one or both sides with a ring bearing.

13. Dust cap bearing shield bearing One or both sides of the roller bearing with a dust cover.

14. Closed-type bearings Capped bearings with one or two seals, one or two dust cover and a seal and a dust cover rolling bearings.

15. Pre-lubricated bearings Pre-lubricated bearing manufacturers have been filled with lubricant rolling bearings.

16. Instrument precision bearing instrument.

17. Matched bearings Matched pair or group of rolling bearings.

(3) Thrust bearing: 1. Thrust bearing thrust bearing is mainly used for rolling bearings bearing axial load, its nominal contact angle is greater than 45° to 90, and the basic parts are shaft ring, seat ring and rolling element with or without cage. .

2. Axial contact bearing axial contact bearing A nominal contact angle of 90 ° thrust bearings.

3. angular contact thrust bearings angular contact thrust bearing nominal contact angle greater than 45 ° but less than 90 ° thrust rolling bearings.

4. One-way thrust bearing single direction thrust bearing Thrust roller bearing that can only bear axial load in one direction.

5. Double-direction thrust bearing double-direction thrust bearing can withstand axial load thrust bearing in both directions.

6. Double row double direction thrust bearing Double row double-direction thrust bearing with two rows of rolling elements, each column is subject to axial load in only one direction.

7. Linear (motion) bearings linear (motion) bearing Two rolling bearings have relatively linear motion in the rolling direction.

(D) Ball bearings: 1. Ball bearings Ball bearings Rolling balls are ball bearings.

2. Radial ball bearing Radial ball bearing is a spherical ball bearing.

3. Deep groove ball bearings deep groove ball bearing each ring has a cross-section of approximately one-third of the ball circumference of the continuous groove ball bearings.

4. Filling slot ball bearing Filling slot ball bearing In each groove of the groove ball bearing, one rib is filled with a groove so that more balls can be filled.

5. Lock ball bearings counterbored ball bearing outer ring of a rib all or part of the groove ball bearings removed.

6. Three point contact ball bearings Three point comtact ball bearing Single row angular contact ball bearings When subjected to pure radial load, each loaded ball has two points of contact with one channel and one point of contact with another channel. With pure axial load, each ball has only one contact with each channel.

7. Four-point contact ball bearings Single point angular contact ball bearings, when subjected to pure radial load, each loaded ball and the two channels have two points of contact, and pure axial load when There is only one point of contact.

8. Thrust ball bearing thrust ball bearing Rolling ball is the thrust bearing of the ball.

9. Single row double direction ball bearing Single row double-directino thrust ball bearing Four point contact ball bearing with contact angle greater than 45°.

10. Double-row single-direction thrust ball bearings doubel row single-direction thrust ball bearings have double-volleyball concentric raceways and withstand the same.
