(1) Rolling bearing general theory 1. Rolling bearing
a bearing that tumbling between a load-bearing and mutually moving part; it contains race parts and a roll set with or without a barrier or guide. Can be used to accept radial, axial or radial and axial Combined load.
2. Single row bearing
Rolling bearing with a row of rolling elements.
3. Double row bearing
Rolling bearing with two rows of tumblers.
4. Multi-row bearing
Roller bearing with more than two rows; rolling bearings bearing the same direction of load; the best is to indicate the number of columns and bearing type; for example: "four-row radial cylindrical roller bearing".
5. Full complement rolling bearing
Bearings without cages; the total gap between the circumferential directions of each row of rolling elements is smaller than the diameter of the rolling body and as much as possible.
6. Angular touch bearing angular contact bearing
Rolling bearings with a nominal touch angle greater than 0° and less than 90°.
7. Self-aligning bearing
A raceway is spherical; a bearing that can get used to the angular error and angular motion between the two raceways.
8. Separable bearing
Rolling bearings with separate parts.
9. Not to leave the bearing non-separable bearing
After the end of the device; the bearing ring can not be arbitrarily separated from the rolling bearing.
Note: For bearings that do not leave the part differently; for example, ball bearings with double half rings (02, 01, 08) are not subject to regular abbreviations.
10. Inch bearing inch bearing
The original design dimensions and the rolling bearings indicated in English units.
11. Open bearing
Rolling bearing without dust cover and sealing ring.
12. Sealed bearing
Rolling bearing with sealing ring on one or both sides.
13. Dust cover bearing shielded bearing
Rolling bearing with dust cover on one or both sides.
14. Closed bearing
With one or two sealing rings; one or two dust caps and a sealing ring and a dust cover rolling bearing.
15. Pre-smooth bearing
The manufacturer is now filled with smoothing roller bearings.
16. Instrument fine bearing instrument
Instrument-specific rolling bearings.
17. Combination bearing
Paired into a pair or a set of rolling bearings.
. Noisy å²¢ 1. Radial bearing
It is primarily used for rolling bearings that accept radial loads; its nominal touch angle is between 0° and 45°; the fundamental parts are the inner ring, the outer ring and the roll with or without the cage.
2. Radial contact bearing
A centripetal rolling bearing with a nominal touch angle of 0°.
3. Angular contact radial bearing
A centripetal rolling bearing with a nominal touch angle greater than 0° to 45°.
4. Spherical bearing
Radial rolling bearing with outer spherical surface and wide inner ring with locking parts. It is mainly used for simple outer casing.
5. Tapered bore bearing
A centripetal rolling bearing with a tapered bore in the inner ring.
6. Flanged bearing
On one of its ferrules; usually a radial roller bearing with an outer radial flange on the outer ring or conical outer ring.
7. Roller bearing (rolling bearing)
a radial rolling bearing with a thick section outer ring; as a wheel tumbling on a rail; for example a cam track.
8. Retaining ring type roller (rolling) bearing yoke type track roller (rolling bearing)
Roller bearing with a pair of flat retaining rings.
9. Universal matching bearing
When you choose one or more sets of the same type of centripetal rolling bearings, you can get the characteristics of the paired or grouped devices.
.ㄈ┩å±Ï‡å²¢1. Thrust bearing
It is primarily used for rolling bearings that accept axial loads; its nominal touch angle is greater than 45° to 90; the basic parts are shaft rings, races and rollovers with or without cages.
2. Axial contact bearing
A thrust bearing with a nominal touch angle of 90°.
3. Angular touch thrust bearing angular contact thrust bearing
Thrust tumbling bearings with a nominal touch angle greater than 45° but less than 90°.
4. Single direction thrust bearing
A thrust tumbling bearing that can only accept axial loads in one direction.
5. Double direction thrust bearing
A thrust tumbling bearing that accepts axial loads in both directions.
6. Double row double-direction thrust bearing
Two-way thrust tumbling bearings with two rows of tumbling bodies; each column receives axial loads in only one direction.
7. Linear (motion) bearing linear(motion)bearing
Two rolling bearings have a relatively linear rolling bearing in the rolling direction.
.ㄋ模┣蛑岢1. Ball bearing
The roll body is the ball's roll bearing.
2. Radial ball bearing
1. The roll body is the radial roll bearing of the ball.
3. Deep groove ball bearing
Each ferrule has a centripetal ball bearing with a groove-shaped raceway having a cross-section of approximately one-third of the circumference of the ball.
4. Filling groove ball bearing filling slot ball bearing
Fill a groove on each rib of each groove of the grooved ball bearing; in order to be able to fill more balls.
5. Lock ball bearing counterbored ball bearing
A grooving ball bearing with a rib on the outer ring or some removed.
6. Three point touch ball bearing three point comtact ball bearing
Single-row angular touch ball bearings are subjected to pure radial load; each loaded ball has two touches with one channel; and one touch with the other. Under pure axial load; each ball and each A channel is just a touch.
7. Four point contact ball bearing
Single row angular touch ball bearings; when subjected to pure radial load; each loaded ball and two channels each have two touches; and when subjected to pure axial load; each touch is only a little touched.
8. Thrust ball bearing
1. The roll body is the thrust roller bearing of the ball.
9. Single row double direction thrust ball bearing single row double-directino thrust ball bearing
Four-point touch ball bearings with a touch angle greater than 45°.
10. Double row one-way thrust ball bearing doubel row single-direction thrust ball bearing
A one-way thrust ball bearing with a double volleyball concentric raceway and receiving the same direction load.
