(1) General theory of rolling bearings
1. Rolling bearing rollingbearing
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 singlerowbearing
Rolling bearing with a row of rolling elements.
3. Double row bearing doublerowbearing
Rolling bearing with two rows of tumblers.
4. Multi-row bearing multi-rowbearing
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 fullcomplementbearing
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 angularcontactbearing
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. Can't leave the bearing non-separablebearing
After the installation at the end; the bearing ring can not be freely detached 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 inchbearing
The original design dimensions and the rolling bearings indicated in English units.
11. Open bearing openbearing
Rolling bearing without dust cover and sealing ring.
12. Seal bearing sealedbearing
Rolling bearing with sealing ring on one or both sides.
13. Dust cover bearing shieldedbearing
Rolling bearing with dust cover on one or both sides.
14. Closed bearing cappedbearing
With one or two sealing rings; one or two dust caps and a sealing ring and a dust cover rolling bearing.
15. Smooth bearing prelubricatedbearing
The manufacturer is now filled with smoothing roller bearings.
16. Instrument fine bearing instrumentprecisionbearing
Instrument-specific rolling bearings.
17. Combination bearing matchedbearing
Paired into a pair or a set of rolling bearings.
