1. Rolling bearing
Bearings that roll between supporting loads and parts moving relative to each other, including parts with raceways and a rolling body group with or without isolating or guiding elements.It can be used to bear radial, axial or combined radial and axial loads.
2. Single-row bearing SingleRowBearing
A rolling bearing having a row of rolling bodies.
3. Double rowbearing doublerowbearing
A rolling bearing with two rows of rollers.
4. Multi-row bearing
For rolling bearings with more than two rows of rollers bearing loads in the same direction, it is best to indicate the number of columns and bearing types, for example, "four rows of centripetal cylindrical roller bearings".
5. Full roller bearing FullComplementBearing
For bearings without cages, the total clearance between the circumferential direction of each row of rolling body is less than the diameter of the rolling body and as small as possible to make the bearing have good performance.
6. Angle contactbearing AngularContactBearing
Rolling bearings whose nominal contact Angle is greater than 0° and less than 90°.
7 self-aligningbearing self-aligningbearing
A raceway is spherical, can adapt to the two raceway axis line between the angular deviation and angular movement of the bearing.
8. Separablebearing
Rolling bearings with detachable parts.
9. Non-separablebearing
After the final assembly, the bearing rings can not be freely separated from the rolling bearing.
Note: for bearings with different methods of separating parts, such as ball bearings with double half rings (02, 01, 08), no other abbreviated terms are specified.
10. Inchbearing
Rolling bearings whose dimensions and tolerances are expressed in English units when originally designed.
11 openbearing OpenBearing
Rolling bearings without dust cover and sealing ring.
12. Sealedbearing of seal ring
A rolling bearing with a sealing ring on one or both sides.
13. Dust cover bearing shieldedbearing
A rolling bearing with a dustproof cover on one or both sides.
14. Closed bearing CAPPEDBEARING
Rolling bearings with one or two sealing rings, one or two dust caps and one sealing ring and one dust cap.
15. PreLubricatedBearing
Rolling bearings that the manufacturer has filled with lubricant.
16. The instrument precision bearing instrumentprecisionbearing
Special rolling bearings for instruments.
17. Matchedbearing with a pair or a group of rolling bearings.
