1. Rolling bearing: A bearing that rolls over between a load-bearing and mutually moving part; it contains race parts and a roll set with or without a barrier or guide; it can be used to accept radial, axial or radial Combined load with the axial direction,
2. Single row bearings: Rolling bearings with a row of rolling elements,
3. Double row bearing: Rolling bearing with two rows of rollovers,
4. Multi-row bearings: Roller bearings with more than two rows; roll bearings that accept loads in the same direction; best pointed out the number of columns and bearing type; for example: "four-row radial cylindrical roller bearings",
5. Full complement roll bearing: bearing without cage, the total gap between the circumferential direction of each row of rolling elements is smaller than the diameter of the roll body and as small as possible, so that the bearing has outstanding function.
6. Angular touch bearing: a rolling bearing with a nominal touch angle greater than 0° and less than 90°,
7. Self-aligning bearing: A raceway is a spherical shape, which can be used to the angular error and angular movement between the two raceways.
8. Bearings that can be separated: Rolling bearings with separate components,
9. Do not leave the bearing: After the installation at the end, the bearing ring can not be free to roll the bearing.
Note: For bearings that do not leave the part differently, for example, ball bearings with double ferrules (02, 01, 08) are not subject to regular abbreviations.
10. Inch bearings: the original design dimensions and the rolling bearings indicated in English units.
11. Open bearing: Rolling bearing without dust cover and sealing ring,
12. Seal bearing: a rolling bearing with a sealing ring on one or both sides.
13. Dust cover bearing:
Roller bearing with dust cover on one or both sides.
14. Closed bearing: Rolling bearing with one or two sealing rings, one or two dust caps and a sealing ring and a dust cap.
15. Sleeve bearing: The manufacturer has now filled the smoothing roller bearing.
16. Instrument fine bearing: instrument-specific rolling bearing,
17. Combination bearing: equipped with a pair or a set of rolling bearings.
