(1) Rolling bearing general theory 1. A bearing in which a tumbling bearing is tumbling between a load-bearing and mutually moving part; it includes a raceway part and a tumbling set with or without a barrier or guide. It can be used to accept radial, axial or radial Axial combined load.
2. Single row bearings have a row of rollover bearings.
3. Double row bearings have two rows of rollover bearings.
4. Multi-row bearings have more than two rows of tumbling bodies; tumbling bearings that accept loads in the same direction; the best is to indicate the number of columns and the type of bearing; for example: "four-row radial cylindrical roller bearings".
5. Full complement roll bearing without cage bearing; the total gap between the circumferential direction of each row of rolling elements is smaller than the diameter of the roll body and as much as possible.
6. An angular contact bearing with a nominal touch angle greater than 0Â° and less than 90Â°.
7. The aligning bearing is a spherical shape; the bearing can be used to the angular error and angular movement between the two raceways.
8. The bearings that can be separated have tumbling bearings that can be separated from the parts.
9. Do not leave the bearing behind the end device; 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 half rings (02, 01, 08) are not subject to regular abbreviations.
10. The original dimensions of the inch bearing and the tumbling bearing indicated in English.
11. Open bearing without dust cover and sealing ring rolling bearing.
12. 1. A seal bearing with a sealing ring on one or both sides of the seal bearing.
13. A dust bearing with a dust cover on one or both sides.
14. Closed bearings with one or two seals; one or two dust caps and a seal bearing and a dust cover roll bearing.
15. The smooth bearing manufacturer is now filled with smoothing roller bearings.
16. Special rolling bearing for instrument bearing equipment.
17. The assembled bearing is matched into a pair or a set of rolling bearings.
(2) Radial bearing 1. Radial bearings are primarily used for rolling bearings that accept radial loads; their nominal touch angles are between 0Â° and 45Â°; the base parts are inner and outer rings and rollovers with or without cages.
2. Radial touch bearing has a nominal touch angle of 0Â°.
3. Angular touch radial bearing with a nominal touch angle greater than 0Â° to 45Â°.
4. The outer spherical bearing has a spherical outer surface and a wide inner ring of the inner ring with a locking member, which is mainly used for the simple outer casing.
5. 2. The tapered bore bearing has a tapered bore radial roller bearing.
6. The flange bearing is on one of its ferrules; usually a radial roller bearing with an outer radial flange on the outer ring or the outer ring of the cone.
7. Roller (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 ( )
Roller bearing with a pair of flat retaining rings.
9. The all-round assembly bearing is designed to be used together with one or more sets of the same radial rolling bearing; it is possible to obtain the characteristics of the pre-paired or grouped devices.
(3) Thrust bearing 1. Thrust bearings are primarily used for rolling bearings that accept axial loads; their nominal touch angles are greater than 45Â° to 90; the basic parts are shaft rings, races and roll cages with or without cages.
2. Axial touch bearing with a nominal touch angle of 90Â°.
3. Angular touch thrust bearing with a nominal touch angle greater than 45Â° but less than 90Â°.
4. A one-way thrust bearing can only accept axial load thrust rolling bearings in one direction.
