Some common terms and definitions of rolling bearings, mainly rolling bearing generals, radial bearings, thrust bearings, ball bearings, roller bearings, etc.:
(1) General theory of rolling bearings:
1. Rolling bearing: A bearing that performs rolling motion between a load bearing and a moving part relative to each other, which includes a raceway part and a rolling body set with or without isolation or guides, which can be used to bear radial, axial or radial Combined load with the axial direction;
2. Single row bearing: a rolling bearing with a row of rolling elements;
3. Double row bearing: a rolling bearing with two rows of rolling elements;
4. Multi-row bearing: Rolling bearing with more than two rows, bearing rolling bearing in the same direction, it is best to indicate the number of columns and bearing type, for example: "four-row radial cylindrical roller bearing";
5. Full complement rolling element bearing: bearing without cage, the total gap between the circumferential direction of each row of rolling elements is smaller than the diameter of the rolling element and as small as possible, so that the bearing has good performance;
6. Angular contact bearing: a rolling bearing with a nominal contact angle greater than 0° and less than 90°;
7. Self-aligning bearing: a raceway is a spherical shape, which can adapt to the angular deviation and angular movement between the two raceway shaft lines;
8. Separable bearing: a rolling bearing with separable components;
9. Non-separable bearing: After the final assembly, the bearing ring can not be freely separated rolling bearing;
Note: For bearings with different parts to separate parts, for example, ball bearings with double half rings (02, 01, 08) do not specify abbreviated terminology;
10. Inch bearings: Rolling bearings in the original design when the dimensions and tolerances are expressed in English units;
11. Open bearing: rolling bearing without dust cover and sealing ring;
12. Sealing ring bearing: a rolling bearing with a sealing ring on one or both sides;
13. Dust cover bearing:
Rolling bearing with dust cover on one or both sides.
