Bearing industry common terms and definitions

Bearing: A) General 1 of rolling bearing. Rolling bearings rolling bearing load and the relative motion of the parts to each other in supporting intercropping of rolling bearing, it includes race parts and with or without isolation or guide roller group. Can be used to bear radial, axial or by a combination of radial and axial load. 2. Single bearing single row bearing has a list of rolling element bearing. 3. Double row bearing double rowbearing has two columns of the rolling bearing in the roller. 4. Multiple columns bearing multi - Row bearing has more than two columns of the scroll, load of rolling bearings under the same direction, it is best to point out that the number of columns and bearing types, for example: 'four column centripetal roller bearing. 5. Full rolling element bearing full complement bearing no bearing cage, each column of the gap between roller circumferential combined is less than the diameter of the rolling element and as small as possible, to make the bearing has good performance. 6. Angular contact bearings presents contact bearing nominal contact Angle is greater than 0 ° and less than 90 ° of rolling bearing. 7. Self-aligning bearing the self - Aligning bearing raceway is spherical shape, can adapt to the Angle between the two raceway axis deviation and Angle motion of the bearings. 8. Separable bearing is separable bearing is separable components of rolling bearing. 9. Non - integral bearing Separable bearing after final assembly, bearing ring are not free any separation of rolling bearing. Note: for different methods to separate parts of bearings, such as two and a half ring ( 02, 01, 08) Ball bearing is not the other provisions of the thumbnail. 10. Inch inch bearings bearing the original design dimension and tolerance to English unit said rolling bearing. 11. Bearing the open type bearing dust cover and sealing ring of the rolling bearing. 12. Seal bearing sealed bearing one side or two sides is equipped with sealing ring of the rolling bearing. 13. Dust cover bearing shielded bearing one side or two sides is equipped with dust cover of rolling bearing. 14. Closed type bearing capped with one or two seals, bearing one or two dust cover and a sealing ring and a rolling bearing dust cover. 15. To the lubricated bearing prelubricated bearing factory has been filling rolling bearing lubricants. 16. Instrument precision bearing instrument precision bearing apparatus dedicated rolling bearing. 17. Matched bearing matched bearing as a pair or a set of rolling bearing. ( 2) The centripetal bearing 1. The centripetal bearing radial bearing is mainly used to bear radial load of rolling bearings, the nominal contact Angle between 0 ° and 45 °, basic parts as the inner ring and outer ring and rolling body with or without a cage. 2. Radial bearing radial contact bearing nominal contact Angle for 0 ° centripetal roller bearing. 3. Angular contact centripetal bearing presents contact radial bearing nominal contact Angle is greater than 0 ° and 45 ° to the heart of rolling bearing. 4. Outside the spherical bearing insert bearing with spherical and with lock a wide centripetal roller bearing inner ring. Mainly for the use of simple shell. 5. Taper hole bearing tapered bore bearing inner ring with taper hole of centripetal roller bearing. 6. Flange bearing flanged bearing on its a ring, general is outer ring or cone to the flange on the outer diameter of the centripetal roller bearing. 7. Roller ( Rolling) Bearing track roller ( 滚动轴承) With thick section centripetal roller bearing outer ring, as a wheel rolls on the rail, such as CAM guide rail. 8. Retaining ring type roller ( Rolling) Bearing yoke type track roller ( 滚动轴承) Equipped with a pair of flat roller rolling bearing retainer. 9. Universal matched bearing universal matching bearing can choose any one or more of the same centripetal rolling bearings are used together, can get a grant to in pairs or in groups to install features by the rules
