3. Convexity roller rolling in the direction perpendicular to the plane convex curve was continuous basic cylindrical or conical roller to prevent the roller and raceway contact of stress concentration.

4. Spherical ball raceway raceway portion of the surface.

5. Channel ball bearing raceway groove shape, usually an arc-shaped cross section, slightly larger than the radius of its radius.

6. (Groove) groove shoulder (roll) side of road.

7. Rib prominence in the raceway surface and rolling direction parallel to the narrow shroud. To support and guide the rolling elements and keep it in the bearing.

8. Guide the cage surface of the cylindrical bearing rings and gasket surface to the radial guide cage.

12. Conical bore bearing or bearing part of the inner hole, the bus was basically a straight line and with the bearing or bearing part axis line intersects the axis line.

13. Bearing outer surface of the bearing outer ring or the outer surface of seat.

14. Ring (gasket) chamfered bearing bore or the outer surface of one end connected with the ring ring (gasket) surface.

15. The more process slots in the bearing ring or bearing wall or flange gaskets to facilitate grinding the root of the open trench or slot.

17. Seals (dust cover) slot to maintain the bearing seal (dust cover) of the slot.

18. Snap ring groove to maintain the snap ring groove.

19. Lubrication groove in the bearing part on the slot used for the transmission lubricant.

20. Lubrication hole in the bearing parts, and used to transport the lubricant holes on rolling.

Double row angular contact ball slewing bearing (slewing ring)

Double-row slewing bearing has three seat, steel balls and isolation blocks can be directly discharged into the upper and lower raceway, according to stress conditions, arranged from top to bottom two rows of steel balls of different diameters.
