Characteristics of bearing part structure

Raceway

The rolling bearing  bears the surface of the load portion and serves as a rolling track for the rolling elements.

2. Straight raceway straight raceway

The busbars in a plane perpendicular to the rolling direction are straight raceways.

3. Convex raceway crowned raceway

A substantially cylindrical {TodayHot} or conical raceway with a continuous micro-convex curve in a plane perpendicular to the rolling direction to prevent stress concentration at the roller-to-handle contact.

4. Spherical raceway

The raceway is part of the surface of the ball.

5. channel raceway groove

The ball bearing raceway is grooved, usually a circular arc-shaped cross section with a radius slightly larger than the radius of the ball.

6. (groove) shoulder

The side of the groove (rolling).

7. rib rib

A narrow shoulder that protrudes parallel to the rolling direction of the raceway surface. It is used to support and guide the rolling elements and keep them in the bearing.

8. Guide the surface of the cage

A cylindrical surface of the bearing ring and washer for guiding the cage in the radial direction.

9. Ferrule (gasket) end face ring (washer) face

A ferrule (washer) surface perpendicular to the ferrule (washer) axis.

10. Bearing bore bearing bore {HotTag}

The inner bore of the inner ring or shaft of the rolling bearing.

11. Cylindrical bore

The inner bore of a bearing or bearing part has a straight line that is substantially straight and parallel to the bearing shaft line or the bearing part axis.

12. Conical inner bore

The inner bore of a bearing or bearing part has a straight line that is substantially straight and intersects the bearing shaft line or the bearing part axis.

13. bearing outer surface bearing outside surface

Rolling bearing outer ring or outer surface of the race.

14. Ferrule (washer) chamfer ring (washer) chamfer

The surface of the ferrule (gasket) where the inner bore or outer surface of the bearing is connected to one end of the ferrule.

15. Overpassing groove grinding undercut

In the ferrule or flange of the bearing ring or bearing washer, the groove or groove is opened for easy grinding.

16. Sealing (contact) surface sealing (conract) surface

The surface that is in sliding contact with the seal.

17. Seal (dust cover) groove seal(shield)groove

A groove for holding a bearing seal (dust cover).

18. Stop ring groove snap ring groove

a slot to hold the stop ring.

19. Lubrication groove

A groove for conveying lubricant on a bearing part.

20. lubrication hole

On the bearing part, a hole for conveying the lubricant to the rolling elements.
