(5) Rolling body 1. Ball ball Spherical rolling element 2. Roller roller A rolling element having a symmetrical axis and a circular cross section in any plane perpendicular to its axis. 3. Ball (roller) overall ball (roller)complement All balls (rollers) in a particular rolling bearing. 4. Ball (roller) set ball (roller) set A row of balls (rollers) in the rolling bearing. 5. Cylindrical roller The outer busbar of the roller is basically straight and parallel to the roller axis. 6. Needle needle A small diameter cylindrical roller with a large ratio of length to diameter. The length is generally between 3 and 10 times the diameter, but the diameter is usually not more than 5 mm. The needle head can have several shapes. 7. Tapered roller The outer busbar of the roller is basically straight and intersects the roller axis, usually a truncated cone. 8. (convex) ball convex roller convex roller The outer surface of the roller is convexly curved on the plane containing its axis. 9. Concave roller The outer surface of the roller is concavely curved in a plane containing its axis. 10. Symmetrical spherical roller convex symmetrical roller The outer surface of a convex spherical roller is symmetrical on both sides of a plane passing through the middle of the roller and perpendicular to its axis. 11. Asymmetrical roller The outer surface of the convex spherical roller is asymmetrical on both sides of the plane passing through the middle of the roller and perpendicular to its axis. 12. crowned roller is a cylindrical or conical roller whose outer surface is in a plane containing the axis of the roller and has a continuous micro-convex curve to prevent the end of the roller from contacting the raceway. Stress concentration occurs. 13. Relief roller The reliefd end roller has a slightly modified diameter at the end of the outer surface of the roller to prevent stress concentration at the end where the roller contacts the raceway. 14. Spiral roller A spiral wound roller is wound into a spiral roller. 15. Roller end face The roller end face is substantially perpendicular to the end surface of the roller axis. 16. Roller end face roller lavge end face The end face of a tapered roller or an asymmetrical spherical roller. 17. Roller small end face The end face of a tapered roller or an asymmetrical spherical roller head. 18. Roller chamfer roller chamfer The surface of the outer surface of the roller that is connected to the end face. (vi) Cage 1. Wave cage A cage consisting of one or two wavy annular parts. 2. Cage pocket A cage hole or opening in the cage to accommodate one or more rolling elements. 3. cage beam A part of the cage that separates the adjacent cage pockets. 4. Cage claw cage prong A cantilever that extends from the cage or half cage. 5. Cage The cage pin is generally a cylindrical post that can be used through the axial bore of the roller. 6. Guard-guided cage The terrain riding cage is a radially guided (centered) cage from the shoulder of the bearing ring or bearing washer.
