|/*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';|
A bearing ring with a double race; for example, the center of the double raceway inner ring (4) bearing washer 1. Shaft shaft washer
The bearing washer on the shaft.
2. Hobby hunting washer
The bearing washer in the seat.
3. Central circle
Bearing washers with raceways on both sides; between two rows of tumbling bodies for double row double direction thrust tumbling bearings.
4. Aligning housing
a seat with a spherical opposite; a eternal angular displacement between the axis of the axis and the axis of the seat axis.
5. Self-aligning seat washer
It is used for the gasket between the self-aligning seat and the outer casing of the thrust receiving body; its outer surface is a concave spherical surface and the spherical opposite surface of the self-aligning seat ring.
(5) Rolling body 1. Ball ball
Spherical roll body 2. Roller roller
a roll with a symmetrical axis and a circular cross section in either plane of the straight axis.
3. Ball (roller) overall ball (roller)complement
All balls (rollers) in a particular roll bearing.
4. Ball (roller) group ball (roller) set
Roll a ball (roller) inside the bearing.
5. Cylindrical roller
The busbar outside the roller is basically a straight line; and parallel to the roller axis.
6. Needle roller
Small diameter cylindrical rollers with a large ratio of length to diameter; usually between 3 and 10 times the diameter; but the diameter usually does not exceed 5 mm. The needle head can have several shapes.
7. Tapered roller tapered roller
The busbar outside the outer surface of the roller is basically a straight line; and intersects the roller axis line; usually a truncated cone.
8. (convex) ball convex roller convex roller
The outer surface of the roller is convexly curved in the plane including its axis.
9. Concave roller conveyor roller
The outer surface of the roller is concavely curved in a plane including its axis.
10. Symmetrical spherical roller convex symmetrical roller
The outer surface of the convex spherical roller is symmetrical at both ends of the plane passing through the middle of the roller and straight to its axis.
11. Asymmetric spherical roller
The outer surface of the convex spherical roller passes through the middle of the roller; the two ends of the plane perpendicular to the axis of the axis are symmetrically symmetric.
12. Convex roller
The outer surface of the substantially cylindrical or conical roller is in a plane including the axis of the roller; it is a continuous micro-convex curve; to avoid stress gathering at the end of the roller and the track touch.
