5. Separate collar (separable)
a separable ring with an "L" cross section; some of which are used as a rib for the inner ring of a radial cylindrical roller bearing.
6. Middle ring guide ring
a separable ring in a roller bearing with two or more rows of rollers; used to block two rows of rollers and guide the rollers.
7. Stop ring locating snap ring
a single port ring with a stable cross section; installed in the annular groove; axially positioning the tumble bearing in the casing or on the shaft.
8. Locking ring retaining snap ring
A single-mouth ring with a stable cross-section; installed in the annular groove as a retaining ring to hold the roller or the holder in the bearing.
9. Spacer spacer
Is a ring-shaped part; used between two bearing rings or bearing washers or between two half bearing rings or between two half bearing washers to maintain a regular axial spacing between them.
10. Seal seal
An annular cover consisting of one or several parts; fixed to a ferrule or washer of the bearing and touching or forming a narrow labyrinth gap with another ferrule or gasket; avoiding leakage of lubricating oil and invasion of foreign objects.
11. Dust cover shield
Is a ring cover; generally stamped from a thin metal plate; fixed to a ferrule or washer of the bearing; and extended toward the other ring or washer; covers the inner space of the bearing; but does not touch the other ring or washer .
12. Retainer flinger
A part attached to the inner ring or shaft ring; the use of centrifugal force to enhance the ability of the rolling bearing to avoid foreign objects.
13. Rolling element
A ball or roller that rolls between raceways. 14. Stick to cage
Some bearing part or some of the rolling body; and the bearing parts that move with it; to block the rolling body; and generally guide the rolling body and hold it in the bearing.
(2) Bearing component layout features 1. Raceway
The rolling bearing accepts some appearance of the load; it is used as a rolling track for the rolling body.
2. Straight raceway
The busbar in a plane perpendicular to the tumbling direction is a straight raceway.
3. Convex raceway
A substantially cylindrical or conical raceway with successive micro-curved curves in a plane perpendicular to the roll direction; to avoid stress gathering at the roller and raceway touch.
4. Spherical raceway
The raceway is a bit of a ball appearance.
5. Channel raceway groove
The ball bearing raceway is groove-shaped; generally a circular arc-shaped cross section; its radius is slightly larger than the radius of the ball.
6. Groove shoulder
The side of the ditch (rolling) road.
7. Rib rib
A narrow shoulder that protrudes parallel to the direction of the roll. It is used to support and guide the roll and hold it in the bearing.
8. Guide the appearance of the cage
The cylindrical outer surface of the bearing ring and washer; used to guide the bracket in the radial direction.
9. Ferrule (gasket) end face ring (washer) face
The outer surface of the ferrule (washer) perpendicular to the ferrule (washer) axis.
