Bearing structural features

Raceway raceway
The rolling bearing is subjected to the surface of the load part and serves as a rolling track for the rolling element.
Straight raceway straight raceway
The bus bar in the plane perpendicular to the rolling direction is a straight raceway.
Crowned raceway
A substantially cylindrical or conical raceway having a continuous microbending curve in a plane perpendicular to the rolling direction to prevent stress concentration at the contact of the roller with the raceway.
Spherical raceway
The raceway is part of the surface of the ball.
5. channel raceway groove
The ball bearing raceway is groove-shaped, usually a circular cross-section, the radius slightly larger than the ball radius.
6. (groove) shoulder (groove) shoulder
The side of the ditch (roll).
7. ribs ribs
Protruding from the raceway surface parallel to the rolling direction of the narrow shoulder. To support and guide the rolling body and keep it in the bearing.
8. Boot the cage on the surface
Bearing collar and washer cylindrical surface for guiding the cage in the radial direction.
The ring (washer)
A ring (washer) surface perpendicular to the center line of the ferrule (washer).
Bearing bore
The inner bore of a rolling bearing inner ring or shaft.
11. cylindrical bore cylindrical bore
Bearing or bearing parts of the bore, the bus is basically straight and parallel with the bearing axis or bearing parts axis line.
A tapered bore
Bearing or bearing parts of the hole, the bus is basically straight and with the bearing axis or bearing parts axis line intersect.
Bearing outside surface
Rolling the outer surface of the outer ring or seat.
The ring (washer) chamfered ring (washer) chamfer
The inner or outer surface of the ferrule (washer) that is connected to the end of the ferrule.
15. The process of passing through the track
The groove or groove of the bearing collar or bearing washer is for the groove or groove to facilitate grinding.
Sealing (contact) surface sealing (conract) surface
A surface in sliding contact with the seal ring.
Seal (shield) groove
The slot used to hold the bearing seal (dust cover).
18. snap ring groove
A groove for holding the retaining ring.
Lubrication groove
A groove for conveying the lubricant on the bearing part.
20. lubrication hole
On the bearing part, the lubricant is used to convey the lubricant to the hole in the rolling element.
