5. Bearing height
The axial spacing between the opposite sides of the two washers that limit the height of the thrust bearing.
6. Ferrule (washer) chamfering scale ring (washer) chamfer dimension
The ferrule (washer) has a chamfered appearance that extends somewhat in the radial or axial direction.
7. Radial chamfer dimension
The ferrule or washer is envisioned from the sharp corner to the gap between the end face of the ferrule or washer and the intersection of the chamfer.
8. Axial chamfer dimension
The ferrule or washer is conceived from the sharp corner to the inner hole of the ferrule or washer or the space between the outer and outer surfaces and the chamfered surface.
9. Flange width
The spacing between the ends of the flange.
10. Flange height
The radial dimension of the flange. The height of the outer flange is the radial spacing between the outer surface of the flange and the outer surface of the outer ring.
11. Stop ring groove diameter
The diameter of the cylindrical outer surface of the stop ring groove is 12. Stop ring groove width
The axial spacing between the ends of the ring groove.
13. Stop ring groove depth
The radial spacing between the cylindrical outer surface of the ring groove and the outer cylindrical outer surface.
14. Alignment surface radius
The radius of curvature of the spherical outer surface of the self-aligning seat, the self-aligning seat ring, the self-aligning outer ring or the outer outer ring.
15. Spherning surface centre height
The axial spacing between the curvature of the spherical reverse side of the spherical bearing of the thrust bearing and the opposite side of the opposite collar.
The model is planted in the test. Ball diameter
The spacing between two parallel planes that are tangent to the outer surface of the sphere.
2. Roller diameter
In the plane perpendicular to the axis of the roller axis (radial plane); the spacing between two tangent lines that are tangent to the outer surface of the roller. When calculating the extra load; use the radial plane in the middle of the roller.
3. Roller length
The spacing between the two radial planes including the end of the roller. However, the "roller length" used in accounting for additional loads is the theoretical maximum touch length of the roller and raceway at the shortest touch.
4. Pitch diameter of ball set
The diameter of a circle consisting of the center of a ball in a bearing.
5. Pitch diameter of roller set
The middle of a row of rollers in the bearing, the diameter of the circle running through the axis of the roller shaft.
6. Ball set bore diameter (outside diameter)
The diameter of the inner (external) cylinder of a row of balls in the bearing.
7. Roller set inner diameter (outer diameter) roller set bore diameter (outside diameter)
Radial touch roller bearing; diameter of an inscribed (external) cylinder of a row of rollers.
8. Ball integral bore diameter (outer diameter)
The diameter of the inscribed (external) cylinder of all the balls in the radial ball bearing.
9. Roller overall inner diameter (outer diameter) roller complemert bore diameter (outside diameter)
Radial touch roller bearing; the diameter of the inner (external) cylinder of all rollers.
