1. Boundary dimension
A measure that limits the shape of a bearing; the fundamental dimensions are the inner diameter, outer diameter, width (or height), and chamfer dimensions.
2. Bearing inner diameter
The inner diameter of the inner ring of the radial bearing or the inner diameter of the axial ring of the thrust bearing.
3. Bearing outer diameter bearing outside diameter
The outer diameter of the outer ring of the radial bearing or the outer diameter of the thrust bearing.
4. Bearing width bearing width
The axial spacing between the end faces of the two ferrules that limit the width of the radial bearing; the single row tapered roller bearing refers to the axial spacing between the opposite side of the outer ring and the opposite side of the inner ring.
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
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.
