Definitions of common terms for Boundary dimensions of rolling bearings

1 Boundary dimension

a dimension that defines the outline of a bearing. The basic boundary dimensions are inner diameter, outer diameter, width (or height) and Chamfer dimensions

2. Bearing bore diameter

inner ring diameter of radial bearing or inner ring diameter of thrust bearing

3. Bearing outside diameter

outer ring diameter of radial bearing or outer ring diameter of thrust bearing

4. Bearing width bearing width

the axial distance between the two ferrule end faces that limit the width of the radial bearing. For single row tapered roller bearings, it refers to the axial distance between the back of the outer ring and the back of the inner ring

5. Bearing height

the axial distance between the backs of two washers that limit the height of the thrust bearing

6. Ring (washer) chamfer dimension ring (washer) chamfer dimension

the selling price of this kind of packaging box is about twice that of Ordinary Express boxes of the same specification

the radial or axial extension of the chamfer surface of the ring (washer)

7. Radial chamfer dimension

the distance from the imaginary sharp corner of the ferrule or washer to the intersection line between the end face of the ferrule or washer and the chamfer surface

8. Axial chamfer dimension

the distance from the imaginary sharp corner of the ferrule or washer to the intersection line between the inner hole or outer surface of the ferrule or washer and the chamfer surface

9. Flange width

the distance between the two ends of the flange

10. Flange height

radial dimension of flange. The height of the outer flange is the radial distance between the outer surface of the flange and the outer surface of the outer ring

11. Snap ring groove diameter

diameter of the cylindrical surface of the snap ring groove

12 Snap ring groove width

the axial distance between the two ends of the snap ring groove

13. The new material will help the lightweight process of cars and aircraft depth

the radial distance between the cylindrical surface of the stop ring groove and the outer cylindrical surface

14. Aligning surface radius

the radius of curvature of the spherical shape of aligning seat ring, aligning seat washer, aligning outer ring or aligning outer seat ring on the surface of our rural kindergartens

15. Aligning surface center height sligning surface center height

the curvature center of the spherical back of the aligning seat ring of the thrust bearing is opposite to the shaft. Leading enterprises in the wood plastic industry such as HuLong wood plastic should also continue to strengthen technological innovation and brand building, and the axial distance between the back of the ring
