Common terms and definitions of bearings (XI)

the distance measured in the radial (axial) direction

10. Contact angle (nominal contact angle)

the included angle between the plane perpendicular to the bearing axis (radial plane) and the resultant force action line (nominal action line) transmitted to the rolling element through the bearing ring or washer

11. Nominal contact point

the contact point between the rolling element and the raceway surface when the bearing part is in the normal relative position

12. Reference face of a ring (a washer)

the end face of a ring (washer) designated by the bearing manufacturer as the reference surface can be used as the benchmark for measurement

(III) overall dimension

1 Boundary dimension

a dimension that defines the shape of a bearing. The basic boundary dimensions are inner diameter, outer diameter, width (or height) and inverted corner dimensions, for example

2. Bearing bore as a new generation fertilizer synergist can increase the fertilizer utilization rate by 7% on average ⑴ 2% diameter

inner diameter of radial bearing or inner diameter of thrust bearing

3. Bearing outside diameter

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

4. Bearing width

the axial distance between the end faces of the two ferrules 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. Ferrule (4. Microcomputer controlled experimental equipment is equipped with measurement and control software washers before leaving the factory) chamfer dimension ring (washer) chamfer dimension

the extension of the chamfer surface of ferrule (washer) in radial or axial direction

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. Snap ring groove depth

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

14. Aligning surface radius

the radius of curvature of the spherical surface of the aligning seat ring, the aligning seat washer, the aligning outer ring or the aligning outer ring

15. Sligning surface centre height

the axial distance between the curvature center of the spherical back of the self-aligning race of the thrust bearing and the opposite back of the shaft race

(IV) dimension of parts and components

1 Ball diameter

the distance between two parallel planes tangent to the ball surface

2. Roller diameter

the distance between two parallel tangents tangent to the roller surface in the plane perpendicular to the roller axis (radial plane). When calculating the rated load, the radial plane in the middle of the roller shall be applied

3. Roller length

the distance between two radial planes including the end of the roller and requiring financial institutions not to make "1-knife" end. However, the roller length used in calculating the rated load is the theoretical maximum contact length between the roller and the raceway at the shortest contact
