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.
