The size of components and parts
1ball diameter
Tangent to the surface with the ball the distance between two parallel planes.
2 roller diameter
Axis perpendicular to the line roller plane (radial plane), and tangent to the roller surface parallel to each other, the distance between two tangents. Calculation of the rated load, the application roller central radial plane.
3 roller lengths
Contains two roller end of the radial plane, including the distance between. However, when used in the calculation of the rated load of the "roller length" is a roller and raceway contact points in the shortest possible length of the theoretical maximum contact.
4 pitch diameter of ball set
Within a ball bearing center of the sphere diameter of a circle formed.
5 pitch diameter of roller set
within a roller bearing in the middle, the line runs through the roller axis diameter of a circle.
6 bore diameter (outside diameter)
Within a ball bearing internal (external) diameter of the cylinder.
7 roller set bore diameter (outside diameter)
Radial contact roller bearing, a roller of the internal (external) diameter of the cylinder.
8 ball complement bore diameter (outside diameter)
Radial ball bearings all ball internal (external) diameter of the cylinder.
9 roller complement bore diameter (outside diameter)
Radial contact roller bearings, all rollers of the internal (external) diameter of the cylinder.
