1. Rolling the theoretical rotating shaft of the imported bearing; the radial bearing is the inner ring axis; the thrust bearing is the shaft axis.
2. Inner ring (shaft) inner ring (shaft washer) axis of the inner cylinder (shaft ring) of the inner cylinder or the inner cylinder of the conical hole or the axis of the inscribed cone.
3. Outer ring (housing washer) axis If the outer ring of the outer ring is cylindrical; then the outer core of the external cylindrical axis is the outer ring axis; if it is the outer It is spherical; it passes through the outer surface of the outer ring of the outer ring; the line straight to the reference end face of the outer ring; the axis of the outer ring.
4. Conical inner ring (outer ring) axis line cone (cup) axis tapered roller bearing inner ring (outer ring) axis line.
5. A plane perpendicular to the axis of the axis; a plane parallel to the plane of the ferrule or the face of the back of the washer; can be considered a radial plane.
6. Radial radial direction in the radial plane through the direction of the axis.
7. A plane that accommodates the axis of the axis.
8. The axial direction is parallel to the direction of the bearing axis. It is straight with the ferrule reference end or the back of the washer; it can be considered axial.
9. Radial (axial) interval Radial (axial) distance measured in radial (axial).
10. The contact angle (nominal contact angle) between the plane (radial plane) perpendicular to the bearing axis line and the resultant effect line (nominal effect line) transmitted to the roll through the bearing ring or washer Angle.
11. Nominal contact point of the bearing point in the normal relative orientation; the point of the roll and the raceway touch.
12. The ferrule (gasket) reference end face reference face of a ring (a washer) bearing manufacturer specified as the reference surface of the ferrule (gasket) end face; can be used as a benchmark for measurement.
