The error deviationfromcylindricalform of cylindricity
The measured contour of the minimum radial distance between the two coaxial cylinders, the cylindricity error.
Spherical error (substantially spherical surface) deviationfro msphericalform
The contour of the surface (inner surface) of the inner cutting sphere or around the external contour surface (outer surface) of the sphere and the contour surface at any point on any of the equatorial plane, the maximum radial distance.
Runout of assembled bearing inner ring (radial bearings) radialrunoutofassembledbearinginnerring
The inner ring in a different angular position, the surface of the inner bore relative to the outer ring a fixed point between the maximum and minimum radial distance of the difference. In the angular position of said point or in the vicinity of both sides at the rolling body should be provided with the inner and the outer ring raceway or the inner ring rear wall (tapered roller bearing) surface contacts the bearing parts, i.e. in the normal relative position .high speed bearings
Runout of assembled bearing outer ring (radial bearings) radialrunoutof assembledbearingouterring
The outer ring in a different angular position, a fixed point of the outer diameter surface and the opposite inner ring between maximum and minimum radial distance of the difference. Surface contact, i.e., the bearing part is in the normal relative position of the angular position of said point or should be in the vicinity of both sides of the rolling bodies with the inner and the outer ring raceway or the inner ring on the back wall (tapered roller bearing).
Radial clearance (can withstand pure radial load bearing, non to tight state) radialinternalclearance
When no external load is applied, in a different angular direction, and a ferrule with respect to another ferrule, the limit position toward the opposite limit position of radial distance from the arithmetic mean from a radially eccentric. This average includes a ferrule or the mutual displacement of the gasket in a different angular position and the rolling element set have diff erent angular positions relative to the ferrule or the amount of displacement of the gasket.
31 theoretical radial clearance (radial contact bearings) theoreticalradialinternalclearanceminiature bearing
The outer ring raceway contact diameter minus the inner raceway contact diameter minus twice the diameter of the rolling element.
32. Axial clearance (in both directions to withstand the axial load bearing, non-I tight state) axialinternalclearance
When no external load is applied, a ferrule or washers relative to the other ferrule or washer is moved from an axial limit position of the opposite limit position of the axial distance of the arithmetic mean. This average includes rings or washers in a different angular position of the mutual displacement, and a rolling element set at different angular positions with respect to the amount of displacement of rings or washers.
