1 Dimensions boundary dimension
Form of a limited size of the bearing, the basic dimensions as the inside diameter, outside diameter, width (or height) and chamfer size.
(2) bearing inner diameter bearing bore diameter
The inner diameter of the bearings or the shaft thrust bearing ring diameter.
3 bearing outside diameter
outside diameter of the thrust bearing seat.
4 bearing width of the bearing width
limit the width of the radial bearing two axial distances between the end rings, for single row tapered roller bearings with inner ring is the outer ring on the back of the axial distance between the back.
5 bearing height
limited height of the thrust bearing between the two washers on the back of the axial distance.
6 ring (washer) chamfer dimension
Rings (washers) Chamfer surface in the radial or axial extension.
7 radial chamfer dimension
Imaginary ring or gasket rings or washers to face sharp corners and chamfered surface distance between the intersecting lines.
8 axial chamfer dimension
Imaginary ring or gasket or washer sharp corners to the inner ring or outer surface of the hole chamfer surface and the distance between the intersecting lines.
9 flange width
the distance between the ends of the flange surface.
10 flange height
Radial flange dimensions. Outer flange of the outer surface of the flange and the height is outside the radial distance between the surface of outsiders.
11 snap ring groove diameter
Snap ring groove diameter of the cylindrical surface
12 snap ring groove width
Snap ring groove at both ends of the axial distance between the surfaces.
13 snap ring groove depth
Snap ring groove and the outer cylindrical surface of the radial distance between the cylindrical surfaces.
14 aligning surface radius
Aligning seat ring, aligning seat washers, spherical or spherical outer ring outside the seat of the spherical surface of radius of curvature.
15 slinging surface centre heights
thrust aligning bearing seat of the spherical center of curvature of the back of the shaft
