1. Boundary dimension
Limited bearing the shape of a size, basic shape as the inside diameter, outside diameter, width (or height) and chamfer size.
2. Bearing bore diameter
To the radial bearing inner ring inner diameter or the thrust bearing shaft washer inner diameter.
3. Bearing outside diameter
To the radial bearing outer ring outside diameter or outside diameter of the thrust bearing seat.
4 bearing width of the bearing width
The axial distance between the two ferrule ends face limited width of the radial bearings, single row tapered roller bearings, the axial distance between the outer ring on the back of the inner ring on the back.
5. Bearing a high degree of bearing the height
Limit the axial distance between the two washers on the back of a high degree of thrust bearing.
6. Ring (washer) chamfer size ring (washer) chamfer dimension
Ring (washer) chamfer surface in the radial or axial extension.
7 radial, radial chamfer dimension chamfer dimension
The distance between the rings or washers hypothetical sharp corners to ring or gasket face and chamfer surface intersecting lines.
