Rolling bearings - Cylindrical roller bearings, separate thrust collars - Boundary dimensions
1 Scope
This Standard specifies the width, the maximum outside diameter, the bore and the bore minimum chamfer of separate thrust collars for cylindrical roller bearings in diameter series 0, 2, 3, and 4 as specified in ISO 15.
Dimensions for overall width and other geometrical features are not specified as they are dependent on the internal design of the bearings.
