The width tolerance for a set of sealing washers is approximately ± 0,1 mm. If several sets of washers are mounted adjacent to each other, the nominal width will be reduced by 0,2 to 0,5 mm per set, depending on the force used to mount them. If the face of the cylindrical section of the washer abuts the chamfer of a bearing ring, there will also be a slight reduction in the width.
The remaining radial gap between the washers of a correctly mounted set will be at least 0,15 mm.
