TOLERANCES FOR FK3, FK5, AND FK6. VIEW TEXT
Modification of Groove Width and Diameter. If the Laminar Rings are subject to axial play during operation the groove width "A" or "B" has to be increased by twice the amount of end play encountered. In the case of radial runout the groove diameter "D1" has to be reduced by the amount of radial runout, while the diameter "D2" must be increased by the amount of radial play. Disregarding these recommendations will cause dammage. We recomment full use of the groove tolerance ( i.e. aim for the upper tolerance limit) especially if the seal arrangement is subject to thermal expansion. Increase groove width by 10% and use Gleitmo 980 for speeds from 1000 r.p.m upwards.
