This Standard specifies nominal dimensions and tolerances of the rotary shaft lip-type seals with spring incorporating elastomeric sealing elements (hereafter referred to as “seals”) suitable for the range of shaft diameter from 6mm to 480 mm and the range of housing bore from 16 mm to 530 mm.
Seals shall be used under the low-pressure condition of 0kPa to 30kPa in gauge pressure, and classified into six types according to the construction. Respective basic types are as given in figure 1.
The seals without spring are shown in Annex JA.
