Oil Seals, Outer Diameter : 5mm, 10mm, 20mm

Oil seals for the shafts are of dynamic type in as much as sealing has to be provided between a rotating shaft and a stationery member. Int he vast majority of cases the internal pressure against which the seal has to work is very low and thus whist a simple lip seal may be adequate its performance depends to a large extent on a suitable unit load being maintained at the seal-shaft interface. The conventional form of Oil seal which is suitable for the majority of applications where the pressure involved is not more than about 5 PSI and the oil (or fluid) to be sealed is clean comprises a moulded elastomeric ring. For the majority of applications where a conventional single lip seal will be suitable, seal selection is based on seven basic points: namely shaft diameter, housing bore diameter and width, shaft speed, working temperature, fluid, pressure differential and service conditions.
