Description & Advantages

The NS-203 space-saving rotary seal type RODA is designed specifically for sealing rotating components. From profile width

3.9 mm it has a radial leakage/lubricant groove in the slide ring surface which provides a low friction, high sealing effect with

low break-away forces. The gap between rotor and stator must be smaller than that of the RDA due to the seal design. The

RODI  is to be preferred to the RODA due to its greater static contact surface.
