The space-saving rotary seal type RODI 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 RDI due to the seal design.
The RODI is preferred to the RODA due to its greater
static contact surface.
Depending on the specifications and operating conditions
it is recommended to have the running surface
hardened to approx. 56 HRC or hard chromium plated.
