An engineering drawing of the Fluidol Rota-Seal.


ROTA~SEAL is an all rubber, self-adjusting, shaft mounted radial lip seal. Its design keeps lubricants within bearing areas while excluding contaminants, ensuring safe and efficient operation.

The Fluidol Rota-Seal Seal Material Selection chart. DESIGN & CONSTRUCTION

ROTA~SEAL incorporates a tough but flexible hinged lip which seals axially against a radial (perpendicular) face. Compression molded of custom elastomers, ROTA~SEAL is highly resilient, fluid resistant and exhibits low wear characteristics.

The Fluidol Rota-Seal Dimensional Information chart. ROTA~SEAL requires no special machining for a tight fit around the shaft and cannot fret or groove expensive shafts like conventional spring loaded oil seals.


ROTA~SEAL can be stretched over shaft obstructions and pressed firmly against the radial face. After the shaft is set in operation, ROTA~SEAL self-adjusts after the first several rotations. Once adjusted, ROTA~SEAL will not "back-off" its position and automatically vents excess grease during regreasing operations.
