The single-lip springless oil seal is the simplest rotary-shaft sealing solution. With no spring, it seals entirely through the radial pressure created by the elastomer lip’s interference with the shaft.

Applications:Electric vehicles; motors; pivot bearings and actuator seals; vertical thrust bearings; power-system designs
