20 Carcoseal Benefits Rubber compound with PTFE added to reduce friction Carcoflon PTFE surface treatment: Friction reduction; No stick slip effect; Lip protection during dry running. Stainless steel spring keeping lip homogeneously in contact with shaft. Large contact area: Guarantee against leakage; Less lip interference onto the shaft; Less heat generation; No shaft damage. Oil/Grease Retaining plate PTFE SHAFT SEAL LIP

21 MENISCUS EFFECT Lubricant is pumped into the contact zone by the shaft rotation and provides a separating oil film, reducing friction and providing cooling. The reverse pumping effect keeps the lubricant contained in the contact band.
