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

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.
