Carcoseal BenefitsRubber 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.

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.
