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.

“Carcoflon” treatment gives a considerable reduction of dry friction coefficientbetween rubber & metal. UN: fitted with retaining plateUN/SF: fitted without retaining plate.

Carcoseal UN/LA/FS: All the advantages of LA combined with the V-ring frontal seal extra lip.

Carcoseal UN/LL: The lip is of a special geometry capable of sealing satisfactorily even large clearances and eccentricities.

Carcoseal SCA/ATLMP, Anti Twist Lip Protected Spring.

Carcoseal UN/LA: The lip add on the back offers protection from risk of damage by abrasive particles, scale and dust.
