ROTARY HUB SEALS

O SERIES

Description

High-performing, double acting compact piston seal composed of a profiled rubber ring, two polyurethane back-up rings and two POM back-up rings. Good sealing effect. Excellent extrusion & wear resistance. Reliable sealing for significant and sudden pressure variations. Assembly in closed groove, reduced machined costs. * High resistance to gap extrusion. * Particularly strong wear resistance. * Insensitivity to shock loads and pressure peaks.

Application

Agriculture Mobile machinery Hydraulic cylinders

Materials

Polyurethane (PU) + Nitrile Rubber (NBR)

OKC

Description

The OKC profile is an inverted shaft seal composed of a single metal cage with a rubber coating, a primary sealing lip without a spring and an additional anti-pollution sealing lip. * Very good static sealing * Very good thermal expansion compensation * Greater roughness is allowed in the fixed shaft * Reduced risk of corrosion * Sealing for high viscosity fluids * Primary sealing lip generating low levels of friction and heat * Protection against undesirable air contaminants

Application

All types of rotative applications Rotating hubs Fixed shafts

Materials

Rubber ACM 70 - 75 Shore A EPDM 70 - 75 Shore A FKM 70 - 75 Shore A HNBR 70 - 75 Shore A NBR 70 - 75 Shore A Metal cage Steel - AISI 1010
