ROTARY HUB SEALS

CASSETTE

Description

Complete unit consisting of a Simmerring and an integrated running surface. Economical system solution with integrated labyrinth to protect against extreme soiling. The integrated running surface meets the high demands placed on dynamic seals. * Lengthening of maintenance interval for individual units * Shaft must not be hardened or ground * Old solution can usually be replaced by Simmerring Cassette Seal without change to housing * The shaft must not be machined on maintenance or seal replacement

Application

Propeller shafts*, hubs and pinions on axles of commercialvvehicles (lorries, buses, trailers, special vehicles) Pinions on axles of construction machinery (road rollers,excavators, fork-lift trucks, mixers) and agricultural machinery (tractors)

Materials

Fluorinated Rubber (FKM)

ROTARY HUB SEALS

COMBI

Description

The Simmerring Combi Seal consists of at least two mounted elements which are preferably used in agricultural and construction machinery. In addition the PU element in this system can provide effective sealing for small axial motions. * Long service life * High resistance to dirt ingress due to the optimal positioning of sealing lip and dust lip

Application

Drives (agricultural vehicles, general industry) Agricultural machinery

Materials

Nitrile Rubber (NBR)

SHAFT SEALS FOR RECIPROCATING MOTION

DC4

Description

The DC4 profile is a shaft seal composed of a single metal cage with a rubber coating and a double sealing lip suitable for linear movements, the fluids being separated by the integrated springs. * Very good static sealing * Very good thermal expansion compensation * Greater roughness is allowed in the housing * Reduced risk of corrosion * Sealing for low and high viscosity fluids * Modern sealing lips with low radial forces * Sealing lips designed for linear movements * Fluid separation system

Application

All types of linear applications Shock absorbers Power-assisted steering
