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)

MATERIALS
MATERIALS
FKM
Depending on their structure and fluorine content, the chemical resistance and resistance to the cold in fluororubbers can vary. This FKM-based rubber is very often used for high-temperature hydraulics and pneumatics, for industrial valves, injection/fuel systems, motor seals and high-vacuum systems.
