PLYMOUTH, Mich., Oct. 17, 2013 /PRNewswire/ --For nearly 90 years, the
Freudenberg Simmerring^® Shaft Seal has been a synonym for reliable shaft
sealing. With its innovative designs, it has helped to shape technological
change like no other sealing element. Freudenberg-NOK Sealing Technologies'
application-oriented, advanced development of the Simmerring product line is
evident in its latest innovation– a Simmerring seal featuring electrically
conductive nonwoven material to help protect electric drive vehicle systems
from damage.

For decades, the Simmering seal has been the only sealing element that ideally
combines effective sealing, longevity and cost-effectiveness – and in many
applications, handling tasks beyond its sealing function. This new Simmerring
seal plays a crucial role when it comes to sealing shafts reliably and
economically while handling the additional job of safely draining off any
build-up of static electricity.

This Simmerring seal was especially developed for vehicles with electric
drives. It allows axle drives to be sealed extremely reliably, plus it drains
off the electrical charge that normally builds up on the drive shaft, safely
conducting it to the housing. In this way, the seal prevents the static charge
from traveling along the shaft into the transmission and damaging machine
elements as a result of dielectric breakdown.

Nonwovens make Simmerring seals conductive

Traditionally, transmission input shaft seals are enhanced with a conductive
nonwoven on the air side. The nonwoven creates a conductive bridge between the
shaft and the housing or grounding to safely drain off any static charges.

This means that manufacturers of drive components in electric vehicles now
have a proven method to seal shafts while conducting away electrical charges.
As a result, they no longer need additional measures to discharge the
electrical build-up.
