Description
The BWS wiper combines an asymmetric lip seal profile with a wiper.
On the sealing lip the BWS has a radius allowing greater smoothness and on the static side thereduced size step facilitates installation, especially for small diameters.
The scraping part has a very thin lip so as not to influence the stick-slip effect in the cylinder
movement.
Standard compound reference: B0
Alternative compound reference: A0
Remove cutting edges and/or flashes from the housing where the wiper has to be installed
in order to minimise seal wear during operation. Warning: for heavy duty applications showing misalignments or imbalance and with diameters bigger than ø 16 mm, it’s recommend to hang the base of the wiper to the housing and not only to the step
