A-EIS-SL WIPER SEAL
The Ice Wiper A-EIS-SL is a combination of the versions A-EIS and A-EIS-S. The special feature is the
floating primary lip which can follow radial excursion
of the rod.
For challenging applications the A-EIS-SL is available in a stainless steel version.
The elastic secondary lip, made of PUR, NBR or FPM, prevents dust and moisture from entering.
