Description
The WED bidirectional scraper has a combined scraper profile where the seal is provided with a scraping lip on the outside and a sealing lip on the inside.
The dimensions are interchangeable with normal scraper housings.
The scraping lip is very flexible and it compensate misalignments of the rod. The sealing side has a stronger and longer lip to ensure the sealing performance and to help the oil film remaining on the rod to go back into the cylinder.
The proposed material is a “C0” type polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance.
The hardness is 93 Shore A ± 2.
Compound reference: C0
It is also possible to use harder polyurethanes for heavy polluted environments.
In case please contact our technical department.
The assembling is extremely easy because of the semi-open groove.
Remove flashes an/or cutting edges in the housing.
For further information please refer to the installation instructions on page 26.
