DA22 Wiper

DA22

The scraper is a double-acting polyurethane wiper for closed groove installation. Significant improvements are achieved regarding the profile geometry and material used if compared with conventional elastomeric scrapers. The scraper lip is designed in a particular way that it reliably scrapes off the dirt but leaves a residual oil film on the rod, which is required for correct operation. The radial squeeze is sufficient to remove particles, dust and water.

The scraping lip facing inwards is designed in a way that it assumes a sealing function even under low pressure. The static seal is achieved by a tight radial fit between the scraper body and the groove.

Advantages:

• Good scraping effect

• Wear resistant, long service life

• Retaining residual oil film

• Standard elements for standardized installation grooves.

Operating Conditions:

• Working Temperature: -35°C to 100°C (-31°F to 212°F)
