Wipers

The style MW38 wiper is made from tough abrasion resistant polyester based material for difficult conditions found in mining and earth moving applications. It incorporates a sealing lip on the outside diameter to prevent moisture entering the groove.

Cadmium plated with gold chromate to QQL-614 and are inspected for required radial pressure, breakout friction, and rod light-tightness per spec. Manufactured to the MS28776 specification in accordance with the MIL-S-5049 procurement standard.

AM scrapers are typically used in heavy duty hydraulics like aircraft landing gear and steel mill cylinders.

Seal Options

• Solid scraping body only
• Scraping body with a narrow groove accommodating a serpentine form spring to scraping load
• Scraping body with a wide groove in the outside diameter accommodating two “c” style springs (resembling split washers) to generate scraping load

Two-piece, single acting wiper which consists of a PTFE ring and an o-ring energizer. This unique style provides low friction, free of stick-slip, and a high sliding speed.
