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
Style AN-M2 scrapers conform to MS28776-M2 sizes and are manufactured in brass. The scrapers are suitable for extreme environments with aggressive contaminants. The unique spring-loaded construction and ductile material result in close rod contact even when coping with rod ovality and helix grinding patterns.
