SDR Scraper

Sakagami SFR dust seals are low-friction seals designed for pneumatic cylinders used in indoor environments. They protect packings and cylinder internals from dust intrusion while supporting smooth operation. Best suited for clean, room-atmosphere conditions—SFR seals are not recommended for heavy-duty or outdoor applications.
