DanaStrip Wear Rings G
Piston & Rolls

DanaStrip is available with diamond pattern for constant high-quality lubrication. This is a universal guide band designed for moderate side loads. DanaStrip is chemically resistant to nearly all media. DanaFlon 29 is recommended for lubricated applications, and DanaFlon 32 for dry applications. Friction is extremely low and the diamond version reduces the friction further. This material is able to absorb foreign particles
