Dana Heavy Wear Rings HP803 – Piston

The Dana Heavy Wear ring is a universal guide ring for lubricated applications. Even when subjected to very high side loads, deformation of the material is extremely small. This is simply the best way to ensure that there is no metallic contact between piston and bore.


Application Examples

Working conditions:

Most Common Material DanaFlon
Guide ring  –30 to +100 °C
Basis Thermopolyester resin
Synthetic fabric
DanaFlon 803
Filler Aditive 
Colour Blue
Lubricating media yes
Extreme wear resistance  yes
Wide range of media (yes)
Non-lubricating media (yes)

The performance of the wear ring will always depend on the overall picture of the working conditions. Verification can only be done by testing the wear ring in the actual working conditions.
