Description
The RSD 56x66x6,5 PU U-ring is a product from the renowned Italian manufacturer Artic Seals. This double-lip ring, made of polyurethane C0, is ideal for use in hydraulic cylinders. Its design ensures excellent sealing, and the additional lip protects against external contamination. The RSD 56x66x6,5 PU U-ring prevents the stick-slip effect and works effectively even at low temperatures. Technical data: Seal size: 56x66x6,5 Manufacturer code: 2ERSD445 Material: Polyurethane C0 Working pressure: up to 400 bar Linear speed: up to 0,5 m/s Hardness: 93 Shore A ±2 The RSD 56x66x6,5 PU U-ring is a product with high abrasion resistance and low compression set. Ideal for use in hydraulic cylinders, it provides excellent sealing and protection against external contamination.
Material
PU / TPU / H-PU (polyurethane)
- Standard PU / TPU-30 °C to +80 °C
Best for high pressure and abrasion, in mineral hydraulic oil. Standard PU must never meet hot water, steam or brake fluid, or run hotter than +90 °C.
| Can be used | Do not use |
|---|---|
| Extreme pressure and pulsation (up to 40-50 MPa, very resistant to extrusion into the gap) | Hot water and steam with standard PU: hydrolysis, it breaks down into powder |
| Abrasion, friction, cutting and tearing (4-5 times tougher than NBR) | Glycol brake fluid (DOT 3, DOT 4, DOT 5.1): swells quickly |
| Mineral hydraulic oil (HL, HLP) and grease | High temperatures above +90 to +100 °C with standard TPU: it softens |
| Fuel oil, diesel and technical oils (aliphatic hydrocarbons) | Strong (concentrated) acids and alkalis: sulfuric, nitric, caustic soda |
| Ozone, weather and sunlight (does not crack from weather) | Acetone, MEK, toluene, benzene, dichloromethane (polar and aromatic solvents) |
| Water-based fire-resistant fluids HFA, HFB (only special H-PU) | Synthetic ester oils and fire-resistant fluid HFD-R |
| Dry compressed air and technical gases | Strong alcohols (methanol, ethanol): swelling |
Water and heat destroy standard PU: above +50 to +60 °C in water or damp oil it turns into a sticky paste or crumbles. If the system contains water or an emulsion, use only H-PU (hydrolysis-resistant).
