Description

Rod seal RSD 140x155x11,5 PU is a product from the renowned Italian manufacturer Artic Seals. This is a double-lip ring made of polyurethane C0, intended for use in hydraulic cylinders. Seal size: Inner diameter: 140 mm Outer diameter: 155 mm Ring height: 11,5 mm Manufacturer code: 2ERSD764 Material: Polyurethane (PU) The RSD-type gland seal features both lips pressed against the mating surface thanks to the elasticity of the material. The additional lip stabilises the seal and protects it against external contamination. The design prevents the stick-slip effect and supports sealing performance at low temperatures. Technical data: Working pressure: up to 400 bar Linear speed: up to 0,5 m/s Hardness: 93 Shore A ±2 Material: polyurethane C0 with high abrasion resistance and low compression set Buying rod sealnia U RSD 140x155x11,5 PU is a guarantee of satisfaction and durability.

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.

Chemical resistance
Can be usedDo 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 greaseHigh 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 gasesStrong 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).
