Description

The RSB ring is a rod seal of a single-acting hydraulic cylinder, which on the dynamic side presents a multifunctional double lip. Product advantages: reduces stick-slip effects thanks because it keeps oil between the secondary lip and the main one stops any external impurities faces the material shrinkage at low temperatures acts as a stabilizer The selection of these sealing elements takes place by means of dimensions: inside diameter 40 mm, outer diameter 50 mm, sealing height 7 mm. It should be remembered that the width of the groove for these rings is slightly wider than the height of the gasket. The sealing material is Polyurethane C0 (93 Shore-A hardness), which is characterized by exceptional properties in terms of resistance to compression, abrasion and hydrolysis compared to conventional TPU based on polyester. Working temperature -35°C ... + 100°C, short-term up to + 110°C.

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).
