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 45 mm, outer diameter 55 mm, sealing height 11,5 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).
