Rod seal RSB 18x26x5,7 PU

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 18 mm, outer diameter 26 mm, sealing height 5,7 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.
