B+S RUO SEALING PARTS RS POLYPAC EU

Description

Today U-Cups are used primarily as seals for piston rods in hydraulic cylinders. U-Cups in polyurethane are proven elements, due to their good mechanical properties, for standard cylinder construction, particularly for mobile hydraulics under rough operating conditions.

The U-Cup is a single lip seal.

Type RUO

The U-Cup type RU0 is installed as a single-acting single-lip compact seal. The seal is installed with a simple snap fitting and seals statically on the outside diameter via a fixed seat. It has an asymmetric seal lip profile with shortened inner lip. This form can absorb deflections in the piston rod more easily than, e.g. U-Cup Form RU2 with its more rigid lip geometry. In pressure-free state, it exhibits lower frictional forces than double-lipped U-Cups.

Method of Operation

The sealing effect of the U-Cup comes from the intrinsic preload of the seal body and from the compression of the seal lips during installation. In operating condition, the radial mechanical contact forces are superimposed by the system pressure.

At low stroke speeds, U-Cups can tend to have a stick-slip effect due to an inadequate lubrication film formation in the seal clearance and to their material properties. This behaviour corresponds to the Stribeck curve described in the relevant literature.

Advantages

– Good pressure-adapted sealing effect
– Unaffected by high loads and deflections of the piston rod
– Good resistance to clearance extrusion
– Simple installation
– Lower friction in the low pressure range compared with double-lipped versions.

Technical Data

Operating pressure: Max. 40 MPa
Speed: Up to 0.5 m/s
Temperature: Use in mineral oils: -30°C to + 80°C
Media: Mineral oil-based hydraulic fluids.

Important Note:

The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value.

Seal clearance

Guide values for the radial clearance between rod and gland in relation to the operating pressure and rod diameter can be found in Table XXVII.

Material

The thermoplastic polyurethane material used for U-Cups has a high abrasion resistance, a low compression set and exhibits a high resistance to clearance extrusion.

Design and Installation Instructions

The different forms have different grooves, see Tables XXVIII and XXIX. U-Cups are used together with single-acting scrapers.
