RSA
RSA
The RSA seal is designed with a shorter dynamic lip compared to the static one, suitable for applications with high rod misalignments and high pressure conditions. It can withstand pressures up to 400 bar at 60°C, speeds less than 0.5 m/s, and temperatures ranging from -35°C to +100°C, with peaks up to 110°C. It is compatible with mineral-based hydraulic fluids.
The seal is made from C0 type polyurethane, known for its high elasticity modulus, low compression-set, and high abrasion resistance. The hardness is specified as 93 Shore A ± 2.
To prevent damage, it is crucial to remove any flash and sharp edges in the housing and on the rod. Lubrication of the seal before assembly is recommended to facilitate the insertion of the rod. Detailed installation instructions are available on page 26.
The RSA seal complies with ISO/DIN 5597 and ISO 5597/1 standards.
A comprehensive list of RSA seal dimensions is provided, indicating various sizes and configurations available. For dimensions not listed in the catalogue, the technical department should be consulted.

RSA TENUTA STELO TIPO RSA Descrizione La guarnizione tipo RSA, progettata con labbro dinamico piu corto rispetto a quello statico, ha impieghi dove risultano elevati i disallineamenti dello stelo e dove le pressioni possono raggiungere valori elevati. Dati tecnici Pressione: < 400 bar a temperatura di 60° C Temperatura: da - 35° C a + 100° C con punte fino a 110° C Fluidi: fluidi idraulici a base minerale (vedi tabella 1 a pagina 12) Materiale Il materiale proposto e il poliuretano tipo C0 ad alto modulo elastico, basso compression-set ed elevata resistenza all'abrasione. Ha un durezza di 93 Shore A ± 2. Codice materiale: C0 Montaggio Per evitare che la guarnizione si danneggi occorre eliminare le bave e gli spigoli taglienti presenti nella sede e sullo stelo. E' sempre consigliato lubrificare la tenuta prima del montaggio per agevolare l'inserimento dello stelo. Per ulteriori informazioni leggere le istruzioni di montaggio a pag. 26. RSA TYPE ROD SEAL Description The RSA seal has a dynamic lip shorter than the static one and it is used in cases of high rod misalignments and possible high pressure. Technical data Pressure: < 400 bar, at a temperature of 60° C Temperature: from - 35° C to + 100° C, with peaks up to 110° C Fluids: mineral hydraulic fluids (see table 1, page 12) Material The proposed material is a “C0" type polyurethane, with high elasticity modulus, low compression-set and high abrasion resistance. The hardness is 93 Shore A ± 2. Compound reference: C0 Assembling To prevent any damage to the seal, remove any flash and cutting edges in the housing and on the rod. The seal should always be lubricated before assembling in order to have easier insertion of the rod. For further information please refer to the installation instructions on page 26.
