RSO

Product catalog summary
Overview: The RSO seal type is designed to replace or work alongside PTFE stepseals, sharing the same groove dimensions. It features an internal rounded groove for housing an O-ring, which energizes the sealing lips even without pressure. This design is effective at low speeds and pressures due to its low friction and reduced axial dimensions, simplifying groove machining.
Specifications:
  • Pressure: Less than 250 bar at 60°C
  • Speed: Less than 0.5 m/s
  • Temperature Range: -35°C to +100°C, with peaks up to 110°C
  • Compatible Fluids: Mineral oils (refer to Table 1 on page 12)
Material: The seal is made from high elasticity modulus polyurethane type C0, with low compression-set and high abrasion resistance, energized by an NBR 70 O-ring. The hardness is 93 Shore A ± 2.
Installation Recommendations: Ensure removal of any flash or sharp edges in the seal housing. For detailed installation instructions, refer to page 26.
Compliance: The RSO seal complies with ISO/DIN 5597 and ISO 5597/1 standards.
Product Variants: A list of RSO seal variants is provided, indicating different dimensions and configurations, some of which are supplied without an O-ring or recommend open groove housing for easier installation.

RSO TENUTA STELO TIPO RSO Descrizione La tenuta tipo RSO e stata sviluppata per sostituire o per lavorare in tandem con guarnizioni a gradino in PTFE, avendo le stesse dimensioni di sede. Presenta al suo interno una gola arrotondata dove pud essere alloggiato ed inserito un o-ring che ha la funzione di energizzare i labbri di tenuta dinamico e statico anche in assenza di pressione. Questo profilo pud essere utilizzato anche a bassissima velocita e pressione con risultati eccellenti per il basso attrito sviluppato. Ha dei ridotti ingombri assiali e quindi lavorazioni di sede semplici. Dati tecnici Pressione: < 250 bar a temperatura di 60° C Temperatura: da - 35° C a + 100° C con punte fino a 110° C Fluidi: oli a base minerale (vedi tabella 1 a pagina 12) Materiale Il materiale proposto per la tenuta e il poliuretano tipo C0 ad alto modulo elastico (standard 93 Sh A), basso compression-set ed elevata resistenza all'abrasione energizzato da un o-ring in NBR 70 (N0). Codice materiale: CN (•) Montaggio Come per tutte le sedi dove alloggia la guarnizione occorre eliminare le bave e gli spigoli taglienti. Per ulteriori informazioni leggere le istruzioni di montaggio a pag. 26. RSO TYPE ROD SEAL Description The RSO seal type has been developed to replace or work jointly with stepseals in PTFE, because of the same groove dimension. Internally it has a round groove where an O-ring can be inserted and housed. The O-Ring acts as energizer for the static and dynamic sealing lips even without pressure. This profile has also excellent results at very low speed and pressure, because of the low friction. The machining of the groove is easier thanks to the reduced axial dimension. Technical data Pressure: < 250 bar at a temperature of 60° C Temperature: from - 35° C to + 100° C, with peaks till 110° C Fluids: mineral oils (see TABLE I, pages 12-13) (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, energized with O-ring in NBR 70 (N0). Compound reference: CN (•) Assembling As for all seal housings, remove any flash or cutting edges. For further information please refer to the installation instructions on page 26. in conformita alle norme ISO/DIN 5597 e ISO 5597/1 in accordance with ISO/DIN 5597 and ISO 5597/1 norms Sistemi di tenuta per oteodinamica Hydraulic sealing systems
