Product catalog summary
Overview: The KDSB compact piston seal is designed for use in hydraulic systems. It consists of a central nitrile rubber (NBR) element for sealing, two thermoplastic elastomer (TPE) side supports acting as anti-extrusion rings, and two polyacetal resin (POM) external guide rings to maintain piston alignment within the cylinder.
Specifications:
  • Pressure: 0 to 300 bar, with peaks up to 400 bar at 60°C.
  • Speed: Less than 0.5 m/s.
  • Temperature Range: -30°C to +100°C.
  • Fluids: Compatible with mineral oils (refer to table 1 on page 12).
Materials:
  • Central Element: NBR with a hardness of 70 Shore A ± 3.
  • Side Supports: Thermoplastic elastomer (TPE).
  • External Guides: Polyacetal resin (POM).
  • Material Code: CX.
Assembly Instructions:
  • The seal can be assembled in either a closed groove on a mono-block piston or an open groove on a two-part piston.
  • Assembly order: Rubber element, supports, wear rings.
  • Avoid machining scores on the piston to prevent damage to the rubber element during installation.
Product Range: A comprehensive list of KDSB seal sizes is provided, ranging from KDSB 0200 0110 135 CX to KDSB 2500 2250 254 CX. For dimensions not included in the catalogue, contact the technical department.

KDSB TENUTA PISTONE COMPATTATIPO KDSB Descrizione La tenuta pistone compatta tipo KDSB e costituita da un elemento centrale in gomma nitrilica che esercita la funzione di tenuta, da due supporti laterali all'elemento in gomma che agiscono da anelli antiestrusione e da due guide esterne che mantengono in guida il pistone nel cilindro. Dati tecnici Pressione: da 0 a 300 bar con punte fino Temperatura: da - 30 °C a +100 °C Fluidi: oli a base minerale (vedi tabella 1 a pagina 12) Materiale I materiali utilizzati per la costruzione di questo tipo di tenuta sono i seguenti: • L'elemento centrale e in NBR con durezza 70 Shore A ± 3 • I supporti laterali sono in elastomero termoplastico (TPE) • Le guide esterne sono in resina poliacetalica (POM) Codice materiale standard: CX Montaggio Il montaggio di questa tenuta pud essere eseguito sia in cava chiusa su pistone monoblocco, sia in cava aperta su pistone in due pezzi. L'ordine del montaggio deve essere il seguente: • Elemento in gomma; • Supporti; • Guide. E' necessario che il pistone non presenti bave di lavorazione meccanica che danneggerebbero l'elemento in gomma durante il montaggio. KDSB TYPE COMPACT PISTON SEAL Description The KDSB compact seal is made of a central unit in NBR working as a seal, two side supports, working as anti-extrusion ring, and two external guide rings, keeping aligned the piston in the cylinder. Technical data Pressure: from 0 to 300 bar with peaks till Temperature: from - 30 °C at +100 °C Fluids: Mineral oils Material The compounds used to manufacture this seal type are the following: • The central units is made of NBR, the hardness is 70 Shore A ± 3 • The sides support are made of a thermoplastic elastomer (TPE) • The external wear rings are made of polyacetalic resin (POM) Compound reference: CX Assembling The assembling of this seal can be carried out in either closed groove in a mono-block piston, or in open groove in a two-parts piston. The assembling has to be done as follows: • Rubber element; • Supports; • Wear rings. Avoid machining scores on the piston which may damage the rubber unit during the installation.
