KDSA
KDSA
The KDSA compact seal consists of a central nitrile rubber (NBR) element that functions as a seal, two side supports acting as anti-extrusion rings, and two external guide rings that maintain the piston's alignment within the cylinder. The seal operates under pressures from 0 to 300 bar, with peaks up to 400 bar at 60°C. It supports speeds of less than 0.5 m/s and temperatures ranging from -30°C to +100°C. It is compatible with mineral oil-based fluids.
The central element is made of NBR with a hardness of 70 Shore A ± 3. The side supports are made of thermoplastic elastomer (TPE), and the external guides are made of polyacetal resin (POM). The standard material code is CX.
The seal can be assembled in either a closed groove on a monoblock piston or an open groove on a two-part piston. The assembly order is as follows: rubber element, supports, and wear rings. It is crucial that the piston is free of machining scores to prevent damage to the rubber element during installation.
The document lists various KDSA models with different dimensions, such as KDSA 0320 0240 155 CX and KDSA 1600 1430 265 CX. For dimensions not included in the catalogue, the technical department should be consulted.

KDSA TENUTA PISTONE COMPATTATIPO KDSA Descrizione La tenuta pistone compatta tipo KDSA 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. KDSA TYPE COMPACT PISTON SEAL Description The KDSA compact seal is made of a central unit made of 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 central units is made of NBR, the hardness is 70 Shore A ± 3 • The sides support are made of 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. The piston must not have machining scores which may damage the rubber unit during the installation.
