Cartridges & Mechanical Seals

114 AXIAL SPRING SEALS: CONICAL SECTORS: RNB / LS60B and RN.NB / LS60BDIN CHARACTERISTICS: • Balanced. • Single conical spring. • Dependent on the rotation direction. OPERATING LIMITS: d 1 = 10 ÷ 100 mm p= 50 kg/cm ² v= 20 m/s t= -20÷ +200oC ( *) ( * ) The temperature resistance depends on the material of the secondary seals used. The operating limits are defined by the PV factor which is determined for the sealing system characteristics and those of the application. DESCRIPTION: A versatile, robust single seal that is widely used in many different industrial and household applications. Suitable for working at high pressures. The rotating part, with a compact design, only per- mits the use of secondary seals made of elastic materials. Types: RN.NB/LS60BDIN: standardised models in accordan- ce with EN 12756 NB.
