Sealing ring - Import export

Elastomer NBR. Brace ring and tension spring steel. Rotary shaft lip seals are readytoinstall seals for sealing rotating shafts. They are made from an elastomer outer sleeve and an internal bracing shim. The tension spring ensures increased pressure of the lip against the shaft and supports static sealing. Form A DIN 3760 (ISO 6194/1) version, smooth OD. Form AS DIN 3760 (ISO 6194/0) version, smooth OD with extra dust lip to protect from external dirt. The material NBR has a high wear resistance and is resistant to motor fuels, oil, hydraulic oil and lubricating grease. Operating limits Circumferential speed (m/s) ≤12 Pressure (MPa/bar) ≤0.05/0.5 (rotary shaft lip seals are generally meant for unpressurised operation).

Orings are universal sealing elements used to seal against liquid or gaseous median. They are suitable for static and minor dynamic applications. Orings can be used for radial and axial sealing. The sealing occurs during installation by the radial or axial compression of the crosssection. During operation, the median pressure increases the deformation of the Oring and so increases the sealing effectiveness. For best sealing effectiveness, the Oring should have the largest possible crosssection. During installation the correct groove size, compaction, elongation/compression should be ensured. By static use the compaction should be 15 30% of the crosssection. By dynamic use it should be 10 18% (hydraulic), 4 12% (pneumatic). With regard to the ID, when installed the Oring should be stretched max 6% compressed max 3%
