Sealing - 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%

Material, version: 1. Sealing cap red Polyamide 66 thermoplastic. 2. Filler sieve black Polypropylene thermoplastic. 3 Flange electro zinc-plated steel. 4. Fastening screws electro zinc-plated steel. 5 Flange seal cork. 6. Chain brass.

Race body steel. Wipers plastic/felt. Longitudinal sealing lips rubber. Rollers steel 1.3505. Note Roller carriage with lifetimelubrication roller bearings and wipers which lubricate the system when moving. By simply moving the centre cam roller, the roller carriage can be adjusted so that it is free of play or has the desired pretension in the rail. High travel speeds up to 7 m/s and extremely quiet (faster and quieter than systems that use recirculating balls). The wipers are fitted with an oilsoaked felt. This felt is in constant contact with the track to ensure perfect lubrication. The felts can be recharged using an oil pump through the lubrication points on the front. On request Roller carriages with 4 or 5 rollers.
