Product Description

Product Description
E4 20*12*5.5 NBR Pneumatic Piston Seal Pneumatic Cylinders Seals
The profile E4 piston seal is a lip seal specially developed for use in pneumatics. The dimensions of the profile E4 standard series correspond to the cylinder diameters according to ISO 3320, CETOP RP 52 P, RP 43 P and RP 53 P. Profile E4 is fully interchangeable with the profile C2 standard series formerly used in pneumatics.

Material Pressure Speed Temperature Hardness
NBR ≤16 bar ≤1 m/s -20ºC to +100ºC) ≈70 Shore A
FKM ≤16 bar ≤1 m/s -25ºC to +200ºC) ≈80 Shore A
TPU ≤16 bar ≤1 m/s -35ºC to +90ºC) ≈82 Shore A
1. Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
2. Suitable for cylinders with dead-center cushioning.
3. Good wear resistance.
4. Long service life thanks to applicationoptimized compounds.
5. Smooth running due to optimum lubricant-retaining sealing lip geometry.
6. Easier installation.
7. Suitable for fully automatic installation.
8. Assembly on one-part piston is possible.
9. High temperature resistance in case of suitable compound selection.
10. Excellent media resistance in case of  suitable compound selection.
11. Installation in closed housings.
12. Special seal geometry ensures optimal function even in case of flow-controlled exhaust air.

E4 20*12*5.5 NBR Pneumatic Piston Seal Pneumatic Cylinders SealsInstallation
The profile E4 lip seals are simply pulled over the piston into the groove. To avoid damaging the seal lips during installation, sharp edges should be removed from the piston and the cylinder tube.
Under oil-free conditions it is important to obtain a solid lubrication film inside the cylinder tube. This must be achieved before assembly to ensure a long service life of the seal.
For piston guidance we recommend the profile F2 piston guidance tape. Please refer to our profile F2 for details of the piston outside diameter and the gap measurements.
