Pneumatic Seal E5
The profile E5 rod seal is a lip seal specially developed for use in pneumatics. The dimensions of the standard E5 profile series correspond to the rod diameters according to ISO 3320 and CETOP RP 51 P and are fully interchangeable with the C1 profile standard series formerly used in pneumatics.
• Due to application-optimized geometry and compounds suitable for use in oiled as well as in oil-free air (after initial lubrication on assembly).
• Robust seal profile for harshest operating conditions.
• Good wear resistance.
• Long service life thanks to applicationoptimized compounds.
• Smooth running due to optimum lubricant-retaining sealing lip geometry.
• Easier installation.
• High temperature resistance in case of suitable compound selection.
• Excellent media resistance in case of suitable compound selection.
• Installation in closed and undercut housings.
| Range of application | |
| Operating pressure | ≤ 16 bar |
| Operating temperature | -30 °C to +80 °C |
| Sliding speed | ≤ 1 m/s |
| Media | Compressed air, both lubricated and oil free (after greasing for fitting) |
Installation
The profile E5 lip seals can be easily snapped into the groove. In order to prevent damage to the seal lips during assembly, any sharp edges in the vicinity of the groove must be removed. The dynamic seal lip will only acquire its ultimate functional size if the dimensions of the installation groove are properly machined after installation. Under dry operating conditions it is absolutely essential to maintain a full lubrication film on the rod. This is ensured by appropriate initial lubrication. When using the profile E5 lip seal in pneumatic cylinders under non-lubricated conditions, a suitable wiper which does not destroy the lubrication film on the piston rod must be used. In this case, we recommend our profile A2 wiper specially designed for pneumatics.
