E4型孔用氣動密封件-Parker - E4 (NBR) PNEUMATIC PISTON SEAL
E4 Profile Premium Rounded Lip U-cup Piston Seals
E4 Profile, Premium Rounded Lip U-cup Piston Seal
The profile E4 (NBR) 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.
Main advantages:
· Sealing lip geometry designed to operate with lubricated air as well as dry and oil-free air.
· Robust design based on favourable dimensions of seal cross-section.
· Tight fit into the groove ensures reliable operation.
· Optimal friction characteristics after careful initial lubrication obtained by sealing lip geometry retaining lubrication film.
· Suitable for cylinders with cushioning.
· Extended service life due to the use of proven elastomers.
· Easy snap assembly in grooves of simple design.
· Special seal geometry ensures optimal function with flow-controlled exhaust air.
