EMR
The seal wiper element EMR is designed fort he demands of mini pneumatics. Compared with the profile ELR, smaller cross sections of the profiles are realized here. This involves marked lower friction values. Also this profile combines two functions in one: Sealing and wiping. No additional axial safeguard required.

ADVANTAGES ARE
- sealing and wiping in one element
- smallest place requirement but full function
- ideal housing finish
- low mounting effort
- simple and economical fitting area
- no additional axial safeguard required
- due to special lip geometry, even usable with dry and oil-free air after initial lubrication
- smooth running thanks to optimal tuning of the dynamicwiper and seal lips
- no corrosion danger because of the purely polymer part

APPLICATION RANGE
Especially designed for the sealing in the mini-pneumatics

 

working pressure:	≤ 1,6 MPa (16 bar)
working temperature:	- 35 �C to + 80 �C
surface speed:	≤ 1 m/s
media:	lubricated as well as dry and oil-free air (after initial lubrication)

MATERIAL
PU010 special polymerized polyurethane compound with a hardness of approx. 90 Shore A. For low temperature application the compound PU009 with a hardness of 94 Shore A is available.

 

MOUNTING INSTRUCTIONS
The seal / wiper element EMR is easy to be snapped into its fitting area when the piston rod is demounted. No further axial safeguard is necessary thanks to the outline of the profile. To avoid damage to the wiper and sealing lips, those should not be drawn over sharp edges during installation. An initial lubrication of the mating surfaces on assembly is important for very long service life.
