Rotary shaft seals | Rotowiper NRC

 
Rotowiper NRC
Rotowiper NRC for linear and/or slow rotating movements.
NRC ROTOWIPERS are made up of an element in NEUFLON-ptfe and an O-Ring which is the energyzing element.
Speed up to 120 rpm with a max. of 0.6 m/sec for the peripheral speed and 5m/sec for the linear movements
They are installed in the very same grooves of the NRC Wipers

APPLICATIONS

Hydraulics, pneumatics, chemical and food processing equipments
Temperature range -60 a + 250°C
