Wipers | Spring energized wipers

 
Spring energized wipers
GENERALITIES Enerwiper  energized rod wipers are made up of a wiping element in Neuflon-ptfe, polyurethane or UHMW-PE, and an inox spring.
The special profile and the choice of materials make an extremely reliable component for completely preventing penetration of solid or liquid contaminants in the mechanical organs.
CHARACTERISTICS Long term maintenance of the pre-load.
Closed groove
Low friction
Protected wiping lip
Great chemical resistance
APPLICATIONS Hydraulics and pneumatics
Food and drugs (optional EU-FDA approved silicone filling)
Linear speed up to 5 m/sec and slow rotating movements
T range  -200  +260°C
