Wipers

Spring energized wipers

I raschiastelo Enerwiper consistono in un elemento raschiante in Neuflon ptfe, PU o UHMW-PE, energizzato da molla inox.
Il particolare profilo e la scelta dei materiali ne fanno un componente estremamente affidabile in grado di prevenire la penetrazione di contaminanti solidi e liquidi nella zona di guida e tenuta.
Abitualmente fornito con riempimento in silicone EU-FDA.

OVERVIEW
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
