Neyco offers a broad range of ferrofluid sealed rotary feedthroughs.

The technology of these feedthroughs is based on the ability of the ferrofluid, in the presence of a permanent magnetic field, to create a physical barrier to gases, vapours and other contaminants. The rings of ferrofluid thus form liquid seals.

Typically these feedthroughs consist of the ferrofluid, a permanent magnet, two stationary pole pieces, a housing and a shaft.

Advantages:

•     Long service life
•     High reliablility
•     Non-contaminating
•     High speed capability
•     Optimum torque transmission
•     Smooth operation due to low viscous drag

P/N generator:

Example : FRF (model) - S050 (shaft) - ISO100 (mounting) - M (actuator)

• Two models of rotary feedthroughs :

FRF = no water cooling

FRFC = water cooling

• Arbre:

SXXX = solid shaft + shaft diameter (mm)

HXXX = hollow shaft + shaft diameter (mm)

• Mounting:

ISO, CF, NM (nutmount)

• Actuator:

M = Manual

SM = Motorised

Fields of application:

•     Semiconductor processing
•     Robotics
•     Lamp manufacturing
•     Aerospace/defense industry
•     Fiber optic manufacturing
