Housing and threaded bushing
Stainless steel
Magnet
Hard ferrite SrFe (HF type)
GN 50.25 magnets are a shielded magnetic assembly.
Due to the lower magnetic conductivity of the stainless steel housing, the magnetic forces are lower than with steel.
Temperature resistant to 390°F (200°C).

GN 54.1 | Retaining Magnet Assemblies
*k is the maximum dimension by which the retaining magnet can be shortened without losing its properties.**Mounting these retaining magnets directly in steel components will create a magnetic short-circuit which reduces the magnetic power by as much as 15%. To avoid this effect, the k2 distance between the brass housing and the steel component should be observed. These distances should also be maintained if the retaining magnet is shortened.

*k is the maximum dimension by which the retaining magnet can be shortened without losing its properties.**Mounting these retaining magnets directly in steel components will create a magnetic short-circuit which reduces the magnetic power by as much as 15%. To avoid this effect, the k2 distance between the brass housing and the steel component should be observed. These distances should also be maintained if the retaining magnet is shortened.

26J. W. Winco Retaining Magnet Assemblies
The use of retaining magnet assemblies is a
simple solution for no-wear magnetic holding of
an object.
Due to their structure, these magnet assemblies
have only one magnetic pulling force level. The
full magnetic force is focused directly onto the
adhesive surface by means of iron magnetic
poles.
The spatial effect of the magnetic field is limited
by shielded systems, so that surrounding
objects are not magnetized.

Types of Retaining Magnet Assemblies
27J. W. Winco Retaining Magnet Assemblies
Hard ferrite (HF)
SrFe (Strontium ferrite).
Magnets made of hard ferrite (80% iron oxide)
are made by sintering process.
Like all ceramic materials, these magnets
are very hard and brittle and virtually non-
machinable.
The magnetic adhesive force drops when the
magnet is heated.
AlNiCo (AN)
Aluminium nickel cobalt.
Magnets made of AlNiCo (main constituents
include aluminium, nickel, cobalt and iron) are
made by sintering or casting process.
The material is very hard and tough, but can be
redressed.
These magnets are used in applications in
which the magnetic field is to remain as static
and stable as possible; also under higher
temperature fluctuations.
SmCo (SC)
Samarium cobalt.
Magnets made of SmCo (main constituents
include samarium and cobalt) are made by
sintering process.
The material is very hard and brittle and is
virtually non-machinable.
The magnetic adhesive force drops when the
magnet is heated.
NdFeB (ND)
Neodymium iron boron.
Magnets made of NdFeB (main constituents
include neodymium, iron and boron) are made
by sintering process.
The material is very hard and brittle and is
virtually non-machinable.
This material delivers ultimate magnetic holding
power.
The magnetic adhesive force drops when the
magnet is heated.

Comparison of Magnet Materials
Materials Composition of Retaining Magnet Assemblies
28J. W. Winco Retaining Magnet Assemblies
Other factors aside from the magnet material
and the size of the magnet affecting the
magnetic pulling force are:
- an air gap (magnetically non-conductive
materials act like an air gap)
- the quality of the surface (roughness and
shape)
- the temperature
- the content of ferro-magnetic material in the
steel; the components must also be sufficiently
thick to be able to absorb the entire magnetic
flux.
The magnetic pulling force can also be impaired
by alternating thermal stress and by chemical
factors (aggressive baths, gases, etc.).
The diagrams and graphs below show guide
values relating to the impact on the magnetic
pulling force caused by different mechanical
specifications.
The nominal magnetic pulling forces shown in
the tables of the standard pages are minimum
values which are achieved at:
- room temperature
- perpendicular “tear-off” under full surface
contact of the magnet
- workpieces made of low-carbon steel with
a minimum thickness of 10 mm

Hardened workpieces are bad conductors of the magnetic flux. The magnetic pulling force is therefore lower.
Influence of the air gap Influence of the material (steel grade)
Influence of the workpiece surface
on the magnetic pulling force
The displacement force is also influenced by the surface roughness and the magentic pulling force.
