Designing machinery may not be the most artistic pursuit in the world, but sometimes the issue of color can be essential even in industrial design. A number of our metal parts can be produced in a variety of colors using a powder coating process.
JW Winco has its own in-house machining facility; this provides an advantage for our customers to take an idea and create a unique customized solution through the choice of using one of our standard parts.
Pulling Force Information for 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 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:
perpendicular "tear-off" under full surface contact of the magnet
workpieces made of low-carbon steel with a minimum thickness of 10 mm
1 Newton (N = .225 lbs.)
