Model HG electromagnetic chucks are less expensive than most of our other electromagnetic chucks with the exception of the Model HL economag chucks. The HG models has the most uniform holding of all of our electromagnetic chucks with a variance of approximately 10% holding power over the entire magnetic surface with an average of 75 pound plus hold down force per cubic inch.
Magna-Lock USA HR series electromagnetic chucks are an excellent choice for holding small and thin parts because of the fine lamination top plate design. They are less expensive than our HU series chucks, and their design can easily be modified prior to manufacture to accommodate our customer’s special applications.
Magna-Lock USA has been the supplier of rotary electromagnetic chucks for many of the world’s largest builders of rotary surface grinders since the in 1940’s. Most Mattison Machine Works rotary grinders were supplied with Magna-Lock USA chucks on the grinder and many are still in use today.
Economag low profile electromagnetic chucks offer the advantages of electrically operated chucks at a price competitive with less versatile permanent magnet chucks. Additionally, with the higher holding power available at the chuck extremities, magnetic holding power over the entire face of the chuck is more evenly distributed.
For years the HU series of electromagnetic chucks have been known as the Universal chucks in that it can be made in any special pole pattern and size. Many years ago, it was customary to change the poles from transverse to longitudinal at the customer’s request until the HL and HR series were fully developed. Today, we offer HU chucks with transverse poles only.
