HU Series

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.
