Holding force
All electro permanent magnetic circular chucks have a magnetically active diameter area. The holding force is
therefore only present within the area provided by the brass pole pitch. Please also note the catalogue documents,
web pages and the Appendix.

The stated holding force per workpiece area refers to a test workpiece with 100 x 100 x 40 mm made of steel
1.0037 with polished surface. If the application involves other conditions, the achievable holding forces may be
reduced substantially.
