Product Family Hygienic Design Plastic Characteristics

Product description

Holding disks GN 7090 are used as counterparts for retaining magnets when these are used in connection with non-magnetic materials or when the holding force needs to be increased due to thin material.

They are intended for use in hygiene areas. The sealed screw-on surface enables mounting without dead spaces; the impervious geometry in combination with the high quality finish prevents dirt from accumulating and facilitates cleaning.

The holding disks can also be used in particularly aggressive environments thanks to the material used.

A normal holding force is achieved by combining retaining magnets with holding disks. Retaining magnets with north or south poles on the holding surface can be used equally.

If two retaining magnets with opposite polarity are combined, an increased holding force is achieved.

Combining two retaining magnets with the same polarity creates a repelling force.
