These rubber-coated super magnets have a screw bush. The rubber coat can protect the working surfaces from scratches. The rubber coating is made from TPV which offers better durability.
Rubber-coated magnets with screw bush are another variant of the round rubberized magnets.
It is also combined with long durable TPV rubber, steel part and powerful neodymium magnets. The threaded bush could be mounted with different screws, hooks, and clamps which is totally according to the user’s applications.
The TPV is a trademark of thermoplastic vulcanizates which is a dynamically vulcanized alloy consisting mostly of fully cured EPDM rubber particles encapsulated in a polypropylene (PP) matrix. It combines the features of vulcanized rubber with the processing properties of thermoplastics. It has almost perfect performance and characteristics in the resistance to severe conditions.
The steel part is made of low carbon steel, but can also be stainless steel to meet the special requirement on corrosion resistance.
Different types of rubber-coated magnets are available
WZ Magnetics produces different kinds of rubber-coated magnets , with screw bush, threaded stud and screw hole. Each type can be used in different scenes whether you want. The complete series is from a diameter of 22mm to 88mm, and the maximum holding force for these rounds can reach 550N.
* We test the holding force of magnetic assembly by attaching it on a 20mm thick steel plate (low carbon steel with no coating) at room temperature and then pulling it slowly in vertical direction with the device that is sensitive enough to record the strength at the moment when magnetic assembly is separated from the steel plate. This is to give you a reference while the actual holding force in real application could be different with the change of pulling direction, thickness of the steel, surface treatment, etc.
