made up of N52 neodymium magnet and a steel shell, it can concentrate
the magnetic field on thebottomof magnet which increase the magnetic
force by 2.5-4 times compared to the naked magnet .
The steel cup can prevent the naked magnet from scratch and chipping during grabbing and clamping.
It
is designed for heavy duty and underwater useand helps to recover lost
equipment, tools, fishing tackles and other ferrous objects in deep
water, wells, holes. It is also great for magnet lifting, hanging
applications.
Specification
1. Material: Neodymium Magnet N52+A3 Steel+Black Resin
2. 180KG Size: Diameter 60mm
220KG Size: Diameter 75mm
300KG Size: Diameter 80mm
3. Vertical Pull-force: tested On Base of 30mm Thick Steel Plate via computer controlled tensile machine
4. Max Working Temperature:80 degree centigrade
Note:
1.The
magnetic force 180KG/220K/300KG is vertical pull-force which make the magnet pull
way from the thick 30mm steel plate of a tensile tester under ideal
condition. The actual pull force will vary mainly depending on the
following variables:
A: Steel thickness (The thicker the steel is, the stronger the pull force)
B:
Pulling direction (The smaller the angle taking 90° as a standard, the
stronger the pull force), the Pull force in horizontal direction is only
about one third of that in vertical direction)
C: Attracting position (The farther beyond the center of gravity of the attracted object, the lower the pull force)
