Price: -
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. Diameter 48mm
3. Vertical Pull-force: 90KG 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 90KG 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)
