Hishiko operates Magnet Applied Equipment division (formerly known as Fuji Jikoh Co. Ltd.)&Special Welding Consumables division.
The holding power of magnet varies substantially as per the conditions.
● Maximum Holding Power
Maximum holding power is found by contacting entire work face of the magnet on a fixed ideal load without air gap and pulling up vertically until the magnet tears loose.
| Ideal Load |
| Material ：ＳＳ400 or equivalent |
| Contact Surface ：∇∇∇ |
| Thickness ：Thick enough |
● Lifting Conditions
①Material of the Load
②Thickness of the Load
③Air Gap between the Magnet and the Load
④Contact Area of the Magnet
TThe holding power varies as per the material, thickness of the load, conditions of the contact surface and air gap between a magnet and the load.
① Effect of Thickness on Holding Power
※The holding power decreases as the plate become
As the size of magnet becomes smaller and/or pole pitch becomes smaller, comparatively the holding power to the thinner load increases.
② Effect of Air Gap on Holding Power
※The holding power decreases as the air gap between a magnet and a load become larger.
③ Effect of Material on Holding Powerbr /> ※ The holding power on SS400 is defined as standard.
④ Effect of Surface Roughness on Holding Power
