This very strong neodymium ring magnet measures 35 mm (OD) x 6.15 mm (ID) x 10 mm (T).
It has a pull force of 22.5 kg. GRADE N38.
Strong ring magnets like these, 35 mm x 10 mm with a pull force of 22.5 kg are used to help regulate the movement, release, and re-engagement of moving parts. The amount of magnetic force needs to be such that it can contain or compress the moving parts, but not so strong as to suppress movement necessary for efficient mechanical function. The known pull force or magnetic strength of a particular magnet allows engineers and others to design sophisticated equipment that is reliable and durable.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
