This Rare Earth ring magnet has an outside diameter of 20mm, an inside diameter of 4mm, and a height (or thickness) of 12.7mm. It has a pull force of 11.8 kilograms. It is identified by AMF Magnets part number 23014.
Wheels, castors and rollers often use ring magnets to assist in the smooth transit of people, goods and equipment. Huge tunnel boring machines and giant sight screens at stadiums run along horizontal tracks using super strength castors or rollers often with the assistance of magnets of different types.
Hospital beds, office chairs, factory equipment, drum, tub and piano dollies, all provide safe transit with the assistance of purpose built wheel, castor or roller assemblies. The type of wheel, castor or roller is determined by the size, weight and surface type the cargo will be traveling over.
Ring magnets, housed on the axle, rod or spool of some of these products help control movement of weighty items with their predictable and intuitive hold and release force field. The engagement of magnets, including ring magnets, allows for a more controlled, smoother start and stop to the wheel assemblies reducing the risk of collisions or other accidents and increasing the durability of the assemblies themselves.
These powerful ring magnets are also used widely in agriculture, construction, heavy engineering and shipping industries.

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
