Uses for ring magnets:

Strong ring magnets like these with a pull force of 12.6 kg are used to help hold and or regulate movement, release at a predetermined pull force, and or re-engage or hold again, moving parts. Sometimes threaded onto a spool or axle or rod, ring magnets, as well as regulating movement of nearby moving parts, also contain or compress moving parts that might otherwise drift from their allotted position and damage or reduce mechanical efficiency. The amount of magnetic force needs to be such that it can contain or compress the moving parts negating drift, 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.

  1. Magnetic power Review by Gary

    I needed magnets to hold a clamping caul inside a guitar top thru the top to clamp the bridge. Works well but they have a mind of their own and are stored separately in special box away from metal objects! (Posted on 1/8/2020)

  3. Good... Review by Matt cawood

    You guys were amazing as usual. The courier was rubbish. Their help line was hopeless. Local courier did the job of the customer service team. (Posted on 9/24/2018)
