Magnetic Product Description:
This rare earth ring magnet has an outside diameter of 30mm, an inside diameter of 15.5mm and a thickness of 8mm. It is identified by the AMF magnet part number 23003B.
Uses for our rare earth ring magnets:
Tension and compression systems within large scale constructions projects can embed ring magnets like these in order to increase the flexibility and durability of the buildings. Although massive, weighing millions of tonnes and reaching into the clouds, allowing these skyscrapers to move a little helps a lot. Allowing a building, especially a big one, gentle controlled movement when it wants to, helps control cracking, buckling and blowing, water ingress and constant repatching and repainting.
Ring magnets of many sizes and pull forces allow for slow release as different parts of a building expand with heat (the sun) or moisture (the rain). Alternatively, ring magnets in conjunction with tension and compression systems, help allow a building to shrink with the evening cool as different materials, like bricks and blocks contract at a different speed to other materials, mostly concrete.
Strong ring magnets like these, 30mmx8mm with a pull force of 13.5 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 positon and damage or otherwise reduce mechanical efficacy.
Magnets project their power without a restricting locking engagement, allowing mechanical parts to move at regulated intervals, releasing at a pre-determined pull force or within acceptable tolerances. Other engagement or fastening methods struggle for these highly desirable and nuanced capabilities.
These powerful ring magnets are in constant demand, most often in the mining, transport and grain processing sectors.
