No Matter you buy 1 pcs or 100,000 pcs of magnets, you can not find better service elsewhere.
Samarium Cobalt magnets, also known as rare earth magnets, offer the best value when comparing performance and size in high temperature or adverse environments.
Samarium Cobalt magnets are higher in cost, specially ring samarium cobalt ring magnet, but magnetically very strong and typically allow for dimensional reductions with higher precision.
GME can supply Samarium Cobalt Magnets with custom shapes and sizes, made-to-order Samarium Cobalt Magnets, or we can assist in developing a solution specifically for your application.
Specifications:
Dimensions: D70xD60x20mm smco magnets with chamfer
Tolerances: ±0.15 x ±0.15xmmx±0.15xmm
