Neodymium & Ceramic Magnetic Cup Assemblies

Round Base Magnets, also known as Round Cup Magnets, RB Magnets, cup or pot magnets are magnetic cup assemblies built with neodymium or ceramic ring magnets, encased in a steel cup with a countersunk or counterbored mounting hole. The magnetic holding force of these magnetic assemblies is multiplied many-fold with this type of design, and significantly stronger than individual magnets.

  • Neodymium Countersunk Magnets - have an incredibly powerful magnetic pull force, with a 90° countersink hole on the working surface to accommodate a standard flat-head screw to affix it to your product.

  • Ceramic Cup Magnets - are powerful magnetic assemblies composed of a ceramic ring magnet in a nickel- plated steel cup for maximum gripping power. Designed so the magnets have an inside diameter which is larger than the diameter of the hole in the cup, with a counterbored hole for screws so that the cup can be affixed to the item.

  • Applications - Both types are ideal for lifting, holding & positioning, and mounting applications requiring medium to very high magnetic strength. They are routinely used for indicators, lights, lamps, antennas, inspection equipment, furniture, cabinet making, gate latches, closing mechanisms, DIY projects, machinery, vehicles and more.

Approximate Pull Information:

The approximate pull info listed for round cup magnets are for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.
