Rubber Covered Round Base Magnet Assemblies
RRB-S Series with a Stud

- Composed of Neodymium magnet, mild steel plate and the rubber coat which is to protect your parts from scratching.

- These cup magnets have a center hole, along with a nut, flat washer and spring washer.

- Max pull of the pot magnets is tested on a ½” thick and flat machined steel plate. The actual pull should be smaller if your steel is thinner, rough, rusty, coated or not very flat. For any critical applications, three-time safety factor is strongly recommended.

- Max operating temperature is 148°F (65°C)
