Pot magnets concentrate magnetic holding performance at the working face. Confirm the mounting method and contact surface before assembly, and account for air gaps, mating-steel thickness, surface finish, temperature, and load direction.
The listed 12.10 lb pull force is a reference value under specific test conditions, not a universal safe working load. Actual holding force varies by application, so use an appropriate safety factor for equipment and overhead installations.
Use the Magnet Pull Force Calculator for design estimates and compare material options in the Neodymium Magnet Grade Chart.
Browse stocked pot and mounting magnets, or use the Magnet RFQ Builder for volume pricing, custom mounting features, or a production requirement.
