The steel pot concentrates magnetic holding performance at the working face. This B75 model is intended for applications where a large contact face and high axial pull rating are required. Confirm the mounting method, contact geometry, and surrounding clearance before installation.
The listed pull force is a laboratory reference under defined pull-off conditions, not a universal safe working load. Actual holding force varies with air gaps, paint, mating-steel thickness, surface finish, contact area, load direction, vibration, and temperature. Use the Magnet Pull Force Calculator for design estimates and compare materials in the Neodymium Magnet Grade Chart.
Use an appropriate engineering safety factor, particularly for vertical, overhead, dynamic, or personnel-adjacent applications. This magnet can create severe pinch hazards and can damage nearby equipment if allowed to snap onto steel.
