Material Description:

Our 25x20mm N52 cylinders are built for the most demanding technical environments. The significant volume of high-grade neodymium allows this magnet to act through large air gaps and thick non-ferrous barriers. Whether you are designing a magnetic coupling for heavy machinery or a industrial-grade separator for manufacturing, this cylinder provides a reliable, high-torque bond that is difficult to break.

Handling Advice: This magnet is extremely dangerous. With nearly 60 lbs of pull force, it can cause severe crush injuries or broken bones if fingers are caught between the magnet and a metal surface. Always use two hands and a non-magnetic spacer when handling. Keep at a significant distance from other large magnets.

Warnings and Safety Information:

• SEVERE CRUSH HAZARD: Can cause catastrophic hand injuries. Handle with extreme focus and heavy-duty gloves.
• Medical Safety: CRITICAL – Keep away from pacemakers and all electronic medical implants.
• Electronics: Will destroy hard drives, mechanical watches, and digital cameras instantly on contact.
• Storage: Store in a dedicated wood or heavy plastic box to prevent accidental "locking" to shelving or vehicle frames.

Applications:

• Industrial magnetic separators and filtration systems
• Heavy-duty actuators and high-torque magnetic couplings
• Securing heavy signage and industrial fixtures on steel structures
• Professional recovery of large metal objects in deep wells or tanks
• Experimental physics and high-flux magnetic field research
