These large circular disc magnets generate a really impressive pull strength from 20kg (44.09lbs) - 50kg (110.23lbs). Within this range you will find our unique limpet' clamping magnets that combine the strength of a number of high-performance neodymium disc magnets into one assembly, generating an incredible pull strength. You will also find cylindrical magnets made from the strongest magnetic material available to buy. N52 neodymium magnets are so powerful they are commonly used in high-end engineering and manufacturing projects or for recovery and lifting applications.
