23mm diameter, thick, cylindrical magnets. Made from neodymium for maximum strength these magnets are used for industrial applications.
Although unconventional, these deep cylindrical neodymium magnets are considered as ring magnets as they are supplied with a pre-drilled hole that goes all the way through the thickness of the magnet. These particular magnets provide an impressive pull of 16.5kg (36.38lbs) despite their compact size and are commonly used for engineering, manufacturing and technology where small size and maximum strength are required. What's more, because of their resistance to demagnetization they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
