Ceramic Magnetic Bearing Turntable

The magnetic bearing consists of two opposing rings of small 6mm diameter neodymium magnets pres fitted into cnc machined acrylic discs.

Ceramic magnetic bearing turntable.

Bearing fits 37mm thick platter is 20mm in diameter and with a hollow spindle that extends 20mm from top of bearing.

The turntable itself is a home built and designed affair but the main bearing and platter are from a linn lp12.

The clearaudio cmb ceramic magnetic bearing is a result of long term research and development and is based on a clearaudio patent. Picture shows the bearing case before after plating. The upgrade features a ceramic alloy bearing material for the main shaft that is said to dramatically reduce friction along with a bearing housing that features magnetic donuts that repel one another. Designed to rotate loads of up to 25 000 lbs skf heavy duty turntables are available in cast iron in several sizes and designs.

Two aligned opposing magnetic fields are perfectly aligned one on top of the other thereby rejecting each other.
