Abstract: A nuclear magnetic resonance spinning apparatus includes an elongated cylindrical sample rotor with slotted air vanes on one tapered end thereof, an axial stator air drive and air end bearing, and a lateral ring air bearing around the opposite end of the rotor. The lateral end bearing retains the spinning axis at a precise pre-set angle, and the slotted air vanes are designed for high speed, low pressure applications. An adjustable cradle support mounts the spinning apparatus in a manner that allows convenient spin angle adjustment, and an insulated probe is provided with a convenient access opening and door structure for access to the spinning apparatus mounted therein.
