Abstract
A spindle apparatus is composed of a holding member to define a casing, a spindle shaft to support a rotor rotatably, a neck bearing disposed radially of the spindle shaft, a buffer disposed between the holding member and the neck bearing, an end bearing secured to the end of the holding member remote from the rotor, and a mechanism provided between the buffer and the end bearing for transmitting power from a source of power to the spindle shaft for rotating the shaft. This spindle, rotatable at a high speed without any substantial vibration or noise, is applicable to spinning machines, more particularly to an overhung rotor.
