PRECISION (SPINDLE) MOTORS

Precision motors manufactured by Reuland offer the most flexibility both electrically and mechanically, while delivering exceptional performance. These motors are uniquely designed for extremely low vibration of 0.00005 inches peak-to-peak displacement and consist of a cast iron construction, bearing supports for added rigidity, and maximum shaft run out of 0.0005 inches T.I.R. Motor designs incorporate matched duplex, angular contact, and precision ABEC 7 bearings on both ends. Reuland Precision motors meet all NEMA mounting dimensions.


Precision motors are commonly used on machine tools, grinders, spindle drives, and test stands. Available in totally enclosed, open drip proof, and liquid cooled enclosures.
