Ball Bearing Capstan Servo (BBCS) Rotary Tables
The A. G. Davis Ball Bearing Rotary Table consists of hardened steel faceplate supported by a maximum diameter preloaded A.G. Davis designed angular contact ball bearing. The large diameter ball bearing produces excellent wobble characteristics. The preloaded ball bearing along with the closed loop servo system provides for continuous as well as point to point measuring. A high grade meehanite base casting is used to support the ball bearing. Standard faceplate mounting pattern is by threaded hole patterns with other configurations available.
