Description
The Vortex XH206-15-56C-1.125 is a hollow shaft worm gear speed reducer with a 15:1 nominal ratio (exact ratio 15.5:1) and 2.062-inch center distance. The NEMA 56C input flange accepts a standard C-face motor, and the 1.125-inch hollow output bore (keyway: 1/4x1/8) slides directly over the driven shaft for conveyor head, mixer, and similar direct-mount applications.
