Description
The Vortex XH300-50-56C-1.4375 is a hollow shaft worm gear speed reducer with a 50:1 nominal ratio (exact ratio 50.0:1) and 3.0-inch center distance. The NEMA 56C input flange accepts a standard C-face motor, and the 1.4375-inch hollow output bore (keyway: 3/8x3/16) slides directly over the driven shaft for conveyor head, mixer, and similar direct-mount applications.
