Description
The Vortex XH237-5-140TC-1.25 is a hollow shaft worm gear speed reducer with a 5:1 nominal ratio (exact ratio 5.3:1) and 2.375-inch center distance. The NEMA 140TC input flange accepts a standard C-face motor, and the 1.25-inch hollow output bore (keyway: 3/8x3/16) slides directly over the driven shaft for conveyor head, mixer, and similar direct-mount applications.
