Description
The Vortex VXT825 XD is a shaft mount speed reducer with a 25:1 nominal ratio (exact ratio 24.33:1), 9.5-inch center distance, and AGMA size 315. The hollow output bore mounts directly over the driven conveyor or screw shaft using a separately ordered tapered bushing kit, with reaction torque transferred to a stationary frame through a separately ordered torque arm.

The Vortex VXT8 is built around a parallel-shaft helical gear arrangement housed in a cast iron case. Power enters through a solid input shaft on the high-speed side, typically driven by a V-belt sheave from a standard NEMA electric motor. The output is a hollow bore that fits over the driven conveyor or screw shaft using a separately ordered tapered bushing kit. Reaction torque from the reducer housing is taken by a separately ordered torque arm. The XD configuration uses heavy-duty seals and synthetic oil for service in indoor, outdoor, and washdown environments.
Typical applications: unit handling belt conveyors, bulk material handling conveyors, screw conveyors for grain and bulk powder, bucket elevators, industrial fans and blowers, mixer and agitator drives.
