Standard "C Flow" Configuration:

All dimensional and driven data presented on this page assumes a standard "C Flow" configuration, where the motor shaft and driven shaft are on the same side.

Additionally, we are assuming that the controllable (mechanical) pulley is mounted on the motor shaft, and the spring-loaded pulley is mounted on the driven shaft.

"Z Flow" Configuration:

"Z Flow" configurations, where the motor shaft and driven shaft are on opposite sides, are also common.

While the driven data does not change i.e. output speeds, horsepower ratings, etc., the spring loaded driven pulley must be ordered as a reverse bore.

Dimensional data does change, but we can provide a layout drawing of the configuration upon request.

"Thru-Bore" Configuration:

Some applications require that the driven shaft pass all the way through the spring-loaded driven pulley.

Dimensional and driven data relative to our standard configuration do not change, but the spring-loaded driven pulley must be ordered as a through bore.

"Reverse" Installation:

Not to be confused with a reverse bore, this configuration calls for the spring-loaded pulley to be mounted on the motor, and the controllable (mechanical) pulley to be mounted on the driven shaft.

Dimensional and driven data change significantly relative to our standard configuration, but we can provide dimensional and driven data for such an installation upon request.
