Flange-mounted 3:1 primary reduction on a compact footprint.
Flange-mounted planetary-type primary reduction units in PC71, PC80 and PC90 sizes. A fixed 3:1 step down at the motor, used to bring input speed into range ahead of a worm stage or to drive light machinery directly.

Built for Duty
What separates the PC Series from a general-purpose drive.
Fixed 3:1 primary step
One reduction ratio, sized to bring a standard motor speed into the band the next stage wants to see.
Flange mounted
Bolts directly to the motor face and to the driven machine, with no base frame and nothing to align.
IEC motor faces
PC71, PC80 and PC90 match the 71, 80 and 90 IEC frames of the motor range.
Short overall length
Adds very little to the motor stack, which is what makes it usable on crowded machine frames.
Stacks ahead of a worm stage
Used in front of an RW unit it multiplies the reduction without moving to a larger worm frame.
Sealed and grease filled
Filled for life, so there is no oil level to check on a unit mounted vertically or overhead.
