Additional information

This square key, part number 714-0118, fits into the shaft keyway to lock pulleys, gears, or sprockets in place so rotational force transfers reliably. Proper fit helps maintain alignment and consistent power delivery.

If a driven component slips on the shaft, chatters under load, or fails to move while the shaft turns, the key may be sheared, worn, or missing. Rounded edges or deformation can also prevent a secure fit.

Before starting the repair, disconnect the power source appropriate for your equipment to prevent accidental operation. Seat the key fully in the keyway, align the mating component carefully, and secure all fasteners so the assembly locks firmly in place.
