A key is a small but critical drive component seated in a machined slot — the keyway — between a rotating shaft and a mating hub, pulley, or sprocket. It locks the two parts together rotationally, ensuring power is transferred cleanly without slippage. When a key wears, deforms, or shears, the driven component loses its positive connection to the shaft, which can result in loss of cutting function, vibration, or accelerated wear to the keyway itself. Replacing a damaged key promptly with the correct OEM component protects the surrounding shaft and hub from further damage.
