The Bomag 09190807 Woodruff Key is a genuine OEM component designed for Bomag BW-series walk-behind light rollers and trench compactors, including the BW 75 AD, BW 75 ADL, BW 75 HS, BW 90 S, BW 85 T, BW 850 T, BW 850 TR, and BW 1050 T. As a direct OEM replacement sourced from Bomag, this Woodruff Key matches the original in material, dimensions, and fit — no guesswork required. Verified fitment against Bomag part number 09190807 ensures this key drops straight into place on compatible models.
Key Features
- OEM-Grade Hardened Steel — manufactured to Bomag's original material and dimensional spec, delivering the shear resistance and precise seating a Woodruff Key demands in rotating shaft applications
- Direct Drop-In Replacement — semi-circular profile seats fully into the shaft keyway, aligning the component to the shaft without secondary machining or fitting work
- Broad Model Coverage — fits BW 75 AD, BW 75 ADL, BW 75 HS, and BW 90 S walk-behind light rollers, plus BW 85 T, BW 850 T, BW 850 TR, and BW 1050 T trench compactors
- Torque Transmission Integrity — a correctly seated Woodruff Key locks the driven component squarely to the shaft, allowing full torque transfer; a sheared or missing key causes slippage and rapid wear to the shaft and hub
- Genuine Bomag OEM Part — supplied as an authentic Bomag replacement under part number 09190807, backed by OEM quality assurance
A Woodruff Key is a small but critical fastening component used to lock a rotating part — such as a pulley, flywheel, or drive hub — securely onto a shaft. It sits in a matching semi-circular slot milled into the shaft and a corresponding keyway in the mating component, preventing any rotational slipping between the two. When the Woodruff Key shears, wears, or goes missing, the driven component loses its positive connection to the shaft, resulting in loss of drive, component damage, and potential machine shutdown. Replacing this part promptly with a correctly sized OEM key restores full mechanical engagement and protects the shaft and hub from further damage.
