The Bomag 05851101 Woodruff Key is a genuine OEM component designed for a wide range of Bomag single drum rollers, tandem rollers, pneumatic tyred rollers, pavers, recyclers/stabilizers, refuse/landfill compactors, and soil compactors. Sourced directly from Bomag, this Woodruff Key meets the exact dimensional and material specifications required for proper shaft-to-hub engagement across the full range of compatible equipment. It fits an extensive lineup of Bomag machines, including BW 213 D-5 and BW 226 DH-5 single drum rollers, BF 800 C S500 and BF 900 C S600 pavers, BC 772 RB refuse/landfill compactors, BC 772 EB-2 soil compactors, and MPH 122 recyclers/stabilizers, among many others. Verifying part number 05851101 against your machine's serial number and model code before ordering ensures a correct, direct installation.
Key Features
- Genuine OEM Material Integrity — Manufactured to Bomag's exact hardness and dimensional tolerances for a Woodruff Key, ensuring the correct interference fit and shear strength at the shaft-hub interface.
- Drop-In Shaft Slot Fit — Machined to slot directly into the Woodruff keyway without filing or shimming, maintaining proper rotational alignment between shaft and mating component.
- Broad Equipment Coverage — Compatible with Bomag single drum rollers including the BW 213 D-5 and BW 226 PDH-5, tandem rollers including the BW 202 AD-4 and BW 164 AD, BF-series pavers, BC-series refuse/landfill compactors and soil compactors, pneumatic tyred rollers, and MPH-series recyclers/stabilizers.
- Torque Transmission Restored — A worn or missing Woodruff Key allows the hub to slip on the shaft, causing immediate loss of drive, drum, or accessory function; replacing this key restores full torque transfer and prevents accelerated shaft wear.
- Critical Drive-Train Safety — A correctly seated key prevents uncontrolled relative movement between rotating shaft and hub components, protecting operators and surrounding drivetrain parts from damage caused by key shear or slippage.
A Woodruff Key is a small, semi-circular metal key that seats into a curved keyway milled into a shaft, with the flat top face engaging a corresponding slot in the mating hub, pulley, or gear. Its job is to lock rotational motion between two components so that torque is transferred from the shaft to the driven part — or vice versa — without slipping. When a Woodruff Key shears, wears down, or falls out of its seat, the hub can spin freely on the shaft, causing immediate loss of function in whichever system that shaft drives, and often leading to expensive secondary damage to the shaft or hub if the machine continues to run. Replacing it promptly with a correctly sized, properly hardened OEM key is one of the most cost-effective drivetrain repairs available.
