The Bomag 09181208 Fitting Key is a genuine OEM component designed for Bomag BW-series walk-behind and light rollers and BW 35 trench compactors. Sourced directly from Bomag, this fitting key delivers the exact dimensional tolerances required for a correct, secure installation with no guesswork. It is confirmed compatible with the BW 60 S, BW 65 HS, BW 65 S, BW 65 S-2, BW 75 S-2, BW 75 E, BW 75 S, BW 90 S walk-behind and light rollers, and the BW 35 and BW 35 W trench compactors. When it comes to small precision drive components like this, using the genuine Bomag part ensures the mating shaft and hub assembly seats and transmits torque exactly as the machine was engineered to do.
Key Features
- OEM Dimensional Accuracy — machined to Bomag's exact profile, ensuring the key seats flush in the keyway without play or stress concentration that can damage the shaft or hub
- Drop-In Installation — matches the original keyway geometry on covered models, allowing direct installation without filing, shimming, or modification
- Broad BW-Series Coverage — fits BW 60 S, BW 65 HS, BW 65 S, BW 65 S-2, BW 75 E, BW 75 S, BW 75 S-2, and BW 90 S walk-behind and light rollers, plus BW 35 and BW 35 W trench compactors
- Torque Transmission Integrity — a properly fitted key locks the rotating assembly so drum drive power transfers cleanly, preventing slippage, vibration, and accelerated wear on the shaft and hub bore
- Genuine Bomag Part — supplied under part number 09181208 as an authentic OEM component, backed by Bomag's production quality standards for small precision hardware
A fitting key is a small but load-bearing component that sits in a machined slot — the keyway — between a shaft and a hub or pulley, locking them together so they rotate as a single unit. Without it, or with a worn or undersized key, the hub can slip on the shaft under load, causing loss of drive, chatter, and rapid damage to the keyway itself. On Bomag walk-behind rollers and trench compactors, the fitting key plays a direct role in transmitting drum or drive-wheel torque; a failed or missing key will render the machine unable to compact effectively and can lead to costly shaft or hub replacement if left unaddressed.
