The Bomag 09181281 Fitting Key is a genuine OEM component designed for the BW 55 E walk-behind roller. Sourced directly from Bomag, this fitting key matches the original part in every dimension, ensuring it seats and engages exactly as intended on the BW 55 E. When a worn or damaged fitting key is left in service, it can compromise shaft and hub alignment, leading to accelerated wear on surrounding drivetrain components — making timely replacement essential.
Key Features
- OEM-Matched Tolerances — manufactured to Bomag's original dimensional specifications, so the key engages its keyway with the correct interference fit and transmits torque without play or slippage
- Direct Drop-In Replacement — engineered to replace the original fitting key on the BW 55 E walk-behind roller with no modification to the shaft, hub, or keyway
- Confirmed BW 55 E Compatibility — verified fitment for the Bomag BW 55 E walk-behind roller, so you can order with confidence knowing this is the correct part for your machine
- Protects Surrounding Components — a correctly fitted key maintains proper shaft-to-hub coupling, preventing the fretting and keyway damage that develops when an undersized or worn key is left in place
- Genuine Bomag Quality — as an authentic OEM part, this fitting key is produced from the same material grade and to the same finish standards as the key your roller left the factory with
A fitting key is a small but critical power-transmission component seated in a keyway between a rotating shaft and a hub or pulley. Its job is to lock the two together so torque is transferred evenly without the hub spinning freely on the shaft. When a fitting key wears, shears, or goes missing, the hub loses its positive drive connection — causing slipping, uneven compaction output, and rapid damage to the keyway itself. Replacing a worn key promptly with the correct OEM part restores full torque transfer and protects the shaft and hub from costly secondary damage.
