The Bomag 740052744 Key Block is a genuine OEM component designed for the BM1300/30 and BM1200/30 cold milling machines. Sourced directly from Bomag, this part carries the same specifications as the original, ensuring a direct, correct-fit replacement. This Key Block is the right choice when restoring your milling machine to full operating condition with an authentic Bomag part.
Key Features
- Genuine OEM Specification — manufactured to Bomag's exact original tolerances and material standards, with no deviation from the production-spec component
- Direct Replacement Fit — engineered to install in the same position and orientation as the original Key Block, with no rework or adaptation needed at the mounting interface
- Confirmed Fitment — verified for the Bomag BM1300/30 and BM1200/30 cold milling machines under part number 740052744
- Structural Integrity Under Load — a correctly seated Key Block maintains proper shaft and component alignment within the drivetrain or rotor assembly, preventing positional shift during heavy milling operation
- Protects Adjacent Components — a worn or missing Key Block allows relative movement between mated parts, accelerating wear on shafts, hubs, and housings; replacing it promptly limits collateral damage
A Key Block is a precision-machined locking insert that seats between a shaft and a mating hub or gear, transmitting torque and preventing rotational slippage between the two components. On a cold milling machine like the BM1300/30 or BM1200/30, where the rotor and drive assemblies are subjected to continuous high-load operation, a correctly fitted Key Block is essential for keeping power transfer smooth and consistent. When a Key Block shears, deforms, or works loose, the shaft and hub begin to rotate independently, causing rapid wear, vibration, and potential damage to the surrounding drivetrain components.
