The Bomag 05611231 Coupling Ring is a genuine OEM component designed for the BW 90 S walk-behind light roller. Sourced directly from Bomag, this coupling ring matches the original specification for a drop-in installation with no guesswork on fitment. Genuine OEM designation means this part carries the same tolerances and material grade as the component that left the factory floor, keeping your BW 90 S running the way it was engineered to. If your machine is showing signs of drivetrain slippage, vibration, or coupling wear, replacing this part promptly restores smooth power transfer and protects surrounding drivetrain components.
Key Features
- Genuine OEM Torque Coupling Integrity — manufactured to Bomag's original material and dimensional spec, ensuring the coupling ring transmits torque at the correct engagement force without slippage or deformation under load
- Direct OEM Replacement — part number 05611231 matches the original component profile, seating and securing exactly as the factory-installed ring did with no rework required
- Confirmed BW 90 S Fitment — verified for the BW 90 S walk-behind light roller, so you can order with confidence that this is the correct ring for your machine
- Protects Adjacent Drivetrain Components — a worn or cracked coupling ring places stress on connected shafts and housings; replacing it at the first sign of wear prevents costlier secondary damage
- Long-Term Durability Under Compaction Loads — built to withstand the cyclic stress and vibration inherent to vibratory roller operation, maintaining a secure mechanical connection across demanding compaction tasks
A coupling ring serves as the mechanical link between rotating drivetrain components, transmitting torque while absorbing minor misalignment and shock loads. In a walk-behind roller like the BW 90 S, this component is subject to constant vibration and cyclical loading during compaction work. When the coupling ring wears, cracks, or deforms, the connection between drivetrain elements becomes loose or erratic, leading to vibration, noise, loss of drive, and potential damage to shafts and housings. Replacing it with a genuine Bomag part restores the precise mechanical engagement the drivetrain depends on.
