The Bomag 05311012 Grooved Nut is a genuine OEM component designed for Bomag pneumatic tyred rollers and single drum rollers, including the BW 24 R, BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC, BW 28 RH, BW177PDH 5, and C 560 B. Sourced directly from Bomag, this grooved nut matches the original factory specification for a precise, trouble-free installation. Replacing a worn or damaged grooved nut with a genuine OEM part ensures your machine maintains correct clamping, preload, and alignment throughout its service life.
Key Features
- Genuine OEM Thread Integrity — manufactured to Bomag's exact thread form and groove profile, ensuring proper torque retention and secure locking without distortion under load
- Direct Drop-In Replacement — matches the original fastener dimensions and groove geometry so this grooved nut seats and locks exactly as the factory-installed part did
- Broad Fitment Coverage — confirmed fit across Bomag BW-series pneumatic tyred rollers including the BW 24 R, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC, BW 28 RH, BW 25 RH, BW 24 RH, BW177PDH 5 single drum roller, and C 560 B pneumatic tyred roller
- Consistent Clamping Performance — a correctly fitted grooved nut maintains bearing preload and shaft alignment, preventing premature wear to surrounding components and keeping assemblies running true
- Verified by Part Number 05311012 — cross-reference part number 05311012 against your machine's service manual or parts diagram before ordering to confirm application
A grooved nut is a precision locking fastener used to secure bearings, hubs, and rotating assemblies on a shaft. The circumferential groove is designed to accept a locking tab or retaining clip that prevents the nut from loosening under vibration and cyclic loading — conditions that are constant on compaction equipment. When a grooved nut wears, strips, or is incorrectly torqued, bearing preload is lost, which accelerates wear on adjacent components and can lead to shaft play or assembly failure. Using a genuine Bomag replacement ensures the correct thread engagement and groove depth are maintained every time.
