The Bomag 315121144 Grooved Ball Bearing is a genuine OEM component designed for Bomag BM-series cold milling machines and BF-series pavers. Sourced directly from Bomag, this bearing meets the original engineering specification for precision tolerancing and dimensional accuracy. It fits a wide range of machines, including the BM 1200/30, BM 1300/30, BM 1000/30-2, BF 600 C-2 S 500, BF 700 C-2 S 500, BF 800 C S600, BF 900 C S600, and many additional BF-series paver configurations. When you order part number 315121144, you are getting the exact component Bomag specifies for these machines.
Key Features
- OEM Precision Tolerancing — manufactured to Bomag's original bearing specification, ensuring correct radial and axial load capacity for demanding milling and paving applications
- Direct OEM Replacement — dimensionally identical to the original, this bearing seats and installs exactly as the factory component did, with no re-machining or adaptation
- Broad Fitment Coverage — confirmed fit across BM-series cold milling machines including the BM 1200/30, BM 1300/30, and BM 1000/30-2, and BF-series pavers including BF 600, BF 700, BF 800, and BF 900 configurations
- Sustained Rotational Performance — a correctly spec'd grooved ball bearing keeps rotating assemblies running smoothly under load; a worn or failed bearing causes vibration, heat buildup, and accelerated damage to surrounding components
A grooved ball bearing — also known as a deep-groove ball bearing — supports rotating shafts and spindles by reducing friction between moving parts while carrying both radial and light axial loads. In cold milling machines and pavers, these bearings are found in drive systems, conveyor assemblies, and other rotating mechanisms where consistent, low-friction motion is critical to machine output and accuracy. When a grooved ball bearing wears out or fails, the result is increased vibration, audible noise, elevated heat in the bearing housing, and eventually seizure or damage to adjacent components — making timely replacement essential to keeping the machine productive.
