Please verify OE number, dimensions and vehicle configuration before ordering.
Product Features
- NU design – two integral flanges on the outer ring and no flanges on the inner ring – accommodates axial displacement in both directions while supporting high radial loads.
- Separable design simplifies mounting and maintenance – the inner ring can be removed independently.
- Open-type configuration supports splash lubrication and oil bath systems common in transmission and gearbox applications.
- Heat-treated GCr15 bearing steel construction with precision-ground raceways delivers rated dynamic load of 75 kN and static load of 63 kN.
- Interchangeable with SKF NU 307 ECP, FAG NU307, and INA Z51014802 – confirmed cross-reference available.
Installation Notes
- Confirm bore diameter (35.00 mm) and outer diameter (80.00 mm) match your existing bearing and housing before installation.
- This bearing is of NU design – the inner ring is separable and can be mounted separately from the outer ring and roller assembly.
- Inspect the shaft and housing for wear or damage – replace if scoring or pitting is present.
- Apply appropriate lubricant (oil or grease) during installation – refer to your equipment manual for viscosity specifications.
- Ensure proper shaft and housing tolerances – cylindrical roller bearings require accurate fits for optimal load distribution and service life.
