Product Description
Super Precision Double Row Cylindrical Roller Bearing
Super-precision double row cylindrical roller bearings in the NN 30 series provide an optimal balance between load carrying capacity, rigidity, and operational speed. Featuring three flanges on the inner ring and no flanges on the outer ring, these bearings accommodate axial displacement in both directions. The separable design simplifies installation and removal, particularly when both rings require interference fits.
Key Features & Benefits
- Very high radial load carrying capacity
- High rigidity and exceptional running accuracy
- Minimized noise, vibration, and heat generation
- Axial displacement accommodation in both directions
- Integrated lubrication feature for extended service life
- Tapered bore (1:12) enables precise clearance or preload adjustment
