NUP 226 ECJ
Single row cylindrical roller bearing, NUP design
Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds.
Having two integral flanges on the outer ring and one integral flange and one loose flange ring on the inner ring, NUP design bearings can locate the shaft axially in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
- High radial load carrying capacity
- Low friction
- Long service life
- Locate the shaft axially in both directions
- Separable design
