N 1013 KPHA/SP
Single row cylindrical roller bearingSingle row cylindrical roller bearings are designed to accommodate high to very high radial loads in combination with medium to high speeds. The SKF assortment includes many designs and variants, such as standard, full complement and high capacity bearings. Depending on the configuration of the outer and inner rings, the bearings are available in locating as well as non-locating designs.
- High to very high radial load carrying capacity
- Low friction
- Long service life
