Press Release Summary:
Suitable for rope wheels and pulleys, NNF Series is sealed on both sides to prevent dust and splash water from entering bearings. Double row full complement bearings are suitable for low to medium speeds and can take up axial forces and tilting moments in both directions. Lubrication holes in outer and inner ring enable re-lubrication through shaft and housing. For corrosion protection, bearings are available with RoHS-compliant, anti-corrosion coating.

NKE Double Row Full Complement Cylindrical Roller Bearings
Locating bearings with maximum load carrying capacity, also under extreme operating conditions
Steyr, Austria, 1 October 2009. Bearing manufacturer NKE AUSTRIA GmbH introduces the NNF series of double row full complement cylindrical roller bearings. This series of bearings features a compact design and maximum load carrying capacity. The bearings are sealed on both sides and suitable for extreme operating conditions. Typical applications for NNF bearings are rope wheels and pulleys.
The maximum radial load carrying capacity of the NNF series cylindrical roller bearings is accomplished through the full complement design, i.e. a maximum number of rollers is fitted within the available cross-section. They are suitable for low to medium speeds and can take up axial forces and tilting moments in both directions. To prevent dust and splash water from entering the bearings, the NNF series is equipped with contacting seals on both sides. A special grease allows the bearings to operate under extreme conditions. Lubrication holes in the outer and inner ring enable easy re-lubrication through shaft and housing.
Rope wheels and pulleys are typical application examples for NNF series double row full complement cylindrical roller bearings. Due to the narrower outer ring, additional sleeves or distance pieces are not required. Two snap ring grooves on the outer ring simplify the bearing arrangement design for sheaves. For better corrosion protection, the bearings are also available with a special, RoHS compliant anti-corrosion coating SQ171. Black oxide coating can also be realised to optimise the tribological characteristics of the bearings. Furthermore, the bearings can be manufactured in application specific clearance and tolerance classes.
