Cylindrical Roller Bearings
Cylindrical roller bearings are manufactured in a various range of types and sizes, frequently single row cylindrical roller bearings but also in configurations of two rows or more. In cylindrical roller bearing designs, the rollers are laterally guided by the fixed ribs of one ring. In case of bearings with cages, the ring with ribs and rollers retained in the cage can be drawn out from the other ring, which means that these bearings are dismountable. Roller bearings typically have higher load capacity than ball bearings, but a lower capacity and higher friction under loads perpendicular to the primary supported direction. The four basic designs (NU, NJ, N and NUP) are determined by the function of the inner and outer races.
• Extra Capacity – Extra capacity cylindrical roller bearings feature high load ratings. They are quiet running with a precision machined tough one-piece cage for all industrial applications. They have an extra capacity internal design with higher load ratings compared with conventional bearings. Extra capacity roller bearings provide up to twice the bearing life and higher load rating compared with conventional bearings.
• Cylindrical Roller Thrust – Cylindrical roller thrust bearings are generally intended to take heavy pure axial loads. They can also better handle shock loads. Cylindrical roller type thrust bearings are available with single or multiple rows of rollers.
