Features
Full complement cylindrical roller bearings have solid outer and inner rings and rib-guided cylindrical rollers. Since they have the maximum possible number of rolling elements, these bearings have extremely high radial load carrying capacity and high rigidity and are suitable for particularly compact designs. Due to the kinematic conditions, however, they do not achieve the high speeds that are possible when using cylindrical roller bearings with cage.
Full complement cylindrical roller bearings are available as non-locating, semi-locating and locating bearings as well as in single and double row designs.
Non-locating bearings
Bearings SL0248 (designation to DIN 5 412-9: NNCL 48..V) and bearings SL0249 (designation to DIN 5 412-9: NNCL 49..V) are double row non-locating bearings and can support radial forces only.
Semi-locating bearings
Semi-locating bearings are available in single row design as SL1818 (dimension series 18), SL1829 (dimension series 29), SL1830 (dimension series 30), SL1822 (dimension series 22), SL1923 (dimension series 23) and in double row design as SL1850 (dimension series 50).
They can support not only high radial forces but also axial forces in one direction and can therefore guide shafts axially in one direction. They act as non-locating bearings in the opposite direction.
Series SL1923 has only one rib on the inner ring. As a result,the inner ring can be removed from the bearing. This makes fitting and dismantling considerably easier.
Locating bearings
Cylindrical roller bearings SL0148 (designation to DIN 5 412-9: NNC 48..V) and SL0149 (designation to DIN 5 412-9: NNC 49..V) are double row locating bearings. These bearings can support axial forces from both directions as well as radial forces.
Operating temperature
Full complement cylindrical roller bearings are suitable for operating temperatures from –30 °C to +120 °C.
