    Singel row & Double row full complement cylindrical roller bearings have solid outer and inner rings together with rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity, 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. Single row full complement cylindrical roller bearings are in the form of semi-locating bearings.

    Cylindrical roller bearings SL0148(designation to DIN 5412-9:NNC 48..V) and SL0149(designation to DIN 5412-9:NNC 49..V) are double row locating bearings,these bearings can support axial forces from both directions as well as radial forces.
     
    Caution!
      The outer ring has ribs on both sides,is axially split and held together by fasteners.the inner ring has an additional central rib.the fasteners must not be subjected to axial load.
      Sealing/lubricant
      The cylindrical roller bearings are not sealedd and not greased.they can be lubricated with oil and grease.
      For lubrication,the outer ring has a lubrication groove and lubrication holes.
     
    Non-locating bearings
      Bearings SL0248(designation to DIN 5412-9:NNCL 48...V) and bearings SL0249(designation to DIN 5412-9:NNCL 49...V)  are double row non-locating bearings and can support radial forces only.
     
    Axia displacement
      The outer ring without ribs can be axially displaced in both directions in relation to the inner ring.The inner ring has ribs on both sides.
     
    Caution!
      The bearings are held together in handling and transport by a transport and mountin retaining device.this retaining device must not be subjected to axial load.
