Features:

Single row cylindrical roller bearings with cage are units comprising solid inner and outer rings together with cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact with each other during rolling.

The cage type bearings are very rigid, can support high radial loads and, due to the cage, are suitable for higher speeds than the full complement designs. Bearings with the suffix E have a higher capacity roller set and are thus designed for very high load carrying capacity.

The bearings are separable and are therefore easier to fit and dismantle. Both bearing rings can be given a tight fit by this process.
Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings.

Application: cylindrical roller bearing will working application: Cable Stranders,Worm gear, Screw Drives, Turbine engine mainshafts, Transmissions, largesize generators, machine tool spindles, axle boxes,bent axles of diesel engines, gearboxes, Mechanical presses, Electrical motors, Pumps and compressors, Traction motors for railway vehiches, Axle boxes for railway vehicles, Steel mills, And so on.
