Cylindrical roller bearings with cage

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 are without ribs, the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers coming into contact with each other during rolling.

The cylindrical roller 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 suffix E have a larger roller set and are thus designed for extremely high load carrying capacity.

The bearings can be taken apart and can therefore be fitted and dismantled more easily. Both bearing rings can therefore have an interference fit.

Single row cylindrical roller bearings with cage are available as non-locating, semi-locating and locating bearings.

Product Detail

Cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. There are N type, NU type, NF type, NJ type, NUP type, CL type and RNU type. Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. The cage is made of brass or steel.

The part number followed by a code number”E” means reinforced cylindrical roller bearing.

Radial clearances listed in table are standard ones. DFB can also provide bearings with various clearances.
