cylindrical roller bearings are available in many designs, series and sizes. The major design differences between the bearings presented in this section are in:

• the number of roller rows (one, two or four)


• the type of cage (with, without or special designs)




• Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds.


• Full complement bearings (without a cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.


• high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage.




• the configuration of the inner and outer ring flanges (position and number of guide flanges)
