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.
