Cylindrical roller bearings have a high radial load capacity and a low thrust load capacity. They have cylindrically formed rollers, but they are not genuine cylinders.
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 cages can accommodate heavy radial loads, rapid accelerations and high speeds.
Full complement bearings (without cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds
