Roller bearings are used to replace sliding movement with low friction, rolling motion in rotary applications. The principal types of roller bearings are cylindrical, spherical, and tapered. In general, roller bearings offer higher load capacities than ball bearings of the same size.

ATO.com offers needle roller bearings, track roller bearings, tapered roller bearings, cylindrical roller bearings and spherical roller bearings for selection. The roller bearings are used for heavy-duty moderate-speed applications. Potential applications for spherical and cylindrical roller bearings include power generation, oil field, mining and aggregate processing, wind turbines, gear drives, rolling mills. Single-row tapered roller bearings are used in such applications as machine tool spindles, gear reduction units, automotive transaxles, transmissions, vehicle front wheels, differential and pinion configurations, conveyor rolls, machine tool spindles, and trailer wheels.

Types of Roller Bearings

There are five main types of roller bearings:

Cylindrical Roller Bearings have high radial-load capacity and moderate thrust loads. They contain rollers that are cylindrically-shaped, but crowned or end-relieved to reduce stress concentrations. Cylindrical roller bearings are similar in design to needle roller bearings but the dimensions of diameter and roller length are closer in magnitude.
Spherical Roller Bearings are self-aligning, double row, combination radial and thrust bearings. They use a spherical or crowned roller as the rolling element.
Tapered Roller Bearings consist of an inner ring (cone), an outer ring (cup), a cage and rollers, which are profiled to distribute the load evenly across the roller. During operation, tapered roller bearings create a line contact between the raceway and rolling element, distributing loads across a larger area.
Needle Roller Bearings are a type of cylindrical roller bearing where the length of the roller is much larger than then the diameter. Needle roller bearings are designed for radial load applications where a low profile is desired.
