Bearings

• Ball Bearings
• Cylindrical Roller Bearings
• Tapered Roller Bearings
• Spherical Roller Bearings

Bearings are classified according to:

The motions allowed, or
The directions of the loads or forces applied to the parts

Classification according to design:

Rolling bearings contains rolling elements – balls, cylindrical rollers, spherical rollers, needle rollers, tapered rollers.
Plain bearings are those without rolling elements.

Classification according to the dominant direction of transmitted forces:

Rolling bearings contains rolling elements – balls, cylindrical rollers, spherical rollers, needle rollers, tapered rollers.
Plain bearings are those without rolling elements.
