İBearing is the part of a machine, which makes relative motion to only the desired motion, and reduces friction between moving parts.
While bearings classfied as ball bearing or roller bearing according to the rolling element between inner and outer ring. In addition to that classification, bearings can defined radial or axial according to the loads they carry.

Ball Bearings
• Deep Groove Ball Bearings
• Angular Contact Ball Bearings
• Self- Aligning Ball Bearings
• Thrust Ball Bearings

Roller Bearings
• Tapered Roller Bearings
• Spherical Roller Bearings
• Cylindirical Roller Bearings
• Needle Roller Bearings

Bearings are in every rotating mechanism, which we encounter frequently in our daily lives. Bearings are used in all areas of life such as; automotive, machine industry, mining, agriculture, aerospace, energy.
