NTN Bearings are rolling-element bearings manufactured by NTN Corporation, a Japanese bearing manufacturer founded in 1918. NTN is one of the world's largest bearing producers and supplies bearings for automotive, industrial, aerospace, railway, and construction applications.
Main Types of NTN Bearings
Deep Groove Ball Bearings
Most common type.
Suitable for high speeds and moderate radial/axial loads.
Examples: 6203, 6205, 6308 series.
Used in electric motors, fans, pumps, and vehicles.
Angular Contact Ball Bearings
Designed for combined radial and axial loads.
Common in machine tools and automotive transmissions.
Tapered Roller Bearings
Handle heavy radial and axial loads.
Used in wheel hubs, gearboxes, and industrial machinery.
Spherical Roller Bearings
Accommodate shaft misalignment.
Common in mining, crushers, conveyors, and heavy industry.
Cylindrical Roller Bearings
High radial load capacity.
Used in electric motors and industrial equipment.
Needle Roller Bearings
Compact design with high load capacity.
Often found in transmissions and engines.
Thrust Bearings
Primarily support axial loads.
Used in automotive and industrial applications.
Advantages of NTN Bearings
