Ball and Roller Bearings

Deep groove ball bearings, miniature and extra small bearings, angular contact bearings, self-aligning ball bearings, cylindrical roller bearings, tapered roller bearings, spherical roller bearings, thrust bearings, special application bearings. (Ref. catalog "Ball and Roller Bearings" CAT. No. 2202/E etc.)

Needle Roller Bearings

Needle roller bearings have a cylindrical needle-type roller with a comparatively small diameter, where the length is greater than the diameter. Needle roller bearings have small cross-sectional height, and compared with other types of bearings, feature high load capacity and rigidity compared to the space taken by the bearing. Another feature is the low inertial force, which is appropriate for oscillating motion. Using these bearings, it is possible to make mechanical equipment smaller and lighter in weight. Also, it is easy to replace a sliding bearing with a Needle roller bearing. (Ref. catalog "Needle Roller Bearings" CAT. No. 2300/E etc.)

Large Bearings

In JIS standards, bearings with a diameter of 180mm or more are called large bearings. At NTN, we have a proven record with various models -- among which are bearings with an outer diameter exceeding 5 m, and single bearings with a load capacity in excess of 14,000 tons. (Ref. catalog "Large Bearings" CAT. No. 2250/E etc.)

Bearing Units

NTN bearings units combine a double-sealed ball bearing with various types of bearing housing. These are optimal units which are self-aligning at the spherical fitting surface of the bearing and housing. In particular, set screw type bearing units use NTN's unique set screw with a ball, and this is extremely effective for stopping loosening of the set screw, even when there is a vibrating or impact load.
