NTN FAQ
Where is NTN based?
NTN Corporation is headquartered in Osaka, Japan, with global plants in Japan, China, Thailand, the US, Germany and France. NTN-SNR is the European arm of the group.
What is NTN known for?
World #1 in automotive CV joints, plus a strong position in wheel hub units, tapered roller bearings and agricultural pulley bearings. Wide deep-groove and spherical roller catalogue too.
How does NTN differ from KOYO/JTEKT?
Both are Japanese, but NTN dominates CV joints and wheel hubs, while KOYO (now JTEKT) is strongest in Toyota Group automotive steering and tapered roller bearings. Same nominal part numbers can carry different default greases and clearances.
How do I quote a wheel hub unit?
Provide vehicle make, model, year, drive type (2WD/4WD) and front/rear position. Wheel hub units integrate the bearing, hub flange and (often) the ABS sensor, so the vehicle context determines the right NTN part number.
