Q: Which country are NTN bearings from? What bearings does it produce?
A: NTN is a global precision bearing manufacturer, founded in Japan in 1918. NTN produces a full range of bearings and related products, including commonly used ball bearings (deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, etc.), roller bearings (cylindrical roller bearings, tapered roller bearings, self-aligning roller bearings, etc.), needle roller bearings (needle roller bearings, combined bearings, roller bearings, cam followers, etc.), bearing housings (ball bearing housings, roller bearing housings), and bearing accessories (adapter sleeves, lock nuts, lock washers, lubrication and installation tools, etc.), which can meet almost all bearing needs.
Q: What are NTN's advantageous products?
A: NTN has significant advantages in insulated bearings, precision bearings, spherical roller bearings, and bearing housings. These include: ULTAGE series precision angular contact ball bearings and precision cylindrical roller bearings; Megaohm series insulated deep groove ball bearings and insulated cylindrical roller bearings; KIZEI series sealed spherical roller bearings and ULTAGE series spherical roller bearings; and various series (approximately ten types) of bearing housings.
Q: Does NTN Bearings have a factory in China?
A: NTN Bearings also has factories in Shanghai and Nanjing, primarily producing some cylindrical roller bearings (double-row cylindrical roller bearings for pulleys) and tapered roller bearings. Chinese-made NTN bearings have the suffix U0NZ. Generally speaking, Chinese-made NTN bearings are slightly cheaper than Japanese-made NTN bearings (approximately 30% cheaper). However, there are exceptions. For example, some pulleys use double-row cylindrical roller bearings, where Chinese-made bearings are more expensive. I'm not sure why this is the case.
