Needle bearings are a specialized type of roller bearing that utilize cylindrical rollers distinguished by their slender and elongated design, relative to their diameter. Known as needle rollers, these components boast a high load-bearing capacity despite their smaller cross-section. Featuring thin and long rollers (roller diameter D≤5mm, L/D≥2.5, with L representing the roller length), the radial structure remains compact. In comparison to other bearings with the same inner diameter and load capacity, needle roller bearings possess the smallest outer diameter, making them ideal for support structures where radial installation space is at a premium.
At Shandong Allfine Auto Parts Co., Ltd., we proudly manufacture an extensive array of needle roller bearings, including the following series:NK Series: Models include NK5/10, NK12/16, NK20/20, and more.NA Series: Models include NA4900, NA6901, and others.
RNA Series: Models include RNA4901, RNA6910, among many others.
NKI Series: Models include NKI10/16, NKI25/30, etc.
K Series: Models such as K5x8x8TN, K32x37x13, and more.
AXK Series: Models like AXK0619, AXK1226, and so forth.
