Needle Roller Bearings

Needle roller bearings are widely used industrial rolling bearings with compact structure, small radial size and extremely high load capacity. Compared with standard ball bearings, needle roller bearings can bear larger radial pressure in limited installation space, providing stable rotation, low friction and long service life for various mechanical transmission systems.

Our factory provides a complete range of needle roller bearings and track roller bearings, including yoke type support rollers, stud type cam followers, needle roller cage assemblies, inch size bearings and customized non-standard bearings. All products are manufactured according to ISO standards and fully interchangeable with international famous brands.

Main Product Models
