Heavy Duty Needle Roller Bearings

ZHIO® Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter but long in length (L/D≥2.5). ZHIO® Needle roller bearings have a high radial load carrying capacity. And since they have a low cross section, needle roller bearings are extremely suitable for bearing applications where the radial space is limited.

ZHIO® offers a wide range of needle roller bearings including needle roller & cage assemblies, drawn cup and solid needle roller bearings. They can also be specified as cam followers and track roller bearings by applications. The major application markets include automotive, consumer product and general industrial goods.
