Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
We supplies needle roller bearings in different designs and a wide range of sizes, which are appropriate for different applications. In addition to customized designs, they comprise the following types and components:
Needle roller and cage assemblies
Needle roller bearings with machined rings with flanges
Alignment needle roller bearings
Inner rings for needle roller bearings
