Product Details

Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter.

In spit 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.

The outer rings of this needle bearings and bearings case are interference fitted without axial fixed settings.

The effcient capacity can be maintained even if in the condition of high speed and huge loading capacity
