Needle Roller Bearings

Listing ID #3182416

Needle Roller Bearings are roller bearings with cylindrical rollers, which are thin and long in relation to their diameter (needles). In spite of their low cross section, the bearings have a high load carrying capacity and are thus eminently suitable for bearing arrangements where radial space is limited.
Needle Roller Bearings are used with and without inner ring.
Needle Roller Bearings only permit axial movement between shaft and housing, within certain limits. They are designed for bearing applications when grinding or hardening of the shaft is not possible or economically reasonable. If grinding and hardening of shaft is possible Needle Roller Bearings without inner ring are used. Due to non-availability of inner ring, shaft can be designed stronger and more rigid.
One further version is the Needle Roller Assembly, which is used as rolling element without inner and outer ring.
