Needle roller and cage assemblies of
Tungpei. Needle roller bearings have relatively smaller diameter cylindrical
rolling elements whose length is much larger that their diameter.Compared with
other types of rolling bearings, needle roller bearings have a small
cross-sectional height and significant load-bearing capacity and rigidity
relative to their volume. Also, because the inertial force action on them is
limited, they are ideal choice for oscillating motion. Needle roller bearings
contribute to compact light weight machine designs. They serve also as a ready
replacement for sliding bearings.
