Drawn cup needle roller bearings 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.
