Needle roller and cage assembly for small end connecting rods
The small end of connecting rods are subjected to high impact
loads and high-speed oscillation. To address this condition,
these bearings boast a unique light-weight high-strength design.
In addition the cage bore surface is precision-finished so that
the assembly maintains an appropriate cage-riding clearance.
The cage is made from high tensile special steel and the cage
surface is hardened.
The cage is bore-guided and the guide surface is designed to
be as long as possible to minimize surface pressure.
Rollers with the longest possible length are used, At the same
time, the maximum number of smaller diameter rollers are
incorporated in order to reduce the contract pressure on the
rollers.
