Needle Non Thrust Roller Bearings

Needle roller bearings have relatively small diameter cylindrical rolling elements whose length is much larger than 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 forces acting on them is limited, they are an ideal choice for applications with oscillating motion. Needle roller bearings also work well in compact and lightweight machine designs and they serve as a ready replacement for sliding bearings

This product boasts a unique light-weight high-strength design to cope with crank motion involving the simultaneous rotation and revolution on the large-end side of connecting rod. At the same time, the outer diameter of the cage surface is precision-finished so that the assembly maintains the appropriate cage-riding clearance. The cage is made of high-tensile special steel with a surface hardened treatment. The assembly uses an outer diameter-guided system. ¡If an application has poor lubrication, the cage can be protected with a surface treatment using a non-ferrous metal. For applications with a one-piece crank shaft, split-type cage design is also available.
