Needle bearings:
The needle and cage assembly is a single or double-column unit consisting of a cage and a needle.Because its radial section is not as large as the diameter of the needle roller, the needle and cage assembly allows the bearings to be arranged through a very small radial design envelope.It has very high load capacity, suitable for high speed and easy to install.
