Solid and durable, strong commonality and low noise operation,
can be in high speed operation and easy to install
Needle bearings equipped with fine and long roller (roller
diameter of length, diameter 3 ~ *0 times are rarely more than
5mm), therefore radial compact structure, its diameter and load
capacity and other kinds of bearings, the most small diameter
diam-eter with radial installation, especially for the limited size
of supporting structure.
