Needle Bearings
1. The needle bearing is a kind of roller bearing that can only bear radial loads, because the diameter of its rolling element is less than 5mm. With compact structure, it is especially suitable for limited installation dimension applications in a radial direction.
2. This product can be categorized into radial type and thrust type. The radial bearing is further divided into drawn cup needle roller type and entity type. A cage of the thrust type has gone through a steel-plate precision stamping process. High-precision needle is assembled in a cage, featuring high strength and wear resistance.
3. The drawn cup needle roller bearing has unique structure. Its outer ring is made from special alloy steel plate. Therefore, this kind of product can offer strong wear-resisting property and high load capacity.
4. The entity type needle bearing gives a wide range of applications due to high accuracy, small footprint, and high load-carrying capacity.
Applications
1. A combination of double-row needle and cage is used extensively in car gearbox.
2. Needle bearings with stud shaft are broadly applicable to conveyor belts and mining industry. The sliding wheel shaft of a crane is also selectable.
3. This kind of product is often used in various industries including the small engine crankshaft, piston pin, air pump, hydraulic pump, printing machinery, and the woodworking machinery.
