Machined Type Needle Roller Bearings are bearings with a low sectional height and large load ratings The outer ring has high rigidity and can easily be used even for light alloy housings These bearings are available in metric series and inch series both of which have the caged type and the full complement type

Needle roller bearings are rotational motion bearings in which a thin needleshaped roller is incorporated into a rolling element They have a low crosssection height and high load capacity compared with ball bearings Being small needle roller bearings contribute to reducing overall machine size and are thus widely
