A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers looking like sewing needles. Rollers of ordinary roller bearings are only slightly longer than their diameter, but needle rollers are at least four times longer than their diameter. Like all the other bearings, they are used to reduce the friction of rotating surface.Needle roller/rolling bearings specifications
