FeaturesSuper Precision Needle Rollers are designed specifically to handle large radial loads in high-speed spindle applications that demand high running accuracy (runout) of bearing-spindle arrangements.ApplicationIt is widely used in auto, lathe, metallurgical, textile, printing industry & other various machinery equipment.Packagepallet, wooden case,industrial package or as customers' requirementPriceFOB, CFR, CIFDelivery Time5-10 days
