It is usually formed with thin steel plate through precision punching with very sectional height and big load capacity, so it is suitable for the needed of the low cost and mass produced.
Drawn cup needle roller bearing is used between the needle bearings and the bearing cage, and no axial fixture device is required. Even under the condition of high speed and heavy load, the original function of the bearing can be fully maintained, and not to be easily damaged. Due to the high storage volume of grease, the drawn cup needle roller bearing possibly without lubricating for a long time.
