XTB drawn cup needle roller bearings is formed with thin steel plate through precision punching with very sectional height and big load capacity. This kind of bearings are especially applicable to the big quantity production with economic demands. Stable combination is used between the needle bearings and the bearing cage. No axle fixture is required. Even under high speed and heavy load condition, the bearing functions can be fully maintained. Furthermore, no lubricating for a long time is possible due to its high storage volume of grease.
