Production function:

Drawn cup needle roller bearings are needle roller bearings with thin stamped and formed outer rings. Its main feature is that the section height is very low and the load bearing capacity is high. It is mainly used for the bearing configuration with compact structure and low price, and the inner hole of the bearing box cannot be used as the raceway of the needle roller cage assembly. The bearing and the bearing housing must be installed in an interference fit. If axial positioning functions such as box shoulder and stop ring can be omitted, the inner hole of the bearing box can be made extremely simple and economical. The drawn cup needle roller bearings mounted on the shaft end have double-sided open type and single-sided closed type. The base end face of the closed drawn outer ring can bear little axial guiding force. Drawn cup needle roller bearings generally do not have an inner ring.
