The essentials of specification table for needle roller bearing with stamping outer ring are expounded.

Under general working conditions, the bearing can be protected from impurities invasion and grease leakage. Compared with perforated punched needle roller bearings, one end of the sealed bearing is sealed, which is suitable for shaft end and can withstand small axial swimming power. It is suitable for situations where installation space is limited and shell hole is not suitable for raceway. Stamping outer ring needle roller bearings are mainly used for compact structure, inexpensive and bearing box bore can not be used as the raceway of needle roller cage assembly. The base end face of closed stamping outer ring can withstand little axial guidance force. Free space for storing lubricant can extend the supplementary lubrication interval.
