Needle roller bearing RNA5007

The needle Roller Bearing of stamping outer ring is a needle roller bearing with thin forming outer ring. Its main characteristic is the section height is very low and bears the load ability high. It is mainly used for the bearing configuration of compact structure, cheap price and the inner bore of bearing box can not be used as the raceway of needle holder assembly. The bearing and bearing box shall be fitted by interference fit. If the axial positioning function such as the shoulder and stop ring can be omitted, then the inner bore of the bearing box can be made extremely simple and economical. The press outer ring needle bearing mounted on the shaft end has two sides open type and one side closed type. The base end of the closed punching outer ring can withstand less axial guiding force. Press the outer ring needle bearing generally does not attach inner ring. In cases where the journal is not hardened or ground, the inner ring listed in the table may be used. The hardened steel plate outer ring of the stamping outer ring needle bearing is inseparable from the needle holder assembly. The free space for storing lubricants can extend the supplemental lubrication interval. Bearings are generally designed in a single column. Except for the wider bearing series 1522,1622,2030,2538 and 3038, they are fitted with two needle cage assemblies. The bearing outer ring has lubrication holes. According to the user's requirements, all single row stamping outer ring needle bearings with diameters greater than or equal to 7mm can be equipped with outer ring with lubricating oil hole (code suffix AS1). Provided with an open end or a closed end with an oil seal outer ring needle roller bearing (3 to 5) when an oil seal outer ring needle bearing cannot be installed due to space limitations. This type of bearing seal equipment of polyurethane or synthetic rubber friction, which have good rust resistance of lithium base grease filling, applicable operating temperature - 20 to + 100 ℃. The inner ring of the oil-seal bearing is 1mm wider than the outer ring, which makes the bearing can also ensure the oil seal to work well and avoid bearing pollution when the bearing is slightly displaced relative to the bearing box. The inner ring of the bearing is also provided with lubrication holes, which can be lubricated by the outer ring or inner ring according to the requirements of bearing configuration.
