Do you want to learn about the stamped outer ring cylindrical needle roller bearing?

The cylindrical needle roller bearing is a needle roller bearing with a thin stamped outer ring. The main feature of the cylindrical needle roller bearing is that the section height is very low and the load capacity is high. Mainly used for bearing arrangements that are compact, inexpensive, and the bore of the bearing housing cannot be used as the raceway for the needle roller cage assembly. The bearing and bearing housing must be installed in an interference fit. If the axial positioning function such as the box shoulder and the stop ring can be omitted, the inner hole of the bearing housing can be made extremely simple and economical. The cylindrical needle roller bearing mounted on the shaft end has a double-sided open type and a single-sided closed type. The base end face of the closed stamped outer ring can withstand small axial guiding forces.

Cylindrical needle roller bearing is generally not attached to the inner ring. In the case where the journal cannot be hardened and ground, the inner ring listed in the table can be used. The outer ring of the hardened steel plate of the cylindrical needle roller bearing is inseparable from the needle roller cage assembly. The free space to store the lubricant can extend the relubrication interval. Bearings are generally designed in a single row. Except for the wider series of bearings 1522, 1622, 2030, 2538 and 3038, they are equipped with two needle retainer assemblies. The outer ring of the cylindrical needle roller bearing has a lubricating oil hole. All single row drawn cup needle roller bearings with a shaft diameter greater than or equal to 7 mm can be equipped with an outer ring with a lubrication hole (code suffix AS1), depending on the user's needs.

Cylindrical needle roller bearing with oil seal stamping outer ring can provide open or closed end oil seal stamping outer ring cylindrical needle roller bearing. These bearings are equipped with a polyurethane or synthetic rubber friction seal that is filled with a lithium-based grease with good rust resistance and is suitable for operating temperatures from -20 to 100 °C. The inner ring of the oil-sealed bearing is 1 mm wider than the outer ring. This makes the bearing work well in the case of a slight displacement of the bearing shaft relative to the bearing housing without causing the bearing to be contaminated. The inner ring of the cylindrical needle roller bearing also has lubrication holes, which can be relubricated by the outer ring or the inner ring according to the needs of the bearing arrangement.
