Stamped Outer Ring Needle Roller Bearings
Stamped outer ring needle roller bearings are used for equipment where installation space is limited and housing holes are not suitable as raceways
The stamped outer ring needle roller bearing is a combination, there are two types of open and closed type. The assembly comprises a thin-walled stamped outer ring, a needle roller and a cage assembly.
The outer ring of the needle roller bearing is precisely stamped with thin steel plate, which has small structural space and large load capacity. It is suitable for occasions where installation space is limited and housing holes are not suitable for raceway. Further axial positioning is not necessary after pressing into the bearing seat hole.

There are two types of stamped outer ring needle roller bearings: closed and open.
1. Closed stamped outer ring needle roller bearings
The outer ring of the closed stamped outer ring needle roller bearing is installed with a wrap closure cover to form an effective sealing gap between the needle roller and the cage, which can prevent dust, water, oil and other impurities from invading the bearing interior. Closed stamped outer ring needle roller bearings are suitable for some environments that require sealing protection.
2. Open stamped outer ring needle roller bearings
The outer ring of open stamped needle roller bearing is not equipped with a closed cover, and the needle roller and cage are directly in contact with the external environment. Open stamped outer ring needle roller bearings are easier to maintain and clean than closed bearings, but they are also more susceptible to the external environment.
1. High load capacity: Stamped outer ring needle roller bearings are known for their small tangential size and high load capacity. Because the needle roller is longer, it can withstand higher radial loads and smaller axial loads.
2. Compact size: The size of the stamped outer ring needle roller bearing is smaller than other bearings, and this type of bearing can be selected when the installation space is small.
3. Strong adaptability: stamped outer ring needle roller bearings can be adapted to rotating parts in various machinery, such as actuators, retarders and motors.
4. Uniform load distribution: Due to their design characteristics, the stamped outer ring needle roller bearings can evenly distribute the load on the contact line, so that the friction coefficient is small, so that the operation is more stable.
In short, the stamped outer ring needle roller bearing is a high quality bearing type, because of its special design and superior performance, has been widely used.
