Product Description



Descriptions of needle roller bearing RNA4834:

Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.

The outer rings of this needle bearings and bearings case are interference fitted without axial fixed settings. The effcient capacity can be maintained even if in the condition of high speed and huge loading capacity.




Needle roller bearings are a bearing that is classified as either radial or thrust depending on the direction of the load being supported. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam followers, and roller followers. Thrust bearings include thrust needle bearings.




- Smaller cross-section leading to greated rigidity,higher load-carrying capacity & lower inertia of the needle roller bearings help size and weight reductions in machinery.


- Though they are less wide,their load carrying capacity is high and is most suitable for applications where the load is high & the radial space is less.


- Needle roller bearings,which are designed to withstand oscillation can operate under severe conditions & interchange with sliding bearings.

Method of extending the bearing’s lifetime:

1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.


2. Don't allow strong impact, such as hammer striking, transfer roller pressure 


3. Use the accurate installation tool, avoid to use cloth kind and short fibers


4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer


5. General inspection, such as the surrounding temperature, vibrate, noise inspection


6. Keep bearing cleaning from dirt, dust, pollutant, moisture.


7. Bearing should not be ultra cooled.
