Product Description

The 3309 ATN9 is a dual row angular contact ball bearing that corresponds to a pair of single row angular contact ball bearings in a back to back configuration in design and operation, while requiring smaller axial space. They can operate at high speeds and are more suitable for supporting large axial forces acting in both directions than deep groove ball bearings.

The following are the parameters and usage instructions for this type of bearing in general:



Parameters:

-Dimensions: Inner diameter is 45 mm, outer diameter is 100 mm, and width is 39.7 mm.

-Material: Common materials are chromium steel (GCr15) or stainless steel.

-Load capacity: able to withstand high radial and axial loads.

-Speed limit: The specific speed limit depends on load, lubrication, and other factors.



Instructions for use:

-Installation: Before installation, ensure that the bearing seat and journal surfaces are clean and pay attention to the correct installation direction.

-Lubrication: Bearings require appropriate lubrication to reduce friction and wear, and extend their service life. Please refer to the lubrication guide and select the appropriate quantity and type of lubricant.

-Maintenance: Regularly check the condition of bearings and promptly handle any abnormalities. Depending on the usage conditions, it may be necessary to relubricate or replace the bearings.
