Automobile Part QJ109EZ Four-point Contact Ball Bearing

⚙️Core technical features:

High precision and low friction performance:

The pre-loading design with nearly zero axial clearance enables a balance between low torque operation and high rigidity, significantly reducing the operating resistance of the steering system. Combined with the ZZ sealing structure, it can effectively prevent dust, oil stains, and other contaminants.

Self-lubrication and durability upgrade:

The bearings have self-lubrication properties and can adapt to high-speed conditions without frequent maintenance. Under grease lubrication, the maximum rotational speed can reach 2860 rpm, and with oil lubrication, it can be increased to 8736 rpm. In terms of materials, the use of fully quenched bearing steel enables the bearing to have a rated dynamic load of 80 KN and a rated static load of 83 KN, capable of withstanding an axial separation load of 10 KN.

Installation compatibility advantages:

The standardized size design allows for direct assembly without additional processing of the shaft or housing, significantly simplifying the maintenance process.

⚙️Product Application:

Primarily used in the steering system of automobiles, as the steering bearing of the steering wheel, it can also be applied to other automotive components with high requirements for rotational accuracy and stability, such as the transmission. can also be used in non-automotive scenarios such as mechanical repair shops and farm equipment, etc.

 

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
