Steering Tie Rod End A2123302203 For Mercedes W212 W218-CLS

The outer ball head of the steering machine is an important part in the steering system, and its main components include the following parts:

1. Shell: The shell of the outer ball head is usually made of metal, which is used to protect the inner spherical joint and other parts, and at the same time plays the role of fixing and supporting.

2. Spherical joint: The spherical joint inside the outer ball head is the core component of the outer ball head, usually made of high-strength alloy steel or stainless steel. The spherical joint can rotate and swing in many directions, so that the outer ball head can flexibly connect and transmit steering force.

3. Tighten the nut: it is used to fix the shell and spherical joint of the outer ball head to ensure the stability and safety of the outer ball head. Tightening nuts usually adopt special thread design, which can bear the force and torque generated during steering.

4. Grease: The outer ball head is usually filled with grease to reduce friction and wear and keep the spherical joint running normally. Grease can improve the service life and stability of the outer ball head and ensure the normal operation of the steering system.

5. Seals: The outer ball head is usually equipped with seals to prevent dust, moisture and impurities from entering the outer ball head and protect the spherical joints and other parts from being damaged. The seal can effectively prevent the outer ball head from being affected by external environmental factors.

To sum up, the main components of the outer ball head of the steering gear include shell, spherical joint, tightening nut, grease and seal. These components work together to ensure that the outer ball head can connect and transmit the steering force, and ensure the stability and flexibility of the steering system of the vehicle. Regular inspection and maintenance of the outer ball head is an important measure to ensure vehicle handling performance and safety.
