Strut Mount Core & Outer Tube: Huami Machining Core Products
1. What are Strut Mount Core and Outer Tube?
The core pin and outer tube are the critical machined components of a strut mount assembly. They determine the performance and service life of the entire mount.
- Core/Center Pin: The metal shaft inside the mount that bears radial and axial loads from the shock absorber piston rod.
- Outer Tube/Sleeve: The metal tube that bonds with rubber to form the mount body, providing support and positioning.
These parts are precision-machined from steel or alloy materials. Dimensional accuracy directly affects assembly and performance.
