Structure and Adaptability Characteristics
Protection and Support: The cylindrical structure encloses the steering shaft, isolating it from external dust, mud, and other contaminants, while providing radial support to prevent shaft bending and deformation, ensuring steering precision (Cat®…).
Vibration Reduction and Noise Reduction: The EPDM rubber material effectively attenuates steering system vibration, reduces steering wheel vibration transmission, improves operating comfort, and is suitable for bumpy working conditions in construction machinery (Cat®…).
Integrated Adaptation: The flange structure at both ends is used for fixing to the chassis and steering column, compatible with the installation and wiring of control components such as steering switches and horn switches, without interfering with steering operation (Cat®…).
