MERCEDES-BENZ (Imported) - S-Class (W140) - 300 SE, SEL/S320 (140.032, 140.033) [M 104.990;M 104.994] (1991.03 - 1998.10)
The Multi-Stage Buffer Suspension Control Arm Bushing for Mercedes-Benz is a composite outer diameter bushing designed for Mercedes-Benz suspension systems. Its core feature is a stepped structure with two outer diameter sizes: 40mm and 25mm. This allows for varying degrees of locking force at the mounting site and multi-stage buffering across different force amplitudes. The 38mm thickness combined with a 12mm precision inner diameter helps guide the swing arm's movement. This highly functional part aims to finely tune chassis response.
Stepped Outer Diameters: 40mm and 25mm specifications.
Core Thickness: 38mm overall.
Precision Connection: 12mm inner diameter ensures bolt stability.
Geometry: Combined parameters of 40mm * 37.9mm * 12mm.
Composite Design: Leverages diameter differences for segmented press-fitting, reducing single-point pressure on the mounting hole.
Multi-stage Damping Feedback: Provides different damping coefficients under small vibrations versus large impacts.
Accurate Axial Positioning: Ensures the bushing does not shift axially under dynamic loads.
Installation Stress Optimization: Segmented outer diameters make press-fitting more controllable, reducing scratches on aluminum seat holes.
Lateral Stability Improvement: The 40mm large end provides necessary lateral rigidity for cornering.
Clearance Reduction: Precision tolerance control eliminates minor joint looseness for more direct steering.
