Cabin Buffer installed on truck cabin, made from elastic component typically made of high-elasticity polyurethane. It has the same functions of Jounce Bumper (also known as Bump Stop, Bump Rubber, Rubber Buffer or Strut Bumper) to provide progressive auxiliary stiffness at the end of compression stroke, used on heavy-duty trucks such as Scania,MAN, DAF,Renault,Mercedes-Benz,BRG,Volvo.etc

Functions

· Provides auxiliary stiffness at end of compression stroke, limits travel, prevents bottoming out.

· Absorbs impact energy, reduces noise and load from metal-to-metal contact.

· Improves ride comfort under large impacts.

Temperature Range -40°C to +90°C (meets standard passenger car requirements; material can be adjusted for special conditions).

Service Life Design life ≥80,000 km or 2 years under normal use – no cracking, excessive permanent deformation, or stiffness loss.

Warranty & Quality

· Quality Standard: IATF 16949. Inspects static stiffness curve, compression set, hardness, appearance.

· Warranty: Typically 1–2 years or 50,000–100,000 km.
