Rubber buffers
Sub-Categories & Damping Solutions
Hangzhou Powertrans supplies a comprehensive range of industrial anti-vibration elements engineered to mitigate mechanical noise, shocks, and structural wear. Select your specific configuration based on your structural load and geometry requirements:
-
Cylindrical Rubber Buffers (Types 1 – 5): The industry standard for general multi-directional vibration damping. Available in male/male, male/female, female/female, and single-stud end-stop configurations.
-
Conical & Parabolic Dampers: Engineered for progressive impact absorption. Designed to effectively decelerate heavy loads and absorb multi-angle shocks.
-
Hourglass (Waisted) Buffers: Specially designed for compact spaces and height-constrained installations requiring high lateral stability.
-
Bell-Type Machinery Mounts: Feature specialized heavy-duty damping properties with integrated pull-out protection for critical engine and motor isolation.
-
Vibration-Damping Levelling Feet: Built for heavy-load equipment requiring precision leveling, featuring galvanized or stainless steel base plates coupled with high-durability elastomer compounding.
