Industrial Hydraulic Shock Absorbers & Deceleration Buffers (AC & AD Series)
Heavy-duty industrial hydraulic shock absorbers designed for smooth kinetic energy absorption and machine protection. Features self-compensating (AC series) and dial-adjustable (AD series) models from M8 to M36 threaded bodies. Hardened steel outer tube, micro-polished chrome piston rod, and polyurethane impact caps ensure long cycle life and silent deceleration.

| AD1410 ~ AD2525 | Adjustable Dial Damping Buffer | M14x1.5 to M25x1.5 | 10 mm ~ 25 mm | 15 Nm ~ 100 Nm (Dial 0-8) | 0.2 ~ 3.2 m/s tunable |
| HR15 ~ HR100 | Hydraulic Precision Speed Regulator | Smooth clamp body (Ø 24mm) | 15 mm ~ 100 mm | Max thrust 3000 N constant | 0.05 ~ 30 mm/s constant feed |
Standard Interchange: 100% interchangeable with SMC RB/RBC series, AirTAC ACA/ACJ series, and Enidine OEM dampers. Stop nuts and mounting bracket blocks included.
Choose a product path or send your request
Start with the moving load and installed space. Selecting a shock absorber needs energy and cycle information as well as the thread.
AirTAC ACA / ACJ reference →
Compare published absorber families; actual impact duty still requires confirmation.
AirTAC HR reference →Review the published HR function and configuration before substitution.
What helps us match your requirement
Existing code, moving mass, impact speed, cycles, available stroke, thread and mounting drawing. Unknown load data can be discussed before selection.
Missing some details? A photo, label or short description is enough to start. We clarify the requested brand and supply option before quotation.
These fields accept text and links. Send photo files by email or WhatsApp.
Add contact details and photo/file links or notes in the next step. Your request details will be carried over.
