AC / AD / ACD / ACA / ACJ Series Hydraulic Shock Absorber

SOLH AC / AD / ACD / ACA / ACJ Series Hydraulic Shock Absorber | Pneumatic Dashpot

Brand: SOLH by Richge Technology | Airtac Equivalent Hydraulic Shock Absorber

1. Product Overview

     SOLH AC / AD / ACD / ACA / ACJ series hydraulic shock absorbers are mainstream pneumatic buffer dampers, fully compatible with Airtac model coding, mounting dimensions and performance parameters. Direct drop-in replacement for imported buffers, with competitive cost and shorter lead time for volume machine cost reduction.

     This family covers fixed damping, adjustable damping, bidirectional buffer and auto-compensation types, widely used for cylinder end cushioning, robotic transfer mechanism, rotary actuator, automation fixture and high-speed handling equipment to absorb kinetic impact and reduce vibration, noise and mechanical collision damage.

5. Model Interpretation Examples

     • AC1416-1N: Fixed multi-orifice, M14 thread, 16mm stroke, high-speed light load, without buffer cap

     • AD2020-2: Adjustable type, M20 thread, 20mm stroke, medium speed medium load, standard buffer cap included

     • ACD1630: Bidirectional shock absorber, M16 thread, 30mm stroke (no speed & cap suffix)

     • ACA1412-2: Auto-compensation non-adjustable, M14 thread, 12mm stroke, medium speed medium load, plastic impact cap

     • ACJ2020-F: Adjustable auto-compensation, M20 thread, 20mm stroke, iron heavy-duty impact cap (no speed code)

6. Selection & Operation Guidelines

     1. Select series first: Confirm whether damping adjustment and bidirectional buffer are required according to working complexity

     2. Match thread and stroke: Thread size must fit mounting hole; buffer stroke must be shorter than total mechanism travel to avoid hard bottom collision

     3. Speed & load matching: ACA models select grade 1/2/3 by speed and load; AC/AD/ACD are pre-engineered for rated condition

     4. Impact cap selection: Plastic cap for general use; iron cap for heavy load / high frequency; N type no-cap when space is limited

     5. Installation note: Apply small amount of anaerobic thread locker, PTFE tape is forbidden. Manually test after installation to ensure smooth piston movement without sticking

7. Replacement Note

     SOLH AC/AD/ACD/ACA/ACJ shock absorbers adopt identical naming convention, mounting dimensions and performance curve as Airtac. Direct drop-in replacement for imported dampers, with lower cost and faster lead time, ideal for mass equipment cost-down projects.
