Helpful for Model Matching:
- Complete ACA/ACJ code or installed label/drawing
- Body thread,stroke,cap and installed length
- ACA speed1/2/3 or ACJ adjustment
- Impact energy,mass,speed and cycles/hour
- Thrust/gravity energy,stop clearance,temperature
- Mounting accessory,quantity and destination
- Choose self-compensating ACA or adjustableACJ
- Match body/stroke,cap,length and mounting clearance
- Confirm impact energy/hourly capacity,mass,speed and cycles
- Use mechanical stop and verified accessory pairing
Catalogue Technical Specifications
| Family boundary | ACA self-compensating hydraulic impact shock absorber;ACJ manually adjustable hydraulic impact shock absorber. HR is an adjustable hydraulic speed controller, not this shock-absorber family. Body/stroke/speed/cap and mounting accessories remain matching fields, not separate series pages. |
| Ordering / thread | ACA[body][stroke]-[1/2/3][optionalN/F];ACJ[body][stroke][optionalN/F] with no speed-code field. Body male thread M8/M10/M12×1.0 and M14/M16/M20/M25/M27/M33/M36/M42×1.5;only published model pairs allowed. |
| ACA model pairs | 08×06;10×07;12×10/15;14×12/16/20;16×16/20/25;20×20/25/30/40;25×25/50;27×25/50;33×25/50;36×25/50 mm body/stroke code;22 published base models. ACA2725 is real;ACA2575 is not in this catalogue. |
| ACJ model pairs | 10×07;12×10;14×12;20×20;25×25/50;27×25/50;33×25/50;36×25/50;42×25/50/75 mm body/stroke code;15 published base models. No ACJ08/16 or ACJ1215. |
| ACA impact speed | 1 high speed/light load,2 medium speed/medium load,3 low speed/heavy load. Published maxima4/2/1m/s respectively;energy-speed curves define actual allowable region. Source recommends using20–80% of maximum absorbed energy. The 4m/s maximum does not apply to every ACA setting. |
| Cap options | Blank=plastic cap. ACA08–16 and ACJ10–14:blank/N no cap only. ACA/ACJ20–27:blank/F iron/N no cap. ACA33/36 and ACJ33/36/42:blank/F iron only,no publishedN. Cap changes installed end geometry;confirm source drawing. |
| Energy / effective mass | Per-impact energy J=N·m;hourly capacity J/h=N·m/h;max effective mass kg;impact speed m/s. All criteria and energy-speed curve must be satisfied together. Effective mass is not guaranteed payload. Include driven/propelling energy,not only kinetic energy;cycles/hour affects hourly heat capacity. |
| ACJ adjustment | Source wording scale0–9(8),factory6(4) is ambiguous;confirm scale and factory setting for the actual unit,do not assume universal4. Scale0 softest,9 hardest. Early rebound:soften toward0;end-of-stroke rebound:harden toward9. ACA rebound may require another speed type,not adjustment knob. Selection remains application-specific. |
| Installation / stop | Avoid lateral load;eccentric angle within3°.Securely lock body;do not use absorber as mechanical travel stop. Source says stop piston1mm before stroke end using positioning/precise adjustment stop. Multiple absorbers must act synchronously;moment force must remain within catalogue range. |
| Operating / handling | Published operating temperature−5 to70°C. Do not paint,weld or apply corrosive cleaning to body/rod. Scratched piston rod and external water/oil may reduce service life. No force increase or safety guarantee inferred from sealed body/QPQ claims. |
| Mounting torque | Maximum assembly torque N·m:ACA0806/M8=2;M10=3.5;M12=8;M14=11;M16=15;M20=24;M25=40;M27=63. Model33/36/42 not included in this torque table and require confirmation. ACA0806 female-thread prep note bottom diameter7.1(+0.1/0)mm;do not apply to other models. |
| Accessories / compatibility | F-ACA[size]LM stop collar,not shock absorber model or iron-capF. LM published08/10/12/14/16/20/25/27/33/36;FA flange36/42 only in source table. F-ACA08LM onlyACA0806;42FA onlyACJ4225/4250/4275. Shared F-ACA accessory prefix can fit ACJ by table;not blanket interchangeability. |
| Selection data to submit | Installed code/label/drawing;moving/effective mass;impact speed and direction;additional cylinder thrust/gravity/rotation energy;cycles per hour;available stroke/clearance;cap,stop collar/flange,temperature;quantity and destination. Catalogue no-load cylinder example at0.6MPa,size40/stroke12 gives9.04J;loaded example twice that is conditional,not universal doubling rule. |
| Representative ACA ratings | ACA2020:20mm stroke,60J per impact,50000J/h;speed1/2/3 max effective mass240/660/960kg and max speed4/2/1m/s. ACA2725:25mm,140J,85000J/h,560/1550/2240kg. ACA3650:50mm,350J,150000J/h,1400/2500/5600kg. The published maximum effective mass for ACA3650 speed type 2 is 2500kg; confirm the selected speed type against the actual application. |

Quick check
Can a matching model code confirm my load or let me substitute ACA and ACJ?
A matching code confirms published model fields only. ACA uses self-compensating speed types1/2/3;ACJ uses adjustable damping. Check per-impact and hourly energy,effective mass,speed,cap and mounting together. Send actual operating cycle and installed drawing;dimensions alone do not establish interchangeability.
