Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 200mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75SB
The ACQJ160X200-75SB is a double-acting JIS compact cylinder featuring a 160 mm bore and a 200 mm full stroke. An external threaded stop with a lock nut limits the EXTEND end position, providing a usable extend range of 125-200 mm. The RETRACT stroke remains completely unaffected. As the big-bore compact range supports up to 300 mm stroke, this unit delivers massive force in a space-saving riveted body. The -S magnet enables position sensing with reed or solid-state switches, and the -B male rod end (M36x1.5) couples directly to your load.
Because the adjuster changes stroke length only, the piston area remains the same, meaning the force is identical to a standard ACQ of this bore. At 0.5 MPa, it generates 10053.1 N of push force and 9424.8 N of pull force. Fixed NBR elastomer bumpers at each end decelerate the rod near stroke limits, handling speeds of 30-500 mm/s without requiring adjustable air cushions.

| Rod thread | M24×3.0 (F) / M36×1.5 (B) |
Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75SB Is Used
Heavy Press Tonnage Calibration
Dial in the exact 125 to 200 mm extend reach during heavy press setup, allowing rapid tonnage adjustments without machining custom spacers.
Large Weldment Positioning
Shift the end stop to accommodate varying steel weldment lengths on the fly, ensuring precise clamping without swapping pneumatic hardware.
Bending Machine Trial Stops
Find the perfect bend angle by trialing different extend positions on a thick-plate bending machine before locking the nut for production.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75SB the Right Cylinder?
For lighter duties, stepping down to a bore 140 yields 7696.9 N push at 0.5 MPa, while no larger bore exists in this compact family. If the exact 200 mm extend position never varies, a fixed-stroke ACQ cylinder is simpler. When ordering, confirm the 160 mm bore, 200 mm full stroke, 75 mm window, the -S magnet, and the -B male rod thread. The PT3/8 port and M36x2.0 adjuster thread are fixed by the bore.

- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-75SB FAQ
It provides 10053.1 N push and 9424.8 N pull at 0.5 MPa, 14074.3 N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The full stroke is 200 mm with a 75 mm window, yielding a usable extend range of 125-200 mm.
No, the adjuster changes stroke length only, so force is identical to a standard ACQ. The fixed NBR bumper decelerates the rod near stroke end, but a plain ACQ does not hold its load on air loss; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
