Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-20S
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-20S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø160mm bore and 100mm 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 ACQJ160X100-20S
The ACQJ160X100-20S is a double-acting, single-rod JIS compact cylinder featuring a 160mm bore and a 100mm full stroke. An external threaded stop with a lock nut limits the extend end position, providing a usable extend range of 80 to 100mm. The retract stroke remains completely unaffected by this adjustment mechanism. As the big-bore variant in the ACQJ series, it supports up to 300mm strokes while retaining a space-saving riveted body design.
Because the internal piston area is unchanged, the output force is identical to a standard ACQ of this size. You generate 10053.1N of push force and 9424.8N of pull force at 0.5 MPa, with a maximum push capacity of 2050 kgf at 1.0 MPa. The -S suffix indicates a built-in piston magnet compatible with both reed and solid-state electronic switches for precise position sensing. Fixed NBR elastomer bumpers at each end decelerate the load, though external shock absorbers are recommended for high-energy impacts.

| 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 ACQJ160X100-20S Is Used
Heavy Press Tuning
Dial in the exact 80 to 100mm extend position on a large metal-forming press during setup, allowing quick accommodation of varying material thicknesses without machining new stop collars.
Large Fixture Changeover
Adapt heavy-duty clamping fixtures on automated welding lines rapidly by turning the external M36x2.0 adjuster to meet new part dimensions, reducing product changeover downtime.
Prototype End Stops
Establish trial end positions on a new stamping machine by fine-tuning the extend stroke in 1mm increments, locking the nut once the optimal working distance is found.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X100-20S the Right Cylinder?
When sizing this big-bore 160mm unit, consider the adjacent bore options for your force requirements. Stepping down to a 140mm bore yields 7696.9N push force at 0.5 MPa, while stepping up to the 160mm bore provides 10053.1N at the same pressure. If your application requires a fixed extend position and no on-the-fly adjustments are necessary, a standard ACQ series cylinder will suffice. To order this adjustable model correctly, confirm the 160mm bore, 100mm full stroke, 20mm adjustment window, the -S magnet option, and the default female rod-end thread (M24x3.0). The standard port size is PT3/8.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ 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 ACQJ160X100-20S FAQ
The usable extend range is 80 to 100mm (a 100mm full stroke minus the 20mm adjustment window). The output force equals a standard ACQ of the same bore: 10053.1N push and 9424.8N pull at 0.5 MPa, 14074.3N push at 0.7 MPa, and a maximum push of 2050 kgf at 1.0 MPa. The adjustment mechanism alters stroke length only, not the piston area or force.
An external M36x2.0 threaded stop with a lock nut limits the extend stroke, allowing on-machine tuning without replacing parts. The retract stroke remains fixed. Fixed NBR elastomer bumpers at both ends decelerate the load; they are not adjustable air cushions. Note that a plain ACQ-type cylinder does not hold its load on air loss, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.
