Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-100SB
The AirTAC Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-100SB 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 ACQJ160X200-100SB
The ACQJ160X200-100SB is a double-acting JIS compact cylinder from AirTAC's big-bore range, 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 extension range of 100 to 200 mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area stays constant, the output force is identical to a standard ACQ of this size, yielding 10053.1 N push and 9424.8 N pull at 0.5 MPa.
This variant includes a male piston rod end (M36x1.5) for direct load coupling and a built-in piston magnet (-S) for use with reed or solid-state switches. Instead of an adjustable air cushion, it relies on a fixed NBR elastomer bumper at each end to decelerate the motion near the stroke limits. Operating pressure spans 0.15 to 1.0 MPa, and the PT3/8 port manages the pneumatic supply for the 40 mm rod.

| 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 ACQJ160X200-100SB Is Used
Heavy Press Tonnage Calibration
Dial in the exact extend end position during heavy press setup or product-changeover, adjusting the 100 to 200 mm range on the machine without machining new spacers.
Large Fixture Clamping
Adapt clamping depth for varying large-part geometries in fabrication cells, relying on the 2050 kgf max push force to secure heavy workpieces firmly.
Bending Machine Trial Stops
Establish precise trial end positions for sheet metal bending, using the external M36x2.0 adjuster thread to fine-tune the stroke limit while the fixed elastomer bumper absorbs end-impact.
Is the Airtac ACQJ125~160 Adjustable Compact Cylinder ACQJ160X200-100SB the Right Cylinder?
When sizing this big-bore actuator, consider the neighbouring bores: a 140 mm unit provides 7696.9 N push at 0.5 MPa, while no larger standard ACQJ bore exists in the compact range, making this 160 mm model the maximum force option at 10053.1 N push (14074.3 N at 0.7 MPa). If your application never requires altering the extend end position, a fixed-stroke ACQ cylinder provides the same power in a simpler setup. To order correctly, confirm the 160 mm bore, 200 mm full stroke, 100 mm adjustment window, the -S magnet for sensing, and the -B male 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 ACQJ160X200-100SB FAQ
It delivers 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 100 mm adjustment window, giving a usable extend range of 100 to 200 mm.
The external threaded stop with a lock nut limits the extension distance without altering the piston area, so the force remains identical to a standard ACQ. The retract stroke is unaffected, and the fixed NBR elastomer bumper decelerates motion near the ends. A plain ACQ-type does not hold its load on air loss, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.
