Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 75mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50SB
The AirTAC ACQJ80X75-50SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that restricts the EXTEND end position. The full stroke is 75 mm, and the 50 mm adjustment window allows you to set the usable extend range from 25 mm up to 75 mm directly on the machine. The RETRACT stroke remains unaffected by this mechanism.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 2513.2 N push at 0.5 MPa. The cylinder features a 25 mm piston rod, a PT3/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration. The -S magnet enables position sensing with reed or electronic solid-state switches, while the -B male rod end (M22x1.5) couples directly to your load.

| Rod thread | M16×2.0 (F) / M22×1.5 (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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50SB Is Used
Machining Fixture Stops
Dial in the exact extend position within the 25 to 75 mm range during part-changeovers on CNC loading stations without machining new stop collars.
Variable Carton Sealing
Adapt the pressing stroke on the fly for different package heights, using the external M20x1.5 adjuster to maintain consistent sealing force.
Press Trial Positions
Safely test intermediate end positions on a metal-forming press before finalizing the mechanical layout, relying on the fixed elastomer bumper for impact absorption.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50SB the Right Cylinder?
This 80 mm bore provides 2513.2 N push and 2267.8 N pull at 0.5 MPa. If you need slightly less force, the 63 mm bore yields 1558.6 N push, or for heavier demands, the 100 mm bore offers 3927.0 N push. A fixed-stroke ACQ is sufficient if your extend endpoint never varies, but this adjustable model is ideal when setups change. Confirm the 75 mm full stroke, the 50 mm window, the -S magnet for sensors, and the -B male M22x1.5 rod thread when ordering.
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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-50SB FAQ
The usable extend range is 25-75 mm (75 mm full stroke minus the 50 mm window). The force equals a standard ACQ: push is 2513.2 N and pull is 2267.8 N at 0.5 MPa, push is 3518.5 N at 0.7 MPa, and max push is 513 kgf at 1.0 MPa.
The external M20x1.5 threaded stop with lock nut limits only the extend length, leaving retract intact. Force is unchanged because the piston area is the same. The cylinder uses fixed elastomer bumpers, not an air cushion, and will drift on air loss, so use an external rod lock for fail-safe holding.
