Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 160mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-30S
Double acting with a variable air cushion at each end, the MACJ40X160-30S pairs a 40 mm bore with an extend stroke that can be trimmed on site by up to 30 mm inside the ordered 160 mm. At 0.5 MPa it pushes 628 N and pulls 528 N, rising to 880 N at 0.7 MPa; treat roughly 377 N as the practical working force so the cylinder keeps margin in hand.
The stainless round barrel and hard-chrome plated 16 mm rod shrug off washdown and damp shop air better than painted mini bodies, and the riveted aluminium covers keep the package sealed. Since the magnet ships built in, CMSG, DMSG or EMSG switches clamp straight onto the barrel without a special-order piston.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-30S Is Used
Conveyor stopper gate
Set the gate drop point precisely by trimming the extend stroke within the 30 mm window; the dual cushions keep the stopper from hammering even at 800 mm/s cycle tops.
Bracket pick-and-place
With about 377 N of dependable working push, the cylinder seats aluminum housings into a fixture on an assembly cell while the built-in magnet signals home to a CMSG switch.
Terminal crimp assist
A packaging-line crimp station uses the 130-160 mm trimmed range to match different connector heights without swapping shims or re-drilling mounts.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-30S the Right Cylinder?
If 628 N at 0.5 MPa is more than the job needs, the 32 mm bore delivers 402 N; when loads climb, step up to the 50 mm bore at 981 N. The trim screw shortens the extend stroke only - it is a mechanical end stop, not a mid-stroke brake, so the rod can still drift if air is lost. Choose FA flange or LB foot mounting, add an I or Y rod knuckle where the load pivots, and keep side loads off the 16 mm rod over the full 160 mm travel.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-30S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa the figures rise to 880 N push and 739 N pull. The theoretical ceiling is 128.1 kgf at 1.0 MPa. The port is 1/8 in, the rod thread is M12x1.25, and the extend stroke runs 130-160 mm after trimming.
Yes - the stop screw shortens the stroke by any amount up to 30 mm, down to a 130 mm minimum, with no disassembly. The rod remains free to move when air pressure drops, so do not rely on the adjuster to hold a load; use valving for that.
