Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 125mm stroke, M5×0.8 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 MACJ16X125-50S
Fifty millimetres of on-site stroke trim makes the MACJ16X125-50S a fit-everything spare for fixture benches. Double-acting air drives the rod both ways, and a variable cushion at each end softens arrival at the adjusted stop.
Bore 16 delivers 100.5 N at 0.5 MPa (140.7 N at 0.7 MPa), enough to lift roughly 5 kg vertically with a 2:1 margin. The rolled stainless barrel resists corrosion in humid shops far better than coated minis, and the grease-retaining two-way piston seal keeps friction low over millions of cycles. A magnet is fitted as standard for CMSG / DMSG / EMSG sensing.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MACJ16X125-50S Is Used
Lab automation positioning
Dial the 50 mm window to index sample trays precisely, with 100.5 N of thrust available for light clamping.
Small-part ejection
Eject finished components off a bench fixture; the variable cushion lets you run fast without parts bouncing.
Fixture clamping jig
Standard magnet plus a CMSG switch confirms the clamp is fully home before the next station cycles.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-50S the Right Cylinder?
Keep this 16 mm bore for loads in the 60 N range; take bore 20 at 157 N or bore 25 at 245.3 N when the job grows. Remember the adjuster only trims the extend stroke and does not lock the piston against drift when air drops. Choose FA flange or LB foot mounting, add an I or Y knuckle for pivoting links, and support any side load over the 125 mm stroke to protect the 6 mm rod.
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 MACJ16X125-50S FAQ
At 0.5 MPa the MACJ16X125-50S pushes 100.5 N and pulls 86.4 N; at 0.7 MPa it reaches 140.7 N push and 120.9 N pull, peaking at 20.5 kgf theoretical. Air supply is 0.15-1.0 MPa (22-145 psi).
The barrel is stainless steel with the covers riveted on, and the carbon-steel rod carries a 20 um hard-chrome plate. That combination handles splash, humidity and light washdown that would rust painted mini cylinders.
