Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-100S 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 MACJ16X125-100S
Trim the extend stroke anywhere between 25 and 125 mm once the MACJ16X125-100S is on the machine: the -100 window is set by an external stop screw, and a variable air cushion at both ends absorbs the shock of fast stops. This is a double-acting round-body mini cylinder running on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
The riveted body wraps a stainless barrel around a 6 mm hard-chrome plated rod (20 um chrome), so damp washdown corners do not chew it up the way painted minis fail. At 0.5 MPa it pushes 100.5 N, which works out to about 60 N of honest working force - plan on that, not the headline figure. A built-in magnet is standard, so CMSG, DMSG or EMSG switches clip straight on.

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 MACJ16X125-100S Is Used
Flow wrapper stop gate
Stops single confectionery bars at the discharge of a flow wrapper; 100.5 N at 0.5 MPa is far above what a 50 g bar needs, and the wide 100 mm window covers several bar widths without re-piping.
Vial indexer under a scanner
Advances sample vials one station at a time into a barcode reader on lab automation; the trimmed stop keeps the vial square to the optics while the cushion removes the rattle at the pickup point.
Capsule foil lid press
Presses foil lids onto coffee capsules on a small rotary filler; plan on about 60 N of working force, and the 6 mm rod keeps the pressing head aligned through millions of cycles.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X125-100S the Right Cylinder?
Bore 16 is the smallest in the MA series, so the only way is up: bore 20 raises the same numbers to 157.0 N push and 131.9 N pull at 0.5 MPa if 100.5 N proves light for the job. Size around 60 N of usable force and watch the 6 mm rod at 125 mm reach - offset or side loads bend thin rods, so guide the load externally where the path is long. Mount with an FA flange or LB foot; I and Y rod knuckles are also offered. Keep in mind the stop screw positions the piston only - if air is lost it drifts, so it is not a load-holding brake.
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 MACJ16X125-100S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those rise to 140.7 N and 120.9 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. For real work budget roughly 60 N at 0.5 MPa, which also means it lifts about 5 kg vertically with a 2:1 margin.
Every MA piston carries a magnet as standard equipment, so CMSG, DMSG or EMSG switches mount directly on the barrel with no special-order parts. Pair them with the variable air cushion at both ends: tune the cushion so cycles finish smoothly, and the switches catch clean, bounce-free end-of-stroke signals.
