Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 250mm 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 MACJ16X250-50S
AirTAC's MACJ16X250-50S gives machine builders a 250 mm double-acting stroke that can be wound down to 200 mm on site, a 50 mm window handled by the external adjuster rather than a new cylinder order. A variable air cushion at each end tames end-of-stroke shock, and the piston magnet is included as standard for CMSG / DMSG / ESG switching.
The rolled stainless tube and hard-chrome plated rod tolerate washdown and outdoor splash far better than painted minis, while the grease-storing piston seal keeps friction low over long travel. At 0.5 MPa the 100.5 N push translates to about 60 N of real work, lifting roughly 5 kg vertically, with speeds of 30-800 mm/s on a 0.15-1.0 MPa (22-145 psi) supply.

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 MACJ16X250-50S Is Used
Damper blade actuation
Swings a light HVAC damper blade between open and closed, cushioning removing the clang at each end of travel.
Tote indexing
Advances one plastic tote per cycle on a gravity-rack picking lane, with 30-800 mm/s speed matched to the sorter pitch.
Label press head
Presses self-adhesive labels onto round cosmetic jars at a benchtop station, the 200-250 mm setting matching jar height.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X250-50S the Right Cylinder?
For jobs needing more muscle, the 20 mm bore pushes 157.0 N and the 25 mm bore 245.3 N at 0.5 MPa in the same MA family; if those figures look oversized, this 16 mm bore is the economical pick. Remember the adjuster fixes only the extend end - it is not a holding device, so the rod can creep if supply pressure drops. Choose FA or LB mounting, add I / Y knuckles for swivelling loads, and keep side loads light across the 250 mm stroke to spare 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 MACJ16X250-50S FAQ
Use 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N push at 0.7 MPa; the theoretical maximum is 20.5 kgf at 1.0 MPa. For margin, plan real work around 60 N at 0.5 MPa.
No. Every MA-series cylinder leaves the factory with the piston magnet fitted as standard, so AirTAC CMSG, DMSG or EMSG switches snap onto the stainless barrel for end-of-stroke signaling with no special-order piston.
