Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X75-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X75-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 75mm 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 MACJ16X75-20S
A mid-length 20 mm window gives this 16 mm bore MACJ room for on-site stroke trimming - enough range to retune the 75 mm extend position when a product size or tooling changes. Air works on both faces of the piston, and the variable cushion at each end lets you run 30-800 mm/s without hammering the covers.
The round stainless barrel is rolled onto aluminium covers with a stainless block, sealing out moisture that defeats painted mini cylinders. Hard-chrome on the 6 mm carbon-steel rod adds further corrosion resistance. Magnet is a standard inclusion, so a CMSG or DMSG switch snaps on for position feedback. In practice, size the task to roughly 60 N of push at 0.5 MPa rather than the full 100.5 N - about 5 kg of vertical lifting with margin.

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 MACJ16X75-20S Is Used
Blister-line reject pusher
Tipping faulty blister packs off a pharma conveyor, with cushioned landings at both ends of the 75 mm travel.
Chute gate control
Diverting plastic caps between collection chutes on a bottling aux line; the 20 mm window absorbs product-change tweaks.
Sample presenter
Sliding a vial into an analytical sampler position, confirmed by a magnet-triggered CMSG switch on the barrel.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X75-20S the Right Cylinder?
Between the 20 mm bore (157.0 N push at 0.5 MPa) and this 16 mm unit (100.5 N), the crossover sits near a 6 kg load at moderate pressure; go up a bore if your mass is close to the limit. Bore 16 tops out at a 300 mm standard stroke, so 75 mm is fully standard. Mount via FA flange or LB foot, or hang an I or Y knuckle on the rod thread. Note the stop screw fixes the extend end position only - it is not a holding brake, and the rod will move if supply pressure falls.
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 MACJ16X75-20S FAQ
At 0.5 MPa: 100.5 N push, 86.4 N pull. At 0.7 MPa: 140.7 N push, 120.9 N pull. Maximum theoretical force is 20.5 kgf at 1.0 MPa. The 16 mm bore uses a 6 mm rod with M6x1.0 male thread and an M5x0.8 port, running on 0.15-1.0 MPa (22-145 psi) filtered air.
The rolled stainless round barrel plus hard-chrome plated rod shrug off condensation and light washdown where painted minis corrode. Combined with the standard built-in magnet for CMSG, DMSG or EMSG switches, it suits wet or humid stations without special ordering.
