Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X20-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X20-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 20mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X20-10S
Short 20 mm travel plus a 10 mm trim window makes the MACJ16X20-10S a natural for tiny clamp and pin-pull jobs where every millimetre counts. At 0.5 MPa the bore 16 barrel pushes 100.5 N and pulls 86.4 N; at 0.7 MPa push reaches 140.7 N, topping out at 20.5 kgf theoretical at 1.0 MPa. Keep real working force near 60 N at 0.5 MPa, which lifts about 5 kg vertically with a 2:1 margin.
The body is a stainless round tube riveted to aluminium alloy covers - no tie-rods to loosen, no paint to chip in wet areas. A 6 mm hard-chrome rod runs in a two-way seal that also stores grease, and variable cushions at both ends soften stops even on the brief 20 mm stroke. The magnet is standard, ready for CMSG, DMSG and EMSG switches; air supply is 0.15-1.0 MPa (22-145 psi) with speed 30-800 mm/s.

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 MACJ16X20-10S Is Used
Micro clamping
Clamping a 30 mm aluminium boss during deburring on a bench cell, the cushioned stop protecting the thin wall.
Stop pin setting
Retracting an alignment pin 20 mm on a gauge jig, the 10 mm window tuned per part revision.
Drawer lid push
Snapping a slider lid shut on a dispensing drawer, the stainless body coping with daily wipe-downs in a pharmacy.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X20-10S the Right Cylinder?
At the bottom of the MA range, bore 16 suits loads under roughly 60 N; move to bore 20 (157 N at 0.5 MPa) or bore 25 (245.3 N) for heavier clamps. The 10 mm stop window only shortens the extend stroke and is not a position lock - the rod will drift if air drops, so use a blocking valve where the hold matters. Mount via LB foot or FA flange, with I or Y knuckles for swinging joints. Confirm the compact envelope from the datasheet before laying out the fixture.
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 MACJ16X20-10S FAQ
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa push is 140.7 N and pull 120.9 N; maximum theoretical output at 1.0 MPa is 20.5 kgf. Air port is M5x0.8, rod thread M6x1.0 on a 6 mm rod, and the extend stroke trims within a 10 mm window.
The riveted stainless barrel plus hard-chrome plated rod resist mild corrosion, splash and washdown - a real edge in damp, food or outdoor spots where painted or plain aluminium minis pit. You also get dual adjustable cushions and the standard magnet for CMSG, DMSG and ESG sensing on a 20 mm stroke.
