Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 300mm 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 MACJ16X300-30S
With a 300 mm stroke on a 6 mm hard-chrome plated rod, the MACJ16X300-30S reaches across wide nests while staying light. Its rolling-packed body - a stainless barrel with riveted aluminium covers and a stainless block - seals reliably and tolerates the damp, washed-down corners where painted minis blister.
Thrust at 0.5 MPa is 100.5 N extending and 86.4 N retracting (140.7 N at 0.7 MPa), enough for about 10 kg of vertical lift at full pressure, so budget around 5 kg of payload for a 2:1 margin. The extend stroke trims inside a 30 mm window, and the variable cushion at each end absorbs the landing, keeping the 30-800 mm/s speed band usable on snappy cycles.

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 MACJ16X300-30S Is Used
Bottle rejector
Sweeping underfilled bottles off a beverage line into a reject chute, using the 30 mm window to match lane pitch without re-plumbing.
Vending flap drive
Opening product flaps in compact vending cabinets where a 300 mm reach and a 10 kg vertical-lift class cover the mechanism.
Dosing head trim
Fine-tuning a small dosing head's stroke on a filling skid in place, no shims or disassembly needed.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X300-30S the Right Cylinder?
Compare before ordering: bore 16 pushes 100.5 N at 0.5 MPa, bore 20 manages 157.0 N and bore 25 reaches 245.3 N - pick the larger bores when friction in your mechanism eats margin. The stop screw here trims extend stroke within 30 mm; remember it limits travel but will not arrest a falling or drifting load once supply pressure drops.
Choose FA or LB mounting to suit the frame and fit I or Y rod knuckles for linkage work. Long 300 mm strokes amplify any misalignment, so guide the load separately and protect the 6 mm rod from bending; the built-in magnet plus a CMSG or DMSG switch covers end-position feedback.
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 MACJ16X300-30S FAQ
Push 100.5 N and pull 86.4 N at 0.5 MPa; push 140.7 N and pull 120.9 N at 0.7 MPa; roughly 20.5 kgf theoretical at 1.0 MPa. Operating band is 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, fluid air filtered to 40 um, piped via M5x0.8.
A high-precision stainless-steel barrel, a carbon-steel piston rod hard-chrome plated to 20 um, and aluminium-alloy covers rolled onto the tube together with a stainless block. The round riveted body tolerates splash and mild corrosives far better than painted minis, and it is AirTAC's own MA format rather than a standardized profile.
