Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 40mm 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 MACJ16X40-40S
Stroke tuning across the entire travel sets this version apart: with a 40 mm window matching its 40 mm stroke, the external stop screw can hold the extend stroke anywhere from full length down to a near-zero nip. The variable air cushion at both ends absorbs deceleration shock, so a faster 30-800 mm/s cycle stays kind to the covers. Double-acting, the 16 mm bore delivers 100.5 N push and 86.4 N pull at 0.5 MPa.
Damp and rinse-down areas are its natural home: the rolled stainless barrel and hard-chrome carbon-steel rod resist the corrosion that flakes painted minis in a bottling hall. Halve the push figure and you get roughly 5 kg of vertical lift with a 2:1 margin - handy when matching vial or connector weights. Sensing is covered from day one thanks to the piston magnet fitted as standard, which accepts CMSG / DMSG / EMSG reed and electronic switches across a 0.15-1.0 MPa (22-145 psi) supply.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-40S Is Used
Connector pin press-fit
Seats USB pins into housings on a small assembly press; roughly 5 kg of vertical lift with margin matches typical connector weights, and the dual cushioning protects the fixture.
Micro-part divertor
Pushes M3 fasteners off a bowl-feeder track into a reject chute, with the full 40 mm window letting maintenance retune the divert depth after track changes.
CNC door latch actuator
Latches the guard door of a compact router; 100.5 N of push is comfortable for a light aluminium door, and the chrome-plated rod shrugs off coolant mist.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X40-40S the Right Cylinder?
Compare before committing: a 20 mm MACJ20 bore offers 157 N at 0.5 MPa against this cylinder's 100.5 N, while there is nothing smaller in the series, so 16 mm is already the compact floor. Remember the stop screw trims the extend stroke but will not lock the piston mid-travel - under air loss the rod still moves. FA flange or LB foot mounting plus an I / Y rod knuckle cover most fixtures, and the built-in magnet pairs with CMSG / DMSG / EMSG switches for end-of-travel confirmation.
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 MACJ16X40-40S FAQ
Push at 0.5 MPa is 100.5 N and pull 86.4 N; at 0.7 MPa it is 140.7 N push and 120.9 N pull, with a 20.5 kgf theoretical maximum at 1.0 MPa. The 40 mm adjustment window covers the entire 40 mm stroke, the air cushion is variable at both ends, and speed range is 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air.
The rolled stainless round barrel and hard-chrome plated rod shrug off the condensation and rinse mist found in food and beverage plants, where painted minis blister. The covers are rolled directly onto the tube, so the joint stays tight through washdown cycles and the 6 mm rod keeps running true.
