Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X50-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X50-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 50mm 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 MACJ16X50-50S
Here the trim window matches the whole 50 mm stroke, so the effective extend length can be set anywhere from near zero to full travel - handy when final gauge is decided late in a machine build. The 16 mm bore is double-acting with cushions at both ends, giving 100.5 N push and 86.4 N pull at 0.5 MPa, or 140.7 N push at 0.7 MPa. Speeds span 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).
Construction is the classic MA recipe: a stainless round barrel roll-packed onto aluminium covers, with a 20 um hard-chrome layer over the carbon-steel 6 mm rod for long seal life. Since the magnet comes as standard equipment, CMSG / DMSG / EMSG switches bolt on from day one. In practice, size around 60 N of push at 0.5 MPa - roughly a 5 kg vertical lift kept at half capacity.

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 MACJ16X50-50S Is Used
Sample-lift stage in a lab analyser
A trimmable 50 mm raise with roughly 5 kg of vertical capacity at half rating lifts cuvette racks smoothly, and cushions settle the stage without bounce.
Height setup on a cam-follower station
Builders set final cam depth during commissioning using the 50 mm window, keeping one part number across several product heights.
Light diverter arm on a conveyor
100.5 N at 0.5 MPa nudges small parcels between lanes while the chrome-plated rod shrugs off dust and occasional wipe-downs.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X50-50S the Right Cylinder?
Nothing sits below 16 mm in this series, so upsize when forces climb: bore 20 yields 157.0 N and bore 32 reaches 402.2 N at 0.5 MPa. Remember the adjuster is an extend-side mechanical stop, not a brake - on sudden air loss the rod can sag, so interpose a valve on vertical duties. FA flange or LB foot mounting, I / Y rod knuckles, and PT (blank), G or NPT threads complete the order code.
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 MACJ16X50-50S FAQ
Expect 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, and a 20.5 kgf theoretical maximum at 1.0 MPa. Bore 16 mm, rod 6 mm, ports M5x0.8, stroke 50 mm fully trimmable, working pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
A high-precision stainless barrel is riveted together with aluminium-alloy covers and a stainless-steel block into one sealed round body. The 6 mm carbon-steel rod carries a 20 um hard-chrome plating, and the two-way piston seal stores its own grease, cutting maintenance in dusty or damp spots.
