Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X200-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X200-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 200mm stroke, 1/8" 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 MACJ40X200-75S
Trim the extend stroke of this 200 mm AirTAC MACJ cylinder anywhere within a 75 mm window using the built-in adjuster, with a variable air cushion at each end to absorb the landing. The 40 mm bore is a mid-force workhorse: 628.3 N push and 527.8 N pull at 0.5 MPa, climbing to 879.6 N at 0.7 MPa. Derate to roughly 377 N of usable push and it will lift about 32 kg against gravity with a 2:1 margin.
Construction is the classic riveted MA round body - a stainless steel tube rolled onto aluminium covers with a 16 mm hard-chrome carbon-steel rod that tolerates humid and lightly corrosive plant air. Every unit carries a standard magnet for CMSG, DMSG and EMSG switches, so sensing needs no options.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MACJ40X200-75S Is Used
Robot cell part-present check
Pushes finished brackets onto an inspection nest; the 75 mm trim absorbs fixture tolerance and the magnet signal clears the robot to pick.
Glue head depth setting
Sets bead start height on a carton gluer by trimming stroke within 75 mm - retune per carton size without swapping the cylinder.
Accumulation stop arm
Raises a stop blade under moving totes; 527.8 N of pull keeps the arm down against line back-pressure while cushions soften every cycle.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X200-75S the Right Cylinder?
Compared with the 32 mm MA cylinder (402.2 N at 0.5 MPa) this bore has around 55 percent more muscle, while the 50 mm size (981.3 N) serves heavier clamps. If the duty is holding rather than stroking, remember the adjuster is a stroke end stop - with air lost the piston coasts, so never count on it as a brake. FA flange and LB foot brackets, plus I and Y knuckles, cover most fixturing, and the 75 mm window suits feed tracks whose stop position gets retuned often.
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 MACJ40X200-75S FAQ
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa expect 879.6 N push and 738.9 N pull, and 128.1 kgf theoretical at 1.0 MPa. Stroke adjustment covers 75 mm, cushioning is variable at both ends, and the operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
The rolled stainless tube and 20 um hard-chrome plated rod resist rust from washdown, condensation and outdoor exposure where paint chips and aluminium pits. Covers stay aluminium for light weight, and the sealed rolling joint keeps grease in the two-way piston seal through long dry runs.
