Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 200mm stroke, 1/4" 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 MACJ63X200-40S
Need to fine-tune extend length after installation? The MACJ63X200-40S lets you trim up to 40 mm off its 200 mm stroke with an external stop screw, while the 63 mm stainless round barrel commands 1557.9 N of push at 0.5 MPa. Plan on roughly 935 N of usable force, enough to lift about 79 kg vertically with a 2:1 safety margin.
A variable air cushion at each end absorbs deceleration shock, so you can run 30-800 mm/s against heavier tooling without hammering the aluminium covers. The 16 mm hard-chrome rod resists corrosion in wet, washdown-prone cells, and the piston magnet fitted as standard accepts CMSG / DMSG / EMSG switches out of the box. Operating range is 0.15-1.0 MPa (22-145 psi).

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MACJ63X200-40S Is Used
Press-shop die lifter
The 40 mm window aligns a die-changing lift plate precisely; about 79 kg of vertical lift capacity with margin suits loaded change-over fixtures.
Bottling-line gate diverter
Trims gate throw by up to 40 mm after install, and the stainless barrel with hard-chrome rod handles the wet, sticky conditions around rinse stations.
Gripper home-position check
The built-in magnet and an EMSG switch verify the gripper arm reached the adjusted home stop before the robot cycle is allowed to start.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-40S the Right Cylinder?
Step through the sizing: a 50 mm cylinder manages 981.3 N of push at 0.5 MPa, so any job above roughly 900 N of working force points to this 63 mm body, which also reaches 2181 N at 0.7 MPa. Remember the stop screw sets extend length only - it will not lock the rod against drift when air pressure is lost.
Choose FA flange or LB foot mounting and pair the I or Y knuckle with your linkage. Keep rod side-loading low across the 200 mm travel; an external linear guide preserves seal life on longer strokes.
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 MACJ63X200-40S FAQ
Push 1557.9 N and pull 1457.4 N at 0.5 MPa; push 2181 N and pull 2040.3 N at 0.7 MPa; 317.7 kgf theoretical maximum at 1.0 MPa. Double-acting, 63 mm bore, 200 mm stroke with a 40 mm adjustable extend window and variable air cushions at both ends.
No extra cost or special order - every MA-series piston carries a built-in magnet as standard, so CMSG, DMSG and EMSG switches mount directly on the stainless barrel and read position of the trimmed extend stop.
