Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-20S 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 MACJ63X200-20S
Need 200 mm of reach with room to fine-tune it? The MACJ63X200-20S couples a 63 mm bore to a 200 mm stroke with a 20 mm adjustable extend window, so end position can be reset on the machine without swapping cylinders. It is double-acting, pushes 1558 N at 0.5 MPa and carries a variable cushion at each end of the stainless round body.
The numbers matter at this force class: 1558 N of push equals about 158 kg of vertical lifting at 0.5 MPa, or around 79 kg once you take a 2:1 safety margin, so weigh gates, lifts and sleds against that figure before committing. The riveted stainless construction with a hard-chrome plated rod is what keeps it running in wet bays and outdoor lines where painted-steel minis corrode.

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 MACJ63X200-20S Is Used
Pallet-gate lift
Raises a counterweighted safety gate on a palletising cell; about 79 kg of practical vertical capacity covers a steel gate with margin.
Sack push-off
Pushes filled 25 kg sacks off a filling station onto a takeaway belt; 1558 N of push at 0.5 MPa clears a stuck sack without stalling.
Saw advance slide
Feeds a crosscut saw into steel tube stock over 200 mm; the 20 mm window sets the final depth of cut at each product changeover.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X200-20S the Right Cylinder?
A bore 32 cylinder offers 402 N of push at 0.5 MPa, barely a quarter of this barrel, so anything lifting close to 79 kg should stay at 63 mm. If the job needs force from both rod ends, look at the double-rod MACD63; if the stroke is fixed forever, the MAC63 without the adjuster saves a little. Mount via FA flange or LB foot, fit I or Y knuckles to linkages, and note the stop screw is a position trim, not a load lock if air pressure drops.
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 MACJ63X200-20S FAQ
Measured outputs are 1558 N push and 1457 N pull at 0.5 MPa, climbing to 2181 N and 2040 N at 0.7 MPa. Theoretical maximum at 1.0 MPa is 317.7 kgf. For dependable sizing, count on roughly 935 N of working push at standard supply pressure.
Yes - the magnet is standard on every MA cylinder, so CMSG, DMSG or EMSG switches mount directly on the barrel to signal the trimmed end position, with no special piston and no extra charge.
