Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X125-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X125-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 125mm 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 MACJ63X125-75S
At the top of the MA mini range sits the 63 mm MACJ63X125-75S: double-acting air power on both sides of a 16 mm rod, an extend stroke that trims across a full 75 mm window, and variable air cushions at each end. At 0.5 MPa it develops 1557.9 N forward and 1457.4 N back, rising to 2181.0 N and 2040.3 N at 0.7 MPa across a 30-800 mm/s speed band.
Budget about 935 N of that 0.5 MPa push for actual work and the cylinder will outlast any rating-driven sizing choice. The riveted stainless barrel and chrome-plated rod tolerate outdoor yards and damp food plants where painted minis corrode, and the standard piston magnet accepts CMSG, DMSG and EMSG switches straight from the box, no paid sensor option required.

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 MACJ63X125-75S Is Used
Pallet-station pusher
Pushes loaded tote pallets onto a gravity roller spur at a warehouse transfer point, using about 935 N of working force at 0.5 MPa.
Test-rig coupon clamp
Clamps steel test coupons in a hydraulic test rig; the 75 mm window handles coupons of varying thickness without re-shimming.
Lab press ram
Compacts powder samples in a small lab press, with the both-end air cushion protecting the platen at the bottom of each stroke.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X125-75S the Right Cylinder?
Nothing above 63 mm exists in this series, so if 981.3 N from a 50 mm bore is enough, save the air; if not, this is the final step. The 75 mm trim range helps when tooling height is still being finalised, but the screw is purely a stop: under gravity or lost air the piston still moves, so add a holding valve for overhead loads. FA flange or LB foot mounting, I and Y knuckles, and external guiding of the load keep the 16 mm rod straight through the full 125 mm of travel.
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 MACJ63X125-75S FAQ
Push at 0.5 MPa is 1557.9 N and pull at 0.5 MPa is 1457.4 N. At 0.7 MPa the push reaches 2181.0 N and the pull 2040.3 N, with a theoretical maximum of 317.7 kgf at 1.0 MPa. Double-acting, 63 mm bore, 16 mm rod.
The 63 mm bore takes 1/4" ports with PT (blank), G or NPT thread options, and the rod ends in an M14x1.5 male thread. Mounting covers the FA flange and LB foot, with I and Y rod knuckles available; adjustable-stroke models like this one carry no SDB or back-cover mount code, so pick FA or LB when ordering.
