Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X75-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X75-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 75mm 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 MACJ63X75-10S
At 75 mm of stroke, the MACJ63X75-10S adds reach while a narrow 10 mm window fine-trims the extend position - useful where the stroke must land within a millimetre or two. It is double-acting, cushioned at both ends, and delivers 1557.9 N push and 1457.4 N pull at 0.5 MPa.
Derate to about 935 N for continuous work - 60% of the 0.5 MPa push - which corresponds to lifting roughly 79 kg vertically with a 2:1 margin. Ports are 1/4", the rod thread is M14x1.5 on a 16 mm chromed rod, the riveted stainless body takes humid, wash-prone corners in stride, and the built-in magnet is standard for CMSG / DMSG / EMSG switches.

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 MACJ63X75-10S Is Used
Lift assist on an assembly mast
Raises a 65 kg welding fixture up a mast using the 935 N working push, comfortably inside the 79 kg vertical-lift envelope.
Belt take-up tensioner
Keeps a conveyor belt at even tension; the 10 mm trim compensates for belt stretch without repositioning the mount.
Glue press on a joinery bench
Presses veneer sheets evenly; 1557.9 N at 0.5 MPa across the platen with the cushion easing the clamp home.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X75-10S the Right Cylinder?
The 50 mm bore gives 981.3 N at 0.5 MPa and the 40 mm gives 628.3 N if the job is lighter; 63 mm is as big as the MA range goes, so step to another series for more. The 10 mm stop screw sets extend length precisely but is not a position lock - expect drift on air loss and add a locking or braking valve for elevated loads. Mount on an FA flange or LB foot, fit I or Y knuckles where the load pivots, and guide the 16 mm rod externally since the longer 75 mm stroke amplifies side loads.
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 MACJ63X75-10S 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; theoretical peak 317.7 kgf at 1.0 MPa. Pressure spans 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
Air ports are 1/4", the male rod thread is M14x1.5, and mounting choices are the FA flange or LB foot with optional I or Y rod knuckles. The magnet is built in as standard, so CMSG, DMSG and EMSG switches fit without special orders.
