Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X150-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X150-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 150mm 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 MACJ63X150-75S
Where a load must land in exactly the right spot, the MACJ63X150-75S gives 150 mm of travel with a 75 mm trim range on the extend stroke. This double-acting mini cylinder also carries a variable air cushion at each end, so you can shorten the stroke and soften the stop without touching the air supply. Thrust at 0.5 MPa reaches 1557.9 N on extend, close to 159 kg of straight push.
The stainless round barrel with its hard-chrome rod tolerates washdown that kills painted-steel minis, and the aluminium covers are rolled onto the tube for a sealed joint. AirTAC fits the magnet as standard equipment, so CMSG / DMSG / EMSG switches can be added at any time. At 0.7 MPa extend force climbs to 2181.0 N; run it anywhere from 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MACJ63X150-75S Is Used
Carton flap press station
Presses flap-closing tabs on shipper cartons; the 75 mm window sets press depth per carton size, and the cushion absorbs the hit at end of stroke.
Sliding guard door on band saws
Actuates the steel guard over a saw cutting zone; the standard magnet feeds an EMSG switch so the interlock reads door-open state directly.
Press die ejector
Pushes finished blanks clear of a draw die after each cycle; 1457.4 N of pull at 0.5 MPa retracts the plunger promptly for the next shot.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X150-75S the Right Cylinder?
The 63 mm bore is the ceiling of the MA series, so compare downward: a 50 mm bore gives 981.3 N at 0.5 MPa, which suits lighter gates, while this unit reserves 1557.9 N for stiff clamps and lifts. The 75 mm window suits dial-in commissioning on lines where the final stop position is tuned after install. Choose FA flange or LB foot mounting; I and Y knuckles cover rod-end articulation. The stroke screw is an end stop, not a lock, so a dropped air line lets the rod drift - block the flow with a valve when holding matters.
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 MACJ63X150-75S FAQ
Extend force is 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa; retract is 1457.4 N at 0.5 MPa and 2040.3 N at 0.7 MPa. Theoretical peak at 1.0 MPa is 317.7 kgf. Ports are 1/4", the rod is 16 mm with M14x1.5 male thread, and the adjustable window on this model is 75 mm on the extend stroke.
The barrel is stainless steel and the rod carries a 20 um hard-chrome plating, so rinse water and humid air do not chew the surfaces the way they do on painted minis. Covers are rolled onto the tube, keeping the riveted joint sealed. The magnet comes standard, ready for CMSG / DMSG / EMSG switches.
