Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X160-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X160-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 160mm 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 MACJ63X160-40S
Big force from a small round body - the 63 mm bore develops 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa yet keeps the mini footprint crowded frames need. The extend stroke is adjustable across a 40 mm window by the external stop screw, and the variable air cushion at both ends lets you run 30-800 mm/s into heavy tooling without hammering the covers.
A stainless barrel with a 20 um hard-chrome plated 16 mm rod shrugs off the daily washdown that pits painted mini cylinders within months in food or outdoor cells. Derated for safety, the 0.5 MPa push is worth about 79 kg of vertical lift - headroom for lifting kettle lids or die halves twice the working weight. Fluid is air filtered to 40 um at 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 MACJ63X160-40S Is Used
Food kettle lid lift
Lids on 200 L cooking kettles lift well inside the 79 kg derated lift figure, while stainless shrugs off daily hose-downs.
Suspension bushing press
Press-fits flanged bushings into control arms at 0.7 MPa; the 40 mm window adapts the stroke per arm variant.
Pallet-flow stopper
Raises and lowers the stop on a pallet-flow lane, an LB foot carrying the reaction and a DMSG proving position.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X160-40S the Right Cylinder?
Drop to the 50 mm bore (981.3 N push at 0.5 MPa) for lighter work; there is no bore above 63 mm in this range, so this is the ceiling. One caution: the stop screw fixes where the extend stroke ends, it does not arrest a load if pressure drops, so clamp separately wherever a part must stay put. Choose the FA flange for rigid frames or the LB foot for base plates, fit I or Y knuckles when the load pivots, and note the magnet is already fitted for CMSG, DMSG and EMSG switches. Long 160 mm strokes with 1558 N behind them deserve external side-load guiding to protect the hard-chrome rod.
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 MACJ63X160-40S FAQ
At 0.5 MPa the bore pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa that becomes 2181.0 N push and 2040.3 N pull; the theoretical ceiling is 317.7 kgf at 1.0 MPa. It runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) with 1/4" ports, cushioned both ends, extend stroke trimmable across a 40 mm window below 160 mm.
Each end cover carries an adjustable cushion: a needle screw meters the trapped air in the last millimetres of travel, so you can soften hard landings when running at the top of the 30-800 mm/s range or driving heavy tooling. Turn the screw in for a gentler stop, out for a snappier cycle.
