Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 175mm 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 MACJ63X175-50S
Heavy pushes at 0.5 MPa start with a 63 mm bore and a clean round body: 1558 N on extend, 1457 N on retract, with a variable air cushion at both ends to tame 30-800 mm/s arrivals. The -50 window means one cylinder covers several machine variants -- the setter trims extend travel by up to 50 mm in place.
Construction earns its keep too: a stainless barrel rolled onto aluminium covers with a hard-chrome plated 16 mm rod, sealed for washdown spots. The magnet is standard, feeding CMSG / DMSG / EMSG switches, and the working budget is about 935 N at 0.5 MPa, equal to lifting roughly 79 kg vertically at a 2:1 margin.

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 MACJ63X175-50S Is Used
Case pusher on a shrink wrapper
Pushes loaded cases into the shrink tunnel; 1558 N keeps the row moving while the 50 mm window fine-tunes the push-off point.
Washdown lid clamp on a food kettle
Clamps a hinged kettle lid through daily hose-downs; the stainless barrel and chrome rod laugh off caustic foam.
Hopper gate on a blending line
Opens and closes a slide gate under powder head-load; the both-end cushion stops the gate from banging its frame.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X175-50S the Right Cylinder?
If 981 N at 0.5 MPa (a 50 mm MACJ) still does the job, save the air; otherwise this 63 mm bore is the ceiling of the MA family. Position comes from a hard mechanical stop, so if supply pressure drops nothing in the cylinder holds the rod -- pair it with a check or clamping valve for suspended loads. Match the frame with FA flange or LB foot, pick an I or Y knuckle for pivot links, and remember the sister types: MAJ (adjustable, bumper), MAC (fixed stroke with cushion) and MACD (double rod) when the duty changes.
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 MACJ63X175-50S FAQ
At 0.5 MPa: 1558 N push, 1457 N pull. At 0.7 MPa: 2181 N push, 2040 N pull. The theoretical maximum at 1.0 MPa is 317.7 kgf. Supply range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), ambient -20 to +70 C, speed 30-800 mm/s.
FA flange and LB foot mountings anchor the body, while I and Y rod knuckles handle pivoting links. The adjustable version carries no SDB or back-cover code, so plan the bracket around the stop screw end of the 175 mm body.
