Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm bore and 175mm stroke, 1/8" 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 MACJ20X175-20S
Need a light actuator that covers nearly 175 mm without growing in diameter? The bore 20 MACJ20X175-20S produces 157 N of push and 131.9 N of pull at 0.5 MPa while staying at Dia 20 barrel size. Its extend stroke is trimmed by a stop screw across a 20 mm range, with air cushioning adjustable at both heads.
Because the barrel is stainless and the rod hard-chrome plated, this riveted round-body mini tolerates humid cells and outdoor mounts that would corrode painted housings. Frame your duty at roughly 94 N of working push at 0.5 MPa, which translates to about 8 kg of vertical lift with a 2:1 margin. No magnet option is needed - every unit ships with one fitted for CMSG, DMSG or EMSG position 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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MACJ20X175-20S Is Used
Parcel sorting flap
Throwing a divert flap on a small parcel sorter; at 0.7 MPa the bore 20 delivers 219.8 N, ample for lightweight totes cycling at speed.
Slitter web tension arm
Loading a dancer arm on a narrow-web slitter, where the cushion absorbs arm oscillation and the chrome-plated rod resists paper dust abrasion.
Jig clamp fixture
Clamping aluminium extrusions in a bench welding jig across a 155-175 mm throat, adjusted on the machine without changing the cylinder.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-20S the Right Cylinder?
Next sizes up and down: bore 16 pushes 100.5 N and bore 25 pushes 245.3 N, both at 0.5 MPa, bracketing this model's 157 N. Long 175 mm travel on a slender 8 mm rod means bending grows quickly - keep thrust axial, or add an external linear guide when the load overhangs.
FA flange or LB foot mounting matches most machine frames, and I / Y knuckles are there for linkages. The adjustable stop defines the extend position but offers no clamping - under air loss the piston can creep, so use a pilot-checked or shut-off valve wherever the position must persist.
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 MACJ20X175-20S FAQ
Bore 20, 175 mm stroke, 20 mm adjust window. Force: 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, 32 kgf theoretical max at 1.0 MPa. Pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
An FA flange bolts the front cover to a machine face, an LB foot bolts the body to a base plate, and I or Y rod knuckles suit swinging linkages. Because the barrel is riveted, none of these require drilling the tube, keeping the seal intact.
