Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X100-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X100-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MACJ20X100-100S
One hundred millimetres of stroke, all of it trimmable through the 100 mm window, makes the MACJ20X100-100S a one-cylinder-fits-several-jobs pick on packaging and assembly lines. It is double-acting with a variable air cushion at both ends, running on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s. The riveted stainless barrel and hard-chrome plated rod stand up to washdown and damp plant air where painted minis would corrode.
At 0.5 MPa the bore pushes 157.0 N and pulls 131.9 N; at 0.7 MPa push climbs to 219.8 N, peaking at 32.0 kgf theoretically. Budget about 94 N for real work at 0.5 MPa, and count on roughly 8 kg of vertical lift once a 2:1 safety margin is applied. A magnet comes built in as standard, so CMSG / DMSG / EMSG switches mount without modification.

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 MACJ20X100-100S Is Used
Tray pick-up on oven line
Lifts cookie trays off the oven conveyor with suction cups, handling about 8 kg vertically with margin; the 100 mm window matches tray depth.
Spray-gun carrier slide
Carries a small paint spray gun across a 100 mm pass in a finishing booth, with the cushion preventing gun kick at stroke end.
Fabric bolt loader
Pushes rolled fabric bolts onto a winding cart in a textile store; the stainless body shrugs off lint-laden, humid air.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X100-100S the Right Cylinder?
Size up or down by force: the 16 mm bore offers 100.5 N at 0.5 MPa while a 25 mm bore nearly doubles that to 245.3 N. Over 100 mm of stroke, watch side loads - misalignment bends an 8 mm rod faster than force does, so guide the load or use an I or Y knuckle. FA flange, LB foot, and a standard magnet for DMSG / CMSG / EMSG switches round out the fitting options. The adjustable stop only shortens the extend stroke; on air loss the piston is free to move, so do not rely on it to park a load.
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 MACJ20X100-100S FAQ
At 0.5 MPa: 157.0 N push, 131.9 N pull. At 0.7 MPa: 219.8 N push, 184.7 N pull. The theoretical ceiling at 1.0 MPa is 32.0 kgf. Working pressure is 0.15-1.0 MPa (22-145 psi), and with the 100 mm adjust window you can set the extend stroke anywhere below 100 mm.
The magnet ships standard on all MA cylinders, so CMSG / DMSG / EMSG switches sense end positions along the stainless barrel without special ordering. The variable air cushion at both ends matters more as stroke grows: it decelerates the load so the covers are not hammered at 30-800 mm/s speeds.
