Airtac MAC Stainless Steel Mini Air Cylinder MAC20X200SCMH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X200SCMH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 200mm 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 MAC Stainless Steel Mini Air Cylinder MAC20X200SCMH
Two hundred millimetres of travel from a bore only 20 mm wide is the MAC20X200SCMH proposition: 157 N of push at 0.5 MPa (220 N at 0.7 MPa) carried down a stainless tube by an 8 mm hard-chromed rod. Covers and the stainless block are rolled onto the barrel, a joint that stays tight through humidity, splash and repeated wipe-downs where painted minis peel.
End-of-stroke shock is dialed out by the variable air cushion at both ends - back the needle screws fully off at commissioning, then close them gradually until the load settles quietly. The standard piston magnet pairs with CMSG, DMSG or EMSG switches for mid-stroke sensing. Budget about 94 N of usable push at 0.5 MPa; that derated figure still lifts roughly 8 kg vertically with 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 (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 MAC Stainless Steel Mini Air Cylinder MAC20X200SCMH Is Used
Food-tray lidding clamp
Presses lidding film taut on a 250 g ready-meal tray; the stainless body shrugs off daily caustic washdown between shifts.
Vision probe lower-down
Lowers a 600 g camera probe 200 mm into an inspection nest on an electronics line, cushioned so the lens never slams home.
Print-apply tamp head
Drives a label tamp pad onto cartons at a warehouse print-apply station, the 200 mm reach clearing the conveyor edge each cycle.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X200SCMH the Right Cylinder?
Compare before committing: a 16 mm bore reaches only 100.5 N push at 0.5 MPa, while a 25 mm bore offers 245.3 N if the 20 mm working band near 94 N feels thin. Over 200 mm of stroke, run the load on an external guide rather than leaning on the 8 mm rod. When air pressure drops, the piston drifts freely - a pilot check valve or rod lock holds position instead. Ports measure 1/8" and the rod thread is M8x1.25; the trailing H in the model code is not one of the standard PT/G/NPT thread letters, so confirm its meaning from the datasheet before ordering. FA flange, LB foot and SDB pivot brackets cover fixed and pivoted frames, with I and Y knuckles for the rod end.
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 MAC Stainless Steel Mini Air Cylinder MAC20X200SCMH FAQ
The bore develops 157 N push and 132 N pull at 0.5 MPa, rising to 220 N and 185 N at 0.7 MPa; the theoretical maximum is about 32 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) of 40 um filtered air, tolerates 1.5 MPa (215 psi) proof pressure, strokes at 30-800 mm/s and works from -20 to +70 C.
No - with both chambers vented the piston drifts, and the air cushion is a shock absorber, not a brake. Add a pilot check valve for short holds or specify a rod-lock cylinder where a load must stay put unpowered.
