Airtac MARF Stainless Steel Mini Air Cylinder MARF40X30S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF40X30S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø40mm bore and 30mm 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 MARF Stainless Steel Mini Air Cylinder MARF40X30S
Tight-envelope actuation is the brief here: a 30 mm stroke, bore 40 push of 628.3 N (527.8 N pull) at 0.5 MPa, and a front flange rolled into the MAR body itself so nothing extra bolts beside it. Double acting with variable cushion at each end, it runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) clean dry air filtered to 40 um.
Round stainless barrel, 20 um hard-chrome on the carbon-steel rod, riveted aluminium covers - a package that resists the washdown and light chemicals that ruin painted minis. For duty planning, treat about 377 N as the working push (60 percent of rating) and match vertical loads to roughly 32 kg lifted with a 2:1 margin. The magnet comes standard: drop a CMSG / DMSG / EMSG switch on the barrel for position feedback.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MARF Stainless Steel Mini Air Cylinder MARF40X30S Is Used
Index pin on a rotary dial table
A 30 mm stroke drops and retracts an indexing pin; 628 N seats it firmly and the cushion kills the seat rattle at 200 cycles a minute.
Ejector on an SMD tray stamper
Front-flange mount fits flush behind the die; the short throw flips finished PCB trays off the stack without overshooting the chute.
Presence kick on a filling head
The standard magnet and an EMSG switch confirm cap seating on each bottle before the capper indexes, using the 30 mm return stroke.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF40X30S the Right Cylinder?
Next bore up or down: 32 mm MAR delivers 402.2 N at 0.5 MPa while 63 mm reaches 1557.9 N - pick 40 mm when 628.3 N meets the job. A 30 mm stroke has little rod exposure, so bending is rarely a concern, but keep loading pure axial anyway. It will not hold against air loss - the cushion is shock control, not a brake - so specify a rod lock for gravity loads. It takes the same I / Y knuckles on the M12x1.25 rod as the rest of the series.
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 MARF Stainless Steel Mini Air Cylinder MARF40X30S FAQ
Push 628.3 N and pull 527.8 N at 0.5 MPa; push 879.6 N and pull 738.9 N at 0.7 MPa; theoretical maximum 128.1 kgf at 1.0 MPa. Operating window is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, air filtered to 40 um, speed 30-800 mm/s, temperature -20 to +70 C.
The riveted stainless barrel with hard-chrome rod survives damp, food-grade and outdoor settings that pit painted aluminium minis, while the 30 mm stroke keeps the envelope tight. Both-end variable cushion is tuned by needle screws on commissioning, and the front flange is already part of the cylinder body, so nothing extra goes on the mounting face.
