Airtac MARF Stainless Steel Mini Air Cylinder MARF40X130S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF40X130S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø40mm bore and 130mm 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 MARF40X130S
A 40 mm bore MAR with 130 mm of travel and its own front-flange bracket rolled onto a stainless round barrel, this cylinder pushes 628 N and pulls 528 N at 0.5 MPa across a 0.15-1.0 MPa (22-145 psi) working range. The hard-chrome plated 16 mm rod shrugs off washdown and damp shop air better than painted-steel or aluminium minis. Air cushions at both ends are adjustable, so a 130 mm stroke can still land a heavy part gently at speeds up to 800 mm/s.
For sizing, treat roughly 377 N of push as your working figure at 0.5 MPa instead of the full 628 N rating; in vertical terms the full rating equals about 64 kg, so lifting more than 32 kg invites a thin margin. The magnet is fitted as standard, so CMSG, DMSG or EMSG switches clip straight onto the barrel for end-of-stroke signalling without a special-order piston.

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 MARF40X130S Is Used
Bottle rejection gate on a filling line
The 130 mm swing and 628 N push snap a reject arm across a bottle lane, and the stainless barrel tolerates daily washdown in the bottling hall.
Bench press for grommet insertion
Around 377 N of usable push at 0.5 MPa seats rubber grommets into sheet-metal panels, with the cushioned bottom of stroke preventing shock on the tooling.
Box stopper at a palletizing station
Flange-mounted at the end of a roller conveyor, the rod extends 130 mm to stop cartons, while a DMSG switch confirms the gate has fully deployed.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF40X130S the Right Cylinder?
If 628 N of push at 0.5 MPa is more than the job needs, the 32 mm bore MARF32 gives 402 N; if the load climbs past 900 N, step up to the 50 mm bore at 981 N. Note the MAR drifts when air is lost - the cushion only softens the stroke ends, so fit a rod lock if the position must hold.
Mounting is built in: the F code front flange bolts straight to the machine face without a separate foot or bracket accessory. On a 130 mm stroke, keep side loads low or guide the load externally to protect the 16 mm rod and its seals.
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 MARF40X130S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those figures rise to 879.6 N and 738.9 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. Ports are 1/8" on this 40 mm bore, and the 16 mm rod carries an M12x1.25 male thread.
The F code means the flange bracket is riveted onto the barrel at the factory - bolt it to the machine face and no separate foot or flange part is needed. Every MARF40X130S carries a built-in magnet, so CMSG, DMSG and EMSG reed switches fit directly without ordering a special piston.
