Airtac MARF Stainless Steel Mini Air Cylinder MARF63X400S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X400S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 400mm stroke, 1/4" 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 MARF63X400S
A front-flange mini cylinder that still hits big-bore numbers: the MARF63X400S runs double acting on a 63 mm bore with a variable air cushion at both ends, and the flange is rolled into the front cover so the body bolts straight onto a machine wall or fixture with no added bracket. At 0.5 MPa it delivers about 1558 N on the extend stroke and 1457 N retracting, rising to 2181 N if you feed it 0.7 MPa. Stroke is 400 mm on a 16 mm hard-chrome plated rod with 1/4" ports.
The riveted stainless barrel shrugs off washdown and damp air far better than painted-steel minis, and because the piston magnet is built in as standard you can clip a CMSG, DMSG or EMSG switch anywhere along the tube without special ordering. For sizing, keep real work under roughly 935 N at 0.5 MPa - about 60 percent of the push rating - and in lift terms the rod raises around 79 kg vertically with a 2:1 margin. Trim the cushion needles on first run so the long stroke settles without hammering the covers. Speed range is 30-800 mm/s over 0.15-1.0 MPa (22-145 psi).

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MARF63X400S Is Used
Die Ejector on a Press Table
A 400 mm stroke strips a deep formed bracket out of a bending die in one pull; 1558 N at 0.5 MPa clears the part while the cushion stops the rod snapping home at stroke end.
Lift Gate on a Bottling Line
Raising a 60 kg accumulator gate vertically: the bore hoists about 79 kg with a 2:1 margin, so the gate lifts briskly even at half supply pressure.
Pallet Diverter on a Roller Conveyor
Mounted flange-down beside the track, the cylinder shoves a loaded pallet car onto a spur line; about 935 N of practical push walks a 200 kg cart through greased rollers.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X400S the Right Cylinder?
Step down to the MARF50X400S if 981 N at 0.5 MPa covers your load; the 63 mm bore is the largest in the MAR range, so if 1558 N falls short, move to 0.7 MPa (2181 N) or a bigger platform. At 400 mm of stroke, guide the load in its own bearings or pick a coupling that absorbs misalignment, since side loads bend a 16 mm rod long before the barrel complains.
This flange-mounted version holds the cylinder rigid but does not hold position when air is lost - the piston drifts freely, so fit a rod lock or an external stop if the load must stay put mid-stroke.
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 MARF63X400S FAQ
At 0.5 MPa the 63 mm bore pushes 1558 N and pulls 1457 N. Raise the supply to 0.7 MPa and those become 2181 N push and 2040 N pull. The theoretical maximum is 317.7 kgf at 1.0 MPa. It is double acting with a variable cushion at each end.
No. Every MARF63X400S ships with the piston magnet already fitted as standard on the MA platform, so CMSG, DMSG and EMSG switches mount anywhere along the stainless barrel and clamp on without disassembly.
