Airtac MARF Stainless Steel Mini Air Cylinder MARF63X25S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X25S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 25mm 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 MARF63X25S
The 25 mm stroke MARF63X25S is AirTAC's largest round-body mini cylinder in its shortest trim: double acting, with a variable air cushion at both ends and a front-flange mount rolled into the front cover itself, so no separate flange plate is ordered. At 0.5 MPa it pushes about 1558 N and pulls about 1457 N, delivered by a riveted stainless barrel and a 16 mm rod hard-chrome plated to 20 um, a build that keeps rust out of damp or washdown-prone corners where painted minis fail.
Because the push rating is theoretical, plan real work at roughly 935 N (60 percent of the 0.5 MPa push figure), which still lifts about 79 kg vertically with a 2:1 margin. The magnet comes built in as standard, so CMSG, DMSG or EMSG switches clip straight onto the barrel for end-of-stroke signalling without a special 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 (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 MARF63X25S Is Used
CNC fixture clamping
Clamps a workpiece into a CNC turning fixture without a vise; about 935 N of usable force at 0.5 MPa holds steel parts through 25 mm of clamp travel.
Mold slide lock
Locks a sliding core in an injection mold between shots, with the 1/4 inch port feeding a cushion that damps the lock-in impact.
Packaging line stopper
Pops a stopper blade under cartons at an accumulation station, indexed by a CMSG switch riding on the standard magnet.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X25S the Right Cylinder?
The 25 mm stroke suits fixture clamping and short eject jobs rather than traversal. For loads under about 981 N at 0.5 MPa the 50 mm bore MAR costs less in compressed air; 63 mm is the top of the MAR range, so above this force class the related MAC family, which uses a separate flange or foot, takes over. The integrated front flange bolts straight to a machine plate, and the standard magnet accepts CMSG / DMSG / EMSG switches. Note the cylinder is double acting only: cut the air and the rod drifts, the cushion never holds load, so use a rod lock where position must be kept.
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 MARF63X25S FAQ
At 0.5 MPa it pushes 1557.9 N (about 1558 N) and pulls 1457.4 N; at 0.7 MPa push rises to 2181 N with pull at 2040 N. The theoretical maximum is 317.7 kgf at 1.0 MPa. The 63 mm bore uses 1/4 inch ports and an M14x1.5 male rod thread.
The barrel is stainless steel and the rod is carbon steel hard-chrome plated to 20 um, so splash, humidity and light washdown do not pit the body the way they do on painted mini cylinders. The aluminium covers are rolled onto the tube rather than screwed, which also keeps the joint sealed.
