Airtac MARF Stainless Steel Mini Air Cylinder MARF25X200S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF25X200S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø25mm 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 MARF Stainless Steel Mini Air Cylinder MARF25X200S
The MARF25X200S pairs a 25 mm bore with a 200 mm stroke in AirTAC's riveted round-body MA format: double acting, variable air cushion at both ends, and built around an integrated front-flange bracket that bolts straight to the machine plate. Push force reaches 245.3 N at 0.5 MPa (206.1 N on return), rising to 343.4 N at 0.7 MPa with a theoretical ceiling of 50 kgf. It runs on 0.15-1.0 MPa (22-145 psi) of filtered air at 30-800 mm/s.
For real work, budget roughly 147 N of continuous push at 0.5 MPa - in lifting terms about 25 kg vertical, or 12.5 kg once a 2:1 margin is kept. The stainless barrel and 20 um hard-chrome plated 10 mm rod shrug off condensation and mild washdown that pit painted minis, and the standard built-in magnet lets CMSG, DMSG or EMSG switches clip on without a special-order piston.

Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MARF25X200S Is Used
Bottling flap gate
The 200 mm stroke swings a diverter flap between two lanes of a 12-head bottling conveyor; the cushioned stop saves the gate at cycling speeds up to 800 mm/s.
Tray lift in assembly cells
245.3 N at 0.5 MPa hoists an aluminium housing tray of about 12 kg between bench and tote, with the front flange carrying the load straight into the frame.
Dairy CIP diverter
Pushing a rinse diverter in a dairy clean-in-place skid: the stainless barrel and chrome rod take the daily caustic washdown that ruins painted bodies.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF25X200S the Right Cylinder?
Step down to a 20 mm MAR (157.0 N push at 0.5 MPa) for lighter clamps, or up to the 32 mm bore (402.2 N) when 245.3 N sits too close to your load. Like any un-locked pneumatic cylinder, the rod drifts if air pressure drops - add a rod lock where the position must survive a power cut. The front flange handles mounting, and with 200 mm of stroke on a 10 mm rod, external guides should take any side load.
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 MARF25X200S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa, 343.4 N push and 288.5 N pull. The theoretical maximum at 1.0 MPa is 50 kgf. Bore is 25 mm with a 10 mm rod, 1/8" air port and M10x1.25 male rod thread.
No. The MARF25X200S front cover carries its own flange, so it bolts directly to the machine plate with no separate flange or foot to order. The magnet is also built in as standard, so CMSG, DMSG or EMSG switches drop straight onto the barrel.
