Airtac MARF Stainless Steel Mini Air Cylinder MARF63X50S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X50S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 50mm 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 MARF63X50S
A 63 mm bore with the mounting flange already rolled onto its front cover, the MARF63X50S is AirTAC's MA-series round mini cylinder: double acting, variable air cushion at both ends, nothing extra to bolt on. Pushing from full bore area it delivers 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa, the highest output in the MA range.
The riveted stainless barrel and hard-chrome plated rod shrug off washdown and damp air that pit painted mini cylinders. Size real work at about 935 N per cycle at 0.5 MPa; hung vertically with a 2:1 margin it lifts roughly 79 kg. The magnet is built in, so CMSG, DMSG or EMSG switches drop straight on.

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 MARF63X50S Is Used
Small press ram
Stakes or chamfers bushings on a 50 mm stroke, with the variable cushion soaking up the impact at bottom dead center.
Weld fixture clamp
Clamps sheet steel jigs near the weld cell, where the stainless barrel resists spatter, coolant mist and grinding dust.
Hopper gate pusher
Opens the slide gate on a 50 kg ingredient hopper with a 2:1 vertical margin, position confirmed by a CMSG switch.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X50S the Right Cylinder?
At the top of the 20-63 mm MA range, this bore nearly doubles the 981.3 N push of the 50 mm model at 0.5 MPa - step down to MARF50 if 1558 N is more than the job needs. On air loss the piston simply drifts; a rod lock is the fix when position must hold. The front flange bolts directly to the machine frame, I and Y knuckles thread onto the M14x1.5 rod, and ports are 1/4 inch with PT standard or G and NPT to order.
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 MARF63X50S FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa, 2181.0 N push and 2040.3 N pull. Theoretical maximum at 1.0 MPa is 317.7 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
No. The F in MARF63X50S means the front-flange bracket is integrated into the front cover and rolled in place with the body - there is no separate flange part to buy or align. Rod knuckles in I and Y styles still fit the M14x1.5 male thread.
