Airtac MARF Stainless Steel Mini Air Cylinder MARF50X650S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X650S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 650mm 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 MARF50X650S
A 50 mm MAR from AirTAC converts 0.5 MPa shop air into 981 N of forward force and 881 N back on the retract stroke, delivered by a double-acting piston with an adjustable air cushion at each end. The F code builds the front flange into the cover itself, so the cylinder bolts to the machine frame with no loose flange accessory, and the 650 mm stroke is rolled to order beyond the 500 mm standard range.
Around that piston sits a stainless round barrel with a hard-chrome plated rod and riveted aluminium covers, a combination that shrugs off splash, humidity and mild washdown where painted mini cylinders blister. The cushion needles at both ends dial out end-of-stroke shock, so heavier loads can travel faster without hammering the covers. Practical push at 0.5 MPa sits near 589 N, which translates to about 50 kg of vertical lift once a 2:1 margin is applied; the magnet ships factory-fitted, so CMSG, DMSG or EMSG switches clip on whenever position signals are needed.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MARF50X650S Is Used
Juice line tray pusher
Sweeps filled 6 L juice trays off a washdown conveyor into a crate, the variable cushion landing each push without jolt.
Coastal weld-fixture lift
Raises a 45 kg fixture through a 650 mm transfer height, the 2:1 margin already inside the 50 mm bore's 981 N rating.
Dairy case packer gate
Acts as a splash-zone gate on a dairy case packer, the stainless barrel resisting the daily caustic rinse-down.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X650S the Right Cylinder?
Between a 40 mm bore (628 N push at 0.5 MPa) and the 63 mm flagship (1558 N), the 50 mm sits in the workhorse middle - pick it for pushes and clamps in the 400-550 N working band. At 650 mm this stroke is made to order rather than catalog standard, and the 16 mm rod should never see side thrust: guide the load externally on travels this long.
The front flange is integral, the 1/4" ports are PT as standard with G and NPT orderable, and both cushion needles deserve a pass at commissioning. On air failure the rod coasts freely - the cushion damps the stroke end but parks nothing - so add a rod lock if the position must hold. The standard magnet accepts CMSG, DMSG or EMSG switches without modification.
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 MARF50X650S FAQ
At 0.5 MPa the 50 mm bore pushes 981.3 N and pulls 880.8 N; at 0.7 MPa that rises to 1373.8 N push and 1233.1 N pull, with a theoretical maximum of 200.1 kgf at 1.0 MPa. Air supply runs 0.15-1.0 MPa (22-145 psi) and the cushioned rod strokes 650 mm at 30-800 mm/s. Ports are 1/4" and the rod thread is M14x1.5.
Yes. The barrel is stainless steel and the rod is hard-chrome plated carbon steel, so splash, humidity and mild detergents will not eat it the way they attack painted minis. The needle screws at both ends tune the variable cushion: start half open, then close gradually until the end-of-stroke knock disappears.
