Airtac MARF Stainless Steel Mini Air Cylinder MARF50X450S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X450S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 450mm 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 MARF50X450S
The 450 mm stroke on this MARF50X450S gives the 50 mm MAR bore room for long feeds while the front flange bolts straight to the machine, with no separate foot or bracket to buy. Double acting with a variable air cushion at both ends, it pushes 981 N and pulls 881 N at 0.5 MPa, rising to 1374 N and 1233 N at 0.7 MPa from a bore rated 200.1 kgf at maximum theoretical pressure.
The riveted stainless round barrel and 16 mm hard-chrome rod handle damp, washdown-prone spots better than painted minis. Expect about 589 N of usable work at 0.5 MPa once you de-rate to 60 percent, and the dual cushion needles let you trim end-of-stroke shock so 30-800 mm/s travel stays smooth. A magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on anytime.

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 MARF50X450S Is Used
Roller conveyor ejector
A 450 mm throw clears a full pallet width in one move; 981 N at 0.5 MPa slides packed cartons off the line and the cushions stop the end-of-stroke bang.
Textile batch feeder
Feeds a roll of fabric into a cutting gantry each cycle, with CMSG switches confirming the extended and retracted positions.
Chute gate actuator
Drops a slide gate on a grain chute; the 16 mm hard-chrome rod and stainless barrel shrug off dusty, damp elevator air.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X450S the Right Cylinder?
If 981 N at 0.5 MPa is more than the job needs, the 40 mm MAR gives 628 N push and 528 N pull on 1/8" ports; if you need up to 1558 N, step to the 63 mm bore. Both keep the same 30-800 mm/s speed band and 0.15-1.0 MPa (22-145 psi) supply. This 450 mm stroke is standard, so nothing is made to order, and CMSG or DMSG switches snap onto the barrel wherever a position check is needed.
The flange is already part of the front cover, so MAR does not take separate FA, LB or SDB feet, though I and Y knuckles still thread onto the M14x1.5 rod. Note the plain cylinder drifts if air is lost; add a rod lock where position must hold.
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 MARF50X450S FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa, 1374 N push and 1233 N pull. The theoretical maximum for the 50 mm bore at 1.0 MPa is 200.1 kgf. Porting is 1/4" and the rod thread is M14x1.5 on a 16 mm rod.
Yes. Every MA-series cylinder has a magnet in the piston as standard, so CMSG, DMSG and EMSG switches mount directly on the barrel without a special-order piston. Adjust the cushion needles and set speed between 30 and 800 mm/s before wiring the switch positions.
