Airtac MARF Stainless Steel Mini Air Cylinder MARF50X35S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X35S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 35mm 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 MARF50X35S
Short-stroke punching and clamping at half-kilonewton level is the job of the MARF50X35S: a 50 mm bore driving a 16 mm hard-chrome rod over just 35 mm, pushing 981.3 N at 0.5 MPa and 1373.8 N at 0.7 MPa. The round stainless barrel is rolled onto aluminium-alloy covers, giving a riveted, sealed body that survives washdown better than painted-steel minis. It runs double acting on 0.15-1.0 MPa (22-145 psi) air at 30-800 mm/s.
A variable air cushion sits at both stroke ends - turn the needle screws on commissioning and end-of-stroke shock disappears even on fast cycles. The front-flange bracket is machined into the front cover, so no separate foot or flange is ordered. For load planning, budget about 589 N of real working force at 0.5 MPa, close to lifting 50 kg vertically with a 2:1 margin, and rely on the standard piston magnet to run CMSG, DMSG or EMSG sensors.

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 MARF50X35S Is Used
Date-code stamp
Prints date codes onto dairy tub lids; 35 mm is exactly the kiss-and-retract travel a print head needs.
CNC fixture clamp
Clamps aluminium brackets against a machining jig with about 589 N of practical holding force at 0.5 MPa.
Pump bearing press
Seats small bearings into pump housings on an assembly bench using the 1373.8 N available at 0.7 MPa.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X35S the Right Cylinder?
If 981.3 N at 0.5 MPa is more than the task needs, the 40 mm bore delivers 628.3 N in the same MA family; if the clamp needs more bite, the 63 mm bore gives 1557.9 N. Keep in mind this cylinder has no position lock: cut the air and the piston simply coasts, since the cushion only softens the end of travel, so fit a rod lock where holding matters. The integrated F front flange bolts straight to the fixture, I or Y knuckles fit the M14x1.5 rod, and 1/4" ports feed both chambers.
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 MARF50X35S FAQ
Push at 0.5 MPa is 981.3 N and pull is 880.8 N; at 0.7 MPa the push reaches 1373.8 N. Theoretical maximum at 1.0 MPa is 200.1 kgf. Bore 50 mm, stroke 35 mm, 16 mm rod with M14x1.5 thread, 1/4" ports.
Yes - the 35 mm travel runs inside a high-precision stainless-steel tube with a hard-chrome plated (20 um) carbon-steel rod, so splash, humidity and mild washdown chemicals do not pit the working surfaces the way they do on painted minis.
