Airtac MARF Stainless Steel Mini Air Cylinder MARF50X500S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X500S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 500mm 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 MARF50X500S
Maximum standard stroke for the 50 mm MAR bore is 500 mm, and MARF50X500S delivers it with a front flange already rolled into the body. Running on 0.15-1.0 MPa (22-145 psi) air, it pushes 981 N and pulls 881 N at 0.5 MPa; at 0.7 MPa those figures climb to 1374 N and 1233 N, with 200.1 kgf as the theoretical maximum.
Because the aluminium covers and stainless block are riveted onto the stainless tube, the cylinder shrugs off splash and outdoor air that corrodes painted housings. Halve the 981 N push for a 2:1 margin and you can lift about 50 kg vertically at 0.5 MPa. The standard magnet means position feedback with CMSG / DMSG / EMSG switches needs no special piston.

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 MARF50X500S Is Used
Case packer pusher
Pushes a completed 12-bottle case off the pack table; 1374 N at 0.7 MPa handles overfilled cartons without stalling.
Order-pick gate
Swings a picking lane gate across a 500 mm span, with the integral flange bolting to the guard rail in minutes.
Carousel index assist
Assists a rotating parts carousel into home; cushioned stops keep the 30-800 mm/s move quiet at each end of travel.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X500S the Right Cylinder?
Compare before you buy: the 40 mm MAR makes 628 N push and 528 N pull at 0.5 MPa, and the 63 mm bore reaches 1558 N push and 1457 N pull, so 50 mm at 981 N / 881 N sits mid-range. 500 mm is the longest standard stroke this bore takes; anything beyond that becomes a made-to-order build.
Port size is 1/4" on both 50 and 63 mm bores. The front flange is integral, so there is no separate flange or foot accessory, and position feedback needs no option code because the piston magnet is standard and takes CMSG / DMSG / EMSG switches. Because the piston is not latched, a sudden air loss lets the load drift; fit a rod lock if holding matters.
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 MARF50X500S FAQ
At 0.5 MPa: 981 N push and 881 N pull. At 0.7 MPa: 1374 N push and 1233 N pull. Theoretical maximum at 1.0 MPa for the 50 mm bore: 200.1 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi).
The barrel is drawn stainless steel and the 16 mm piston rod is hard-chrome plated to 20 um, with aluminium-alloy covers riveted on in a rolling-packed round body that resists splash, humidity and outdoor exposure far better than painted-steel minis. There are no tie rods, so nothing loosens after repeated washdowns.
