Airtac MARF Stainless Steel Mini Air Cylinder MARF50X100S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF50X100S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø50mm bore and 100mm 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 MARF50X100S
The flange is not an add-on here; it is part of the front cover, so the MARF50X100S sits flush against a machine plate with nothing extra to align. This double-acting 50 mm mini swings 981 N on extend and 881 N on retract at 0.5 MPa, with adjustable cushion needles at both ends over the 0.15-1.0 MPa (22-145 psi) supply range and 30-800 mm/s speeds.
In lift terms, 981 N balances about 100 kg, so keep vertical picks near 50 kg to hold a 2:1 margin. The stainless barrel and hard-chromed 16 mm rod handle damp, food-grade and outdoor air better than painted-steel minis, and the standard magnet accepts CMSG / DMSG / EMSG switches anywhere along the 100 mm stroke.

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 MARF50X100S Is Used
Machining pallet clamp
Holding aluminium gearbox housings on a CNC pallet against cutting reaction; 981 N of clamp force holds where a 40 mm cylinder at 628 N would let the part chatter.
Curing tray lift
Raising a 45 kg curing tray at an unload station; the 2:1 vertical margin keeps the pick inside the roughly 50 kg guideline for this bore.
Case packer ejection
Ejecting filled cases from a case packer into a takeaway conveyor; the 100 mm stroke clears the case depth and cushions protect the packer frame.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF50X100S the Right Cylinder?
Compare before you commit: 40 mm gives 628 N at 0.5 MPa and 63 mm jumps to 1558 N, so this 50 mm bore is the mid-size workhorse of the MAR range. If your machine needs a foot or a separate flange layout instead, the MAC series offers those mounts in the same force class. Retraction pulls 881 N at 0.5 MPa through 1/4" ports, and the integral flange means zero mounting accessories 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 MARF50X100S FAQ
Extension delivers 981 N and retraction 881 N at 0.5 MPa. At 0.7 MPa extension reaches 1374 N and retraction 1233 N. The theoretical ceiling is 200 kgf at 1.0 MPa. Connections are 1/4" ports with an M14x1.5 rod thread, and the 100 mm stroke is within the 500 mm standard range.
Yes, better than painted minis. The barrel is stainless steel, the 16 mm rod is hard-chrome plated to about 20 um, and the covers are aluminium alloy - a combination that resists rust from mist, splashes and outdoor exposure. Rinse with mild detergent, dry the rod, and grease stays stored in the two-way piston seal between services.
