Airtac MARF Stainless Steel Mini Air Cylinder MARF63X75S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X75S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 75mm 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 MARF63X75S
Seventy five mm of travel from the strongest mini bore AirTAC builds: the MARF63X75S is a double acting MA cylinder with a variable cushion at both stroke ends and its front flange formed into the front cover. Full-bore output is 1557.9 N at 0.5 MPa (1457.4 N pulling) and 2181.0 N at 0.7 MPa.
Both cushion needles are adjustable on first run, so a punch or gate can arrive gently even when driven at up to 800 mm/s. Count on roughly 935 N of usable push per cycle at 0.5 MPa; as a vertical lifter with a 2:1 margin that is about 79 kg. The piston magnet ships as standard, ready for CMSG, DMSG or EMSG reed 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MARF63X75S Is Used
Case ejector
Kicks formed cartons off a forming head across 75 mm, the dual cushions damping the release at both ends of the cycle.
Mix drum tilt
Tilts a 70 kg lab-scale drum between load and dump with the flange bolted to the frame and a CMSG switch confirming each end.
Die cart stop
Extends and retracts a stop blade for die carts on a press line; 2181.0 N at 0.7 MPa stands up to repeated cart impact.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X75S the Right Cylinder?
If 75 mm of stroke must move serious load, this 63 mm flange model is the ceiling of the range; the next size down, the 50 mm bore, manages 981.3 N at 0.5 MPa. Unpowered, the rod settles wherever load and friction leave it - a rod lock cylinder is the answer for hold-in-place duty. Keep external side load off the 16 mm rod or guide the part separately over the longer travel.
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 MARF63X75S FAQ
Rated push is 1557.9 N and pull 1457.4 N at 0.5 MPa; at 0.7 MPa expect 2181.0 N and 2040.3 N. The 1.0 MPa theoretical ceiling is 317.7 kgf. Supply 0.15-1.0 MPa (22-145 psi) of 40 um filtered air and run 30-800 mm/s.
Two needle screws at the covers meter exhaust at each stroke end. Turn them in to soften arrival for heavy loads or fast cycles; the cushion is variable rather than fixed, so a 75 mm stroke can be retuned whenever speed or load changes.
