Airtac MARF Stainless Steel Mini Air Cylinder MARF63X125S
The AirTAC Airtac MARF Stainless Steel Mini Air Cylinder MARF63X125S is a genuine double acting + cushion (front mount) standard round-body mini air cylinder with a Ø63mm bore and 125mm 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 MARF63X125S
Heavy thrust in a compact round body: the MARF63X125S delivers 1557.9 N pushing and 1457.4 N pulling at 0.5 MPa (72 psi) over a 125 mm stroke, double acting with adjustable air cushioning at both caps. Its stainless tube is rolled onto the aluminium covers, and the 16 mm piston rod carries a 20 um hard-chrome layer that shrugs off damp shop air.
The front flange is part of the cylinder, so it bolts to the machine plate with no separate mounting kit. Expect around 935 N of usable push at 0.5 MPa if you keep a 60% duty margin - about 79 kg of vertical lift with headroom. The standard-built magnet accepts CMSG or DMSG reed switches for stroke-end detection without special ordering.

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 MARF63X125S Is Used
Stamping die change lift
Lifts and seats small press dies during changeover on a 200 t press; the roughly 79 kg vertical lift capability with a 2:1 margin matches most die shoes.
Heavy cart pusher
Pushes wheeled steel carts onto a side spur in a warehouse; 1557.9 N at 0.5 MPa overcomes the rolling resistance of a fully loaded cart.
Case squaring press
Squares stacks of corrugated cases before strapping; the dual cushions stop the platen bang at the end of each 125 mm cycle.
Is the Airtac MARF Stainless Steel Mini Air Cylinder MARF63X125S the Right Cylinder?
Before settling on 63 mm, check whether a 50 mm bore (981.3 N push at 0.5 MPa) would do; MAR stops at 63 mm, so there is no larger option. On a 125 mm stroke keep side loads off the 16 mm rod with a guide or cam follower, or rod bending will show up early. Position is not held on air loss - the piston drifts - so a rod lock is the fix if you need one. The flange is integral; only rod knuckles bolt on separately.
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 MARF63X125S FAQ
This bore delivers 1557.9 N push and 1457.4 N pull at 0.5 MPa, climbing to 2181.0 N push and 2040.3 N pull at 0.7 MPa; the theoretical ceiling is 317.7 kgf at 1.0 MPa. For long life most engineers keep the working load near 60% of the 0.5 MPa push, about 935 N.
Needle screws in both end caps throttle the exhaust just before the piston seats, so you can soften the 125 mm stroke ends after installation. Turn them in for heavier loads or faster speeds; the working band is 30-800 mm/s overall. The cushion is adjustable, not a shock absorber, so extreme masses may still need external stopping.
