Airtac MAC Stainless Steel Mini Air Cylinder MAC63X275SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X275SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 275mm 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 MAC Stainless Steel Mini Air Cylinder MAC63X275SCM
At the top of the MA force table, the MAC63X275SCM turns 0.5 MPa into 1557.9 N of push and 1457.4 N of pull over a 275 mm stroke, climbing to 2181 N at 0.7 MPa. It is double acting, with an adjustable air cushion at each end that decelerates the load instead of hammering the covers.
Its rolled stainless sleeve and 20 um hard-chrome rod tolerate wet, dusty and outdoor air far better than painted housings - no retorquing, no flaking paint around the ports. Translate the numbers for planning: close to 79 kg lifted vertically at half margin, or 935 N of realistic working push. The round-end CM back cover pins straight to a clevis, and the standard built-in magnet accepts CMSG / DMSG / EMSG switches with no special-order 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 (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 MAC Stainless Steel Mini Air Cylinder MAC63X275SCM Is Used
Tote lid clamp on fillers
Pulls a clamp arm down over washdown tote lids on a dairy filler; the stainless barrel and chrome rod shrug off the daily caustic rinse that ruins painted cylinders.
Seed hopper slide gate
Opens and closes a planter seed-hopper gate in the field; rain and fertilizer dust never reach the plated 16 mm rod inside the stainless sleeve.
Roll-cage wash door
Swings heavy mesh doors on warehouse roll-cage wash stations, with the CM round-end cover pinned straight to a clevis for the swing arc.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X275SCM the Right Cylinder?
If the job needs under 981 N at 0.5 MPa, the 50 mm bore is the thriftier pick; above roughly 900 N working load, this 63 mm cylinder is the ceiling of the series - no bigger bore exists. Air failure frees the rod instantly, so fit a pilot check valve or rod lock wherever the 275 mm travel must hold under load. The CM round-end cover takes clevis pins directly; LB foot and FA flange brackets, plus the SDB pivot, adapt it to any frame, and the rod thread is M14x1.5. Long strokes amplify misalignment - guide the load squarely to protect the 16 mm chrome rod.
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 MAC Stainless Steel Mini Air Cylinder MAC63X275SCM FAQ
Expect 1557.9 N push and 1457.4 N pull at 0.5 MPa, 2181 N and 2040 N at 0.7 MPa, and 317.7 kgf as the theoretical maximum at 1.0 MPa. Cycle it anywhere from 30-800 mm/s within the 0.15-1.0 MPa (22-145 psi) working band.
No - the magnet is built into the piston as standard on every MAC. CMSG, DMSG and EMSG switches clip onto the stainless barrel and sense end or mid positions immediately, with no special piston or retrofit needed.
