Airtac MAC Stainless Steel Mini Air Cylinder MAC16X250SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC16X250SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø16mm bore and 250mm stroke, M5×0.8 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 MAC16X250SCM
The CM round-end back cover on the MAC16X250SCM gives assemblers a clean pivot point that sits inside a matching clevis or U-bracket, on a barrel spanning 250 mm of stroke at just 16 mm bore. Double-acting operation means air pushes the rod out and pulls it back, with a variable cushion at each end to soften arrival. At 0.5 MPa the piston delivers 100.5 N of push and 86.4 N of pull; raise supply to 0.7 MPa and push reaches 140.7 N.
The body is a stainless tube with rolled-on aluminium covers and a hard-chrome plated rod, a combination that tolerates washdown and outdoor dust where coated minis fail. Count on close to 60 N of practical push at 0.5 MPa - call it a 5 kg vertical lift with a 2:1 margin. The built-in magnet needs no ordering decision: CMSG, DMSG and EMSG switches fit straight from the box.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAC16X250SCM Is Used
Craft brewery cap press
Above the filler bowl of a small brewery line, the cylinder presses crowns onto bottles with a cushioned final approach.
Pill counter lane divider
A rotating divider blade on a pill counting machine changes lane, driven by the 250 mm rod travel between two sensor stops.
Label unwind tension arm
The cylinder counterbalances the tension arm of a label unwind stand, easing web tension changes without hand adjustment.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC16X250SCM the Right Cylinder?
Thrust scales with bore: if 100.5 N of push at 0.5 MPa leaves no margin, the next size up, MAC20X250, returns 157 N, and a MAC25X250 reaches 245.3 N. Run the cylinder on 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi). Remember the rod is free to move whenever supply pressure drops or the valve sits mid-position; a pilot check valve or rod lock holds the load instead. Mounting flexibility covers FA flange, LB foot and SDB pivot brackets plus I or Y rod knuckles, with M5x0.8 ports and an M6x1.0 rod thread.
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 MAC16X250SCM FAQ
Push force is 100.5 N and pull force 86.4 N at 0.5 MPa; at 0.7 MPa you get 140.7 N push and 120.9 N pull. Theoretical maximum for the bore is 20.5 kgf at 1.0 MPa. Air ports are M5x0.8, rod thread is M6x1.0 on the 6 mm rod, and stroke speed runs 30-800 mm/s.
The round end is made to ride in a clevis or pivot bracket for swinging linkages. Where a fixed mount is preferred, add the FA flange, LB foot or SDB pivot bracket, and use an I or Y rod knuckle on the M6x1.0 thread to connect the load.
