Airtac MAC Stainless Steel Mini Air Cylinder MAC32X45SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X45SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 45mm stroke, 1/8" 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 MAC32X45SCA
Short stroke, pivot mount, honest force: the MAC32X45SCA swings through 45 mm while pushing 402.2 N at 0.5 MPa, and the CA rear cover takes a pivot pin so the cylinder can follow an arc without extra hardware. Double acting throughout, it pulls back with 345.6 N at the same pressure, and both ends carry an adjustable air cushion to land the load quietly. Around 241 N is the figure to design around for continuous work, leaving the rating as reserve.
Build quality is where this mini earns its keep in wet or dusty plants: a stainless barrel rolled up with aluminium covers and a stainless block, plus a 20 um hard-chrome rod, resists the corrosion that kills painted minis. The 1/8" ports and 12 mm rod (M10x1.25 thread) suit compact manifolds, the magnet comes as standard for CMSG / DMSG / EMSG switches, and operating limits run 0.15-1.0 MPa (22-145 psi), -20 to +70 C.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAC32X45SCA Is Used
Chute flipper
Rocker arm flips rejected components off a vision-inspection chute the moment the camera flags them.
Sample tilt station
Tilts specimen racks on a lab analyser so used cuvettes slide into the waste drawer each cycle.
Index pin latch
Drops a rotary dial index pin into position every cycle, the cushioned landing keeping the dial from overshooting.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X45SCA the Right Cylinder?
Size against neighbours: the 25 mm bore gives 245.3 N push at 0.5 MPa and the 40 mm gives 628.3 N, so this 32 mm sits in the mid band for pivot linkages. A short 45 mm stroke tolerates modest side load far better than a long rod, but keep the pivot pin aligned all the same. If the mechanism must latch in place, note that an ordinary double acting cylinder lets the piston wander once air drops - a rod lock or pilot check valve is the fix. Alongside the CA rear cover, U and CM ends, FA flange, LB foot and SDB bracket are all available.
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 MAC32X45SCA FAQ
At 0.5 MPa: 402.2 N push and 345.6 N pull. At 0.7 MPa: 563.0 N push and 483.8 N pull. Theoretical maximum is 82 kgf at 1.0 MPa. Fluid is 40 um filtered air at 0.15-1.0 MPa (22-145 psi), with a 1.5 MPa (215 psi) proof rating.
Yes - every MAC cylinder carries a piston magnet as standard equipment, not a paid option. Clip a CMSG, DMSG or EMSG switch onto the 45 mm barrel and it senses end positions directly, with no special-order piston needed.
