Airtac MAC Stainless Steel Mini Air Cylinder MAC32X270SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC32X270SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø32mm bore and 270mm 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 MAC32X270SCA
MAC32X270SCA stretches the 32 mm bore to a 270 mm stroke while keeping the CA pivot back cover for clevis-style mounting. Pushing 402.2 N at 0.5 MPa, it is the cylinder class for sliding guards, tray indexers and other long-travel moves in compact round-body form. The riveted stainless-steel barrel and chrome-plated carbon-steel rod stand up to washdown and humidity season after season.
Expect about 20 kg of vertical lift once a 2:1 margin is applied to the 41 kg theoretical figure - enough for lifting light lids and tooling plates. Variable air cushions at both caps let you soften the final millimetres of travel; open them fully at commissioning, then close gradually. The built-in magnet is standard, so CMSG switches clip on for end-of-stroke signalling.

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 MAC32X270SCA Is Used
Press brake guard door
Drives a sliding machine guard on a press brake cell; the 270 mm stroke clears full operator access while 402 N overcomes seal drag.
Tote lid lifter
Raises lids on 20 kg ingredient totes ahead of dosing; the roughly 20 kg vertical-lift budget keeps the duty inside its 2:1 margin.
Indexing table unlock
Pulls the locking pin of a rotary indexing table before each index; the CA pivot follows the linkage arc as the pin retracts.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC32X270SCA the Right Cylinder?
The 25 mm bore tops out at 245.3 N and the 40 mm bore delivers 628.3 N at 0.5 MPa, so this 32 mm model is the balance point at 402.2 N. For its 270 mm stroke, support long tooling so the 12 mm rod sees little bending moment. Remember the cylinder offers no position holding - air off means drift - so specify a rod lock or check valve where parking matters. The CA pivot cover plus an SDB bracket or FA flange keeps the mount rigid.
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 MAC32X270SCA FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa push climbs to 563.0 N, with a theoretical peak near 82 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, port 1/8 inch, and a 12 mm rod with M10x1.25 male thread.
The barrel is stainless steel rolled onto aluminium covers with a hard-chrome rod, so humidity and light washdown cause little trouble. Both caps carry variable air cushions adjusted by needle screws - open them fully at commissioning, then close until arrival shock disappears. The standard magnet pairs with CMSG, DMSG or EMSG switches.
