Airtac MAC Stainless Steel Mini Air Cylinder MAC40X90SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X90SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 90mm 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 MAC40X90SCA
For a 90 mm stroke of pushing and pulling, MAC40X90SCA delivers 628 N forward and 528 N back at 0.5 MPa within the 0.15-1.0 MPa (22-145 psi) supply band. Vertically that is roughly 64 kg of lift at full pressure - halve it for a 2:1 margin and it raises about 32 kg of real payload, handy for lid or fixture work. The variable cushion at each end dials out impact so the covers last.
AirTAC rolls the aluminium covers and a stainless block onto the steel barrel, a sealed riveted joint that keeps the round body rigid without external hardware, so it survives damp plants far better than painted minis. The CA pivot back cover swings on a pin without extra brackets, and the built-in magnet means position switches (CMSG / DMSG / EMSG) mount straight on.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAC40X90SCA Is Used
Carton lane switch
Pivot pin mount flips cartons at a sorter junction; the cushioned stop keeps the flap from slamming even at 800 mm/s.
Brewery tank lid lift
Raises about 32 kg of stainless hatch with a 2:1 margin; the sealed riveted barrel copes with daily hose-down.
Clutch yoke actuator
628 N forward engages the yoke and 528 N pull releases it; the magnet signals engaged position via a CMSG switch.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X90SCA the Right Cylinder?
Size by force: a 32 mm MAC pushes 402 N at 0.5 MPa while the next size up, 50 mm, reaches 981 N - this 40 mm model's 628 N covers the gap for gates and lifters. It does not hold position on lost air; the piston will drift, so fit a pilot check valve or rod lock where a suspended load matters.
CA pivot mounting swings freely on a pin, and the standard magnet works with CMSG / DMSG / EMSG switches for end-of-stroke signals. Air ports are 1/8"; rod thread M12x1.25 on a 16 mm 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 MAC40X90SCA FAQ
The piston magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight onto the 40 mm barrel and read end positions - no special-order piston required. Mount the CA pivot on a pin, add FA flange, LB foot or SDB brackets if the frame needs them, and plumb the 1/8" ports.
Push is 628.3 N and pull 527.8 N at 0.5 MPa; at 0.7 MPa those climb to 879.6 N and 738.9 N, with 128.1 kgf theoretical maximum at 1.0 MPa. Operating range 0.15-1.0 MPa (22-145 psi), rod 16 mm, rod thread M12x1.25, maximum standard stroke 500 mm.
