Airtac MAC Stainless Steel Mini Air Cylinder MAC40X175SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X175SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MAC40X175SCA
A stainless-steel barrel rolled onto aluminium covers, a hard-chrome plated 16 mm carbon-steel rod and grease-retaining heterogeneous piston seals give the MAC40X175SCA a build that survives humid, washed-down corners of the plant where painted minis corrode. The 40 mm bore runs double acting, pushing 628 N and pulling 528 N at 0.5 MPa over a 175 mm stroke.
Both ends carry a variable air cushion you can tune with the needle screws, so faster strokes or heavier loads arrive softly. Open the needles on first run and dial them in gradually. As a rule of thumb the 628 N push at 0.5 MPa lifts about 64 kg vertically, or about 32 kg if you keep a 2:1 margin for the real part weight.

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 MAC40X175SCA Is Used
Bench-top bushing press
A small press station that seats bushings in housings, using 628 N at 0.5 MPa and the 175 mm stroke to reach inside a deep fixture.
Rinse-head lift in a washdown zone
The stainless barrel and chrome rod shrug off daily hose-down while the cylinder lowers a rinse head 175 mm into a wash tank.
Vacuum-cup vertical lift
With about 32 kg of vertical capacity at a 2:1 margin, a suction gripper picks cartons off a pallet and sets them on the infeed.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X175SCA the Right Cylinder?
The 32 mm MAC gives 402 N at 0.5 MPa and the 50 mm bore 981 N, so 40 mm sits in the middle of the range. Magnet is standard - CMSG, DMSG and EMSG switches mount without a special piston. Thread options are PT (blank code), G or NPT. Long strokes like 175 mm punish side loads, so guide the payload on its own slides and let the rod see pure axial force. This is an air-driven cylinder, not a holding device: when pressure drops the rod floats, and only a rod lock or pilot check valve will keep a suspended load in position.
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 MAC40X175SCA FAQ
Push is 628 N and pull 528 N at 0.5 MPa; at 0.7 MPa the cylinder delivers 880 N push and 739 N pull, peaking around 128.1 kgf theoretical at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof, and cycles at 30-800 mm/s.
Needle screws at both covers meter the exhaust to create an adjustable air cushion. Back them fully off at commissioning, then close gradually until end-of-stroke shock disappears - useful when cycling at the top of the 30-800 mm/s range or decelerating a heavy load.
