Airtac MAC Stainless Steel Mini Air Cylinder MAC40X130SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X130SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 130mm 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 MAC40X130SCA
Swing links and pivoting levers suit the MAC40X130SCA: a 40 mm bore, 130 mm stroke, double acting mini cylinder whose CA pivot back cover takes a clevis pin directly. The variable air cushion at both ends is adjusted with needle screws, letting you decelerate heavy or fast-moving loads gently across the 30-800 mm/s band. At 0.5 MPa expect 628.3 N of push and 527.8 N of pull; the stainless round barrel and hard-chrome rod stand up to mild corrosion and washdown in food or damp plants.
A useful planning figure: about 377 N of real work at 0.5 MPa (60% of the rated push) keeps the cylinder healthy long term. Vertical-lift wise it can raise close to 64 kg, so size for roughly 32 kg with a 2:1 margin. The magnet comes built in, so CMSG, DMSG and EMSG switches fit with no special-order piston.

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 MAC40X130SCA Is Used
Swing-arm diverter
Drives a swing-arm that flips parts between two conveyor lanes; the CA pivot back cover takes the clevis pin with no extra bracket.
Wash tank lid opener
Swings lids open on wash tanks in a washdown food plant - the riveted stainless body tolerates daily hose-down where painted minis would corrode.
High-cycle sorter
Runs a sorting finger at 30-800 mm/s for thousands of cycles per shift, cushioning both ends so the machine frame stays quiet.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X130SCA the Right Cylinder?
A 130 mm stroke in a 40 mm bore is moderate, but keep side loads off the rod - guide the load externally or use a Y or I knuckle - or the hard-chrome rod and bearings wear early. Compared with the 32 mm bore (402.2 N push at 0.5 MPa) this gives 628.3 N; the 50 mm bore reaches 981.3 N if you need more. The CA pivot back cover accepts clevis pins directly, and LB foot or FA flange brackets add fixed mounting; if the load must hold with air off, add a rod lock or pilot check valve, because the MAC alone will drift.
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 MAC40X130SCA FAQ
Push 628.3 N and pull 527.8 N at 0.5 MPa, rising to 879.6 N push and 738.9 N pull at 0.7 MPa; theoretical maximum 128.1 kgf at 1.0 MPa. The 40 mm bore takes 1/8" ports and a 16 mm rod threaded M12x1.25, with an operating range of 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s speed.
The CA cover takes a clevis pin directly for swinging or pivoting motion; add an FA flange, LB foot or SDB pivot bracket if the body also needs fixing, and I or Y rod knuckles at the working end. That keeps a swing-arm build down to the cylinder plus one bracket.
