Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 65mm 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 MAC40X65SU
Flat mounting is the everyday case, and the U back cover answers it with a plain face for bolting. The MAC40X65SU delivers 628 N at 0.5 MPa over a 65 mm stroke, double acting, with needle-adjustable cushions trimming the stop at each end.
Because the barrel is stainless and the rod hard-chromed to 20 um, coolant mist and washdown will not flake coating into your product the way painted minis can. Set working demand near 377 N - the 60 percent figure - and this cylinder lifts roughly 32 kg vertically with a 2:1 margin in reserve. Switch detection comes without drama: the magnet is already in the piston for CMSG, DMSG and EMSG sensors.

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 MAC40X65SU Is Used
Reject kick-off
Rejected cartons are punched off the outfeed of a cartoning machine at line speed, the cushion softening every hit.
Slitter blade gap setting
Between runs the rod repositions the knife gap on a compact slitter, cushions letting it settle gently into place.
Bench bushing seat
A bench fixture eases bushings into housings using only a fraction of the 377 N working figure.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X65SU the Right Cylinder?
Compare 32 mm at 402 N and 50 mm at 981 N before locking in the 40 mm choice. Without air the rod moves freely, so a held load calls for a rod lock or check valve, never the cushion. Air ports are 1/8 in and the rod thread is M12x1.25. U flat end with FA flange or LB foot keeps fixtures rigid; SDB suits pivot base mounts, and CA or CM covers swap in where a link replaces the bolt.
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 MAC40X65SU FAQ
It pushes 628.3 N and pulls 527.8 N at 0.5 MPa; at 0.7 MPa push reaches 879.6 N and the theoretical maximum is 128.1 kgf at 1.0 MPa. As a guide, halving the 64 kg lift equivalent leaves about 32 kg vertical with margin.
Run it between 0.15-1.0 MPa (22-145 psi), proof-tested to 1.5 MPa (215 psi), on air filtered to 40 um. Rod speed from 30 to 800 mm/s is in range, and ambient temperatures from -20 to +70 C are fine.
