Airtac MAC Stainless Steel Mini Air Cylinder MAC40X150SUFA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X150SUFA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MAC40X150SUFA
For vertical work the 628 N push of a 40 mm bore equals about 64 kg, or a comfortable 32 kg with a 2:1 margin - and MAC40X150SUFA adds an FA flange so the cylinder bolts square to plates and fixtures without foot brackets. The round stainless barrel with a hard-chrome plated 12 mm rod resists the corrosion that quietly kills painted minis in wet or dusty halls.
It is double acting with variable air cushions at both ends, running 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) air. Open the cushion needles partway on the first stroke and tune until the load settles quietly. At 0.7 MPa the same bore reaches 880 N push; keep continuous loads near 377 N at 0.5 MPa and the grease-storing piston seal will hold up over the long haul. CMSG, DMSG and EMSG switches drop onto the standard magnet.

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 MAC40X150SUFA Is Used
Bearing Press Fit
Presses small bearings into pump housings at a bench station; the FA flange holds the cylinder square to the press tool for straight, bind-free insertion.
Casting Pick-Up Lift
Raises a 30 kg aluminium casting off a fixture on a lift-assist arm; the 2:1 vertical margin of this 40 mm bore keeps the lift smooth even as line pressure dips.
Reject Diverter Pusher
Deflects rejected bottles off a filler conveyor into a bin; 880 N at 0.7 MPa swings the diverter fast while both cushions kill the end-of-travel bang.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X150SUFA the Right Cylinder?
Compare against neighbours: 32 mm gives 402 N push at 0.5 MPa and 50 mm gives 981 N, so this 40 mm flanged unit covers loads between roughly 240 and 600 N. The FA flange suits perpendicular face mounting on fixtures; for base or pivoting fixes choose an LB foot or SDB pivot instead. Air loss means rod movement on any plain MAC - fit a rod lock where a raised load must stay up. 1/8" ports, PT as standard with G and NPT options.
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 MAC40X150SUFA FAQ
Push 628 N, pull 528 N at 0.5 MPa; push 880 N, pull 739 N at 0.7 MPa; 128.1 kgf theoretical maximum at 1.0 MPa. Operating range 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
An FA flange clamps the cylinder perpendicular to a flat surface, keeping the 12 mm rod aligned on straight push and lift jobs. If the mount must swing, pick an SDB pivot or the CA back-cover version instead - and all MAC sizes carry the standard magnet for CMSG, DMSG and EMSG sensing.
