Airtac MAC Stainless Steel Mini Air Cylinder MAC40X160SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X160SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MAC40X160SCM
Round-end CM back cover on a 160 mm stroke gives the MAC40X160SCM a clean pivot point for linkages and bell cranks. In the 40 mm bore it develops 628 N of push and 528 N of pull at 0.5 MPa, rising to 880 N at 0.7 MPa, as a double-acting cylinder with adjustable air cushion on both ends.
AirTAC rolls the stainless barrel into the aluminium covers, a riveted construction that shrugs off washdown better than painted-steel minis in food and packaging lines. Working at 0.5 MPa, budget roughly 377 N for the actual task rather than the full 628 N figure - that margin keeps acceleration smooth across 160 mm of travel at up to 800 mm/s.

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 MAC40X160SCM Is Used
Pusher on belt line
Kicks cartons sideways at a 90 degree transfer on a packaging belt; 628 N at 0.5 MPa moves 8 kg cases well inside the 160 mm window.
Damper linkage drive
Drives a bell crank that modulates an oven air damper; the CM round-end pivot tracks the crank arc while cushions settle each reversal.
Battery lockout pin
Slides a lockout pin into a forklift charging station; a DMSG switch on the built-in magnet proves the pin is engaged before charging starts.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X160SCM the Right Cylinder?
Against the 40 mm bore's 628 N at 0.5 MPa, the 25 mm MAC (245 N) suits lighter gate work while the 63 mm bore (1558 N) handles die changes; both share this same round-body platform. The CM round-end cover pivots on a pin through the cover boss - pair it with an FA flange or LB foot when the body must be fixed too. Because air pressure alone positions the rod, a centred valve lets the load drift; specify a rod lock where the position must stay. Ports are 1/8" on this bore.
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 MAC40X160SCM FAQ
Push 628.3 N and pull 527.8 N at 0.5 MPa; push 879.6 N and pull 738.9 N at 0.7 MPa; theoretical maximum about 128.1 kgf at 1.0 MPa. Stroke is 160 mm, speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi).
Both ends carry a variable cushion. Before first run, open the needle screws fully, then close them a little at a time until the load lands quietly. This protects the covers when cycling heavy linkage loads near the 800 mm/s top speed.
