Airtac MAC Stainless Steel Mini Air Cylinder MAC40X170SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X170SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 170mm 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 MAC40X170SCA
The 40 mm bore of the MAC40X170SCA turns 0.5 MPa shop air into 628 N of push and 528 N of pull, double acting, while a variable air cushion at each end soaks up the shock of a 170 mm stroke. Its body is a stainless-steel barrel rolled and riveted onto aluminium-alloy covers with a stainless block, so the round tube shrugs off washdown and damp plant air that blisters painted-steel minis.
Working pressure spans 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi) and speeds of 30-800 mm/s. The piston magnet is standard, so CMSG, DMSG or EMSG switches clip on without a special order. Size on roughly 377 N of usable force at 0.5 MPa - about 60% of rated push - which indexes or clamps a 30 kg class part with real margin.

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 MAC40X170SCA Is Used
CNC fixture clamp
628 N of push at 0.5 MPa clamps steel or aluminium blanks in a machining fixture, with the 170 mm stroke clearing the loader arm between cycles.
Tray ejector
Kicks filled trays off a packaging infeed at up to 800 mm/s, and the end cushions stop the tray without hammering the covers.
Conveyor divert gate
Swings a divert gate on the CA pivot pin, pushing product off a belt line while the magnet-driven EMSG switch confirms gate position.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X170SCA the Right Cylinder?
Drop to the 32 mm bore (402 N push at 0.5 MPa) for lighter clamps, or step up to the 50 mm bore (981 N) when the job outgrows 40 mm. Over a 170 mm stroke keep the load guided externally; side loads at the rod shorten seal life. Air ports are 1/8" and the rod thread is M12x1.25. The CA pivot back cover swings on a pin - pair it with SDB pivot brackets or I / Y rod knuckles for rotating linkages, or FA flange / LB foot brackets for fixed mounting. Note the rod drifts the moment air drops or the valve centres; the cushion is not a lock, so fit a rod lock or pilot check valve if the load has to stay put.
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 MAC40X170SCA FAQ
At 0.5 MPa the cylinder pushes 628 N and pulls 528 N; at 0.7 MPa push rises to 880 N and pull to 739 N, with a theoretical maximum of about 128.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s.
It adds a pivoting joint at the rear cover, so the cylinder can follow a swinging linkage without extra brackets. Combine it with SDB pivot brackets, FA flange or LB foot mounts, and I or Y rod knuckles at the front. The bore-40 port is 1/8" and the male rod thread is M12x1.25.
