Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SCASDB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SCASDB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MAC40X100SCASDB
Supplied with an SDB pivot bracket already fitted, the MAC40X100SCASDB swings on a clevis pin with no extra hardware, converting its 628 N push at 0.5 MPa into smooth pivoting motion. The 40 mm bore drives a 100 mm stroke, and a variable air cushion at both ends keeps landings controlled across the full 30-800 mm/s range.
Inside sits the familiar MAC recipe of riveted stainless barrel, hard-chrome plated rod and grease-storing piston seals, so humid and washed-down surroundings cause little trouble. The built-in magnet is standard, pairing with CMSG, DMSG or EMSG switches for position feedback. Treat roughly 377 N as the practical push at 0.5 MPa, which lifts about 32 kg vertically with a 2:1 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 MAC40X100SCASDB Is Used
Swinging stopper arm
Swings a stopper into the path of pallets on a roller conveyor, pivoting on the supplied SDB bracket.
Tilting discharge flap
Tilts a discharge flap on a washdown hopper, where the stainless barrel handles daily hose-down cycles.
Case squaring pusher
Squares carton stacks before strapping on a case packer, with the air cushion quieting each high-speed landing.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC40X100SCASDB the Right Cylinder?
Lighter work suits the 32 mm bore at 402 N; the 50 mm bore, pushing 981 N at 0.5 MPa, covers heavier duty. With no internal spring or lock, the rod cannot hold a load once air is lost, so add a pilot check valve or rod lock for anything suspended. Pair the SDB bracket with a CA pivot, U flat-end or CM round-end back cover to suit the frame, and guide side loads externally to spare the 16 mm rod.
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 MAC40X100SCASDB FAQ
At 0.5 MPa it produces 628 N push and 528 N pull; at 0.7 MPa, 880 N push and 739 N pull, with a theoretical ceiling near 128 kgf at 1.0 MPa. Supply 40 um filtered air to the 1/8 in ports at 0.15-1.0 MPa (22-145 psi) and cycle at 30-800 mm/s.
It adds a pivot: the bracket lets the whole cylinder swing about a pin, ideal for tilting flaps and swinging arms. You can still specify CA pivot, U flat-end or CM round-end back covers, and add FA flange or LB foot mounts where a fixed anchor is preferable.
