Airtac MAC Stainless Steel Mini Air Cylinder MAC20X95SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X95SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 95mm 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 MAC20X95SU
Air cushioning at each end makes the MAC20X95SU easy to live with on fast cycles: the needle screws let you dial out end-of-stroke shock, so a 95 mm stroke can run up to 800 mm/s without hammering the covers. The body is a rolled stainless round barrel with a hard-chrome carbon-steel rod, and the magnet is standard equipment ready for DMSG, CMSG or EMSG sensors.
The bore 20 chamber delivers 157 N forward and 131.9 N return at 0.5 MPa (22-145 psi), rising to 219.8 N at 0.7 MPa. In practice count on about 94 N of usable push, which corresponds to lifting roughly 8 kg vertically with a 2:1 safety 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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X95SU Is Used
Small-part ejector
Kicking stamped clips off a press die at the 95 mm mark; 157 N of push at 0.5 MPa is ample for light-gauge parts and the cushion protects the die face.
Belt diverter pin
Actuating a divert pin on a bakery packaging line - DMSG switches confirm each stroke and the chrome rod stands up to flour-dust washdown.
Dispenser hold-down
Pressing lids onto cosmetic jars during filling; roughly 8 kg of vertical capability with margin suits light hold-down cycles at 95 mm reach.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X95SU the Right Cylinder?
Bore 16 caps out at 100.5 N of push while bore 32 offers 402.2 N - the 157 N of this bore 20 unit sits between them for medium clamping and feed tasks. Porting is 1/8" on both caps and the male rod thread is M8x1.25. Because the plain MAC drifts when the valve centres or air drops, add a pilot check valve or rod lock wherever the load must stay put. The built-in magnet plus CMSG/DMSG/EMSG switches handles end-of-stroke signalling, and FA flange or LB foot mounts bolt straight on.
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 MAC20X95SU FAQ
Push at 0.5 MPa (22-145 psi) is 157 N, pull 131.9 N; at 0.7 MPa push is 219.8 N and pull 184.7 N. The theoretical ceiling at 1.0 MPa is 32 kgf. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um at 30-800 mm/s.
Yes. Back the cushion needle screws off before the first stroke, then close them gradually until end-of-stroke shock disappears at your cycle speed. The cushion is variable at both ends and works across the 30-800 mm/s speed band.
