Airtac MARU Stainless Steel Mini Cylinder MARU20X95S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU20X95S is a genuine double acting + cushion (up mount) 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 MARU Stainless Steel Mini Cylinder MARU20X95S
Long light strokes are where the MARU20X95S earns its slot: a 95 mm reach on the smallest 20 mm MAR bore, in a riveted stainless round body with double-acting air and a variable cushion at each end. The front cover integrates its own top (U) mounting bracket, so the cylinder is screwed to the machine directly; no separate flange or foot accessory exists in this design. A piston magnet is fitted as standard for CMSG, DMSG and EMSG switches.
At 0.5 MPa the rod extends with 157 N and retracts with 132 N; at 0.7 MPa the push climbs to 220 N, and 32 kgf is the 1.0 MPa theoretical peak. That 157 N equals roughly 16 kg of raw push, so figure on about 8 kg of vertical lifting once a 2:1 margin is applied. The stainless tube and hard-chrome plated rod hold up in splash zones and outdoor cabinets while running 30-800 mm/s on 0.15-1.0 MPa (22-145 psi).

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 MARU Stainless Steel Mini Cylinder MARU20X95S Is Used
Film splice press
Presses the splice bar on a film unwinder, where the 95 mm stroke reaches over the roll and the cushion stops the bar without a bang.
Lane divider
Swings a divider between conveyor lanes in a warehouse pick module, confirmed end to end by DMSG switches on the barrel.
Cabinet door actuator
Nudges open a slide door on an outdoor electrical cabinet, where the stainless body ignores rain and the 8 kg lift class suits the light panel.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU20X95S the Right Cylinder?
Since 20 mm is the smallest MAR bore, the sizing decision is upward: choose the 25 mm bore with its 245 N push at 0.5 MPa when the load creeps past roughly 94 N of real work. Remember this cylinder coasts free if the air supply fails, so it is not a position lock; pair it with a rod lock where holding matters. At 95 mm of stroke, keep side loads on an external guide, while the 1/8" ports and M8x1.25 rod thread stay the same across the small bores.
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 MARU Stainless Steel Mini Cylinder MARU20X95S FAQ
It produces 157 N push and 132 N pull at 0.5 MPa, 220 N push and 185 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa. It uses 1/8" ports, an 8 mm rod with M8x1.25 male thread, and runs 30-800 mm/s.
It means the top/up mounting bracket is built into the front cover of the cylinder itself. You bolt the MAR straight to your plate or frame; no separate front flange or foot accessory is used with this series. I and Y rod knuckles can still be fitted to the rod end if the load needs a swivel.
