Airtac MARU Stainless Steel Mini Cylinder MARU32X270S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X270S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 270mm 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 MARU32X270S
Spanning 270 mm, the MARU32X270S is the long-reach option in AirTAC's 32 mm bore MA minis: a stainless round barrel rolled up with aluminium covers into a riveted, sealed body, running a hard-chrome plated 12 mm rod. Air drives it both ways - double acting - with a variable cushion at each end, and the U in the code means a top mounting bracket is built onto the front cover, so no separate flange or foot is bought or aligned.
At 0.5 MPa (about 72 psi) this bore pushes 402.2 N and pulls 345.6 N; near 0.7 MPa (about 102 psi) those figures rise to 563.0 N and 483.8 N, peaking at a theoretical 82 kgf at 1.0 MPa. In practice, size jobs at about 241 N of push; as a vertical yardstick, the full 402.2 N equates to roughly 41 kg of lift, or about 20 kg once a 2:1 margin is kept. The piston magnet is fitted as standard, so CMSG, DMSG or EMSG switches clip on for position sensing. Supply runs 0.15-1.0 MPa (22-145 psi) at 30-800 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MARU32X270S Is Used
Long-throw gating on bottling lines
Divert bottles between lanes with a 270 mm sweep; 402 N push at 0.5 MPa handles jammed containers without stalling.
Electronics pick and place Z-axis
Lifts a 15 kg PCB magazine carrier vertically with a 2:1 margin, cushion ends softening each 270 mm cycle.
Lab furnace door actuation
Stainless barrel and chrome rod shrug off warm, humid oven exhaust on a 270 mm sliding furnace lid.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X270S the Right Cylinder?
Sizing check: a 25 mm MAR at the same pressure delivers 245.3 N push at 0.5 MPa - fine for light gates - while stepping up to 40 mm buys 628.3 N. If your load at 0.5 MPa exceeds about 241 N, go 40 mm rather than trusting the full 402.2 N rating. Note the MAR drifts if air is lost; it cushions the ends but does not lock, so add a rod lock for a load that must hang. Over 270 mm of travel, keep side load off the 12 mm rod and guide the part externally - long strokes punish misalignment. The integrated top bracket bolts the body straight to the machine plate; the standard magnet lets a CMSG or DMSG switch read position anywhere along the tube.
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 MARU32X270S FAQ
At 0.5 MPa (about 72 psi) it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa (about 102 psi) those rise to 563.0 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) and piston speed runs 30-800 mm/s.
No - every MA-series cylinder ships with a piston magnet already fitted, so AirTAC CMSG, DMSG and EMSG switches mount directly on the 32 mm tube for end-of-stroke or mid-stroke detection.
