Airtac MARU Stainless Steel Mini Cylinder MARU32X450S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X450S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 450mm 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 MARU32X450S
A long-travel 32 mm bore mini cylinder built for top-flange mounting: the MARU32X450S is double acting with a variable cushion at both ends and carries its own U front bracket, so it bolts straight to the machine with no separate foot. Fed with air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), it delivers a 402 N push and a 346 N pull at 0.5 MPa.
The stainless round barrel and hard-chrome plated rod shrug off washdown and damp air far better than painted mini bodies, and the riveted covers keep the seal tight over the full 450 mm travel. Air cushions at each end soak up end-of-stroke shock, so faster cycles do not hammer the covers. Working the numbers: budget roughly 241 N of real push at 0.5 MPa instead of the full 402 N rating, and expect about 20 kg of vertical lift on 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 (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 MARU32X450S Is Used
Carton push-off at line end
Sweeps full or rejected cartons off a roller conveyor across a 450 mm arc; 402 N at 0.5 MPa slides 15-20 kg boxes without straining the stroke.
Tray lift between shelf levels
Vertical column in a tray stacker: with roughly 20 kg of vertical lift on a 2:1 margin, it raises loaded trays from one shelf to the next.
Sliding gate on a filler
Divides bottle lanes on a packaging filler; the 450 mm travel spans two lane widths and the adjustable cushions let the gate run fast without slamming.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X450S the Right Cylinder?
Size it against neighbours: a 25 mm bore MAR gives 245 N at 0.5 MPa while a 40 mm bore reaches 628 N, so this 32 mm unit is the balanced middle pick for 450 mm travel. A plain MAR drifts if air is lost - the cushion only softens the stroke end - so add a rod lock where a mid-stroke hold matters. The built-in magnet pairs with CMSG / DMSG / EMSG switches out of the box. At 450 mm of stroke, guide the load externally and keep side loads low; the 12 mm rod is not meant to carry bending. Air ports are 1/8 in. and the rod thread is M10x1.25.
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 MARU32X450S FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N. At 0.7 MPa the push climbs to 563 N. The theoretical maximum is 82 kgf at 1.0 MPa. The 450 mm stroke sits on a 32 mm bore with 1/8 in. air ports and a 12 mm rod.
Yes. The body is a riveted stainless-steel round tube with a hard-chrome plated rod, which resists mild corrosion and washdown far better than painted minis. Variable cushion needle screws sit at both ends, and the approved speed range is 30-800 mm/s.
