Airtac MARU Stainless Steel Mini Cylinder MARU40X65S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU40X65S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø40mm bore and 65mm 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 MARU40X65S
Double-acting and cushioned at both stroke ends, the MARU40X65S is a 40 mm mini cylinder on a stainless round barrel whose aluminium-alloy covers are rolled into place, and whose up-mount bracket is part of the body itself - no separate flange or foot to buy. At 0.5 MPa it pushes 628 N and retracts with 528 N across a 65 mm stroke, with speed tunable from 30 to 800 mm/s.
Read the rating honestly: about 377 N of that 628 N push is sensible continuous working force at 0.5 MPa, which lifts roughly 64 kg vertically - or 32 kg with a 2:1 margin. The hard-chrome plated 16 mm rod and rolled stainless barrel outlast painted mini bodies in damp or washed-down corners, and the standard magnet accepts CMSG, DMSG and EMSG switches as shipped.

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 MARU Stainless Steel Mini Cylinder MARU40X65S Is Used
Tray ejection on bakery lines
A 65 mm kick with 377 N of usable thrust slides trays off the discharge conveyor cleanly, while the adjustable end cushion removes the bang at each stop.
Indexing weld fixtures
Vertical duty suits the up bracket: the rod handles about 64 kg, so a 30 kg welding fixture indexes upward with a comfortable 2:1 margin.
Bench clamping of pump covers
Holding force around 377 N at 0.5 MPa clamps aluminium pump covers while gasket adhesive cures; the stainless barrel ignores the coolant mist around the bench.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU40X65S the Right Cylinder?
Work the numbers both ways before ordering: the 32 mm MAR pushes 402 N at 0.5 MPa and the 50 mm MAR pushes 981 N, so the 40 mm bore is the right middle step when your load sits between roughly 240 and 590 N of usable force. A plain MAR will drift if air pressure drops - the cushion only softens the stroke ends - so add a rod lock where a held position must survive power loss. The 1/8" port, 16 mm rod and M12x1.25 male thread carry the usual I and Y knuckles, and the magnet is already inside for CMSG, DMSG or EMSG switches.
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 MARU40X65S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa, 879.6 N and 738.9 N; the theoretical maximum at 1.0 MPa is 128.1 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, speed 30-800 mm/s, 1/8" ports, and a 16 mm rod with M12x1.25 male thread.
No. The U bracket is rolled into the front cover as part of the body, so no separate flange or foot is fitted - though I and Y rod knuckles still attach to the rod thread. The built-in magnet is standard, so CMSG, DMSG or EMSG switches mount without a special piston.
