Airtac MARU Stainless Steel Mini Cylinder MARU40X700S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU40X700S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø40mm bore and 700mm 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 MARU40X700S
Long-travel work is where the MARU40X700S earns its place: a made-to-order 700 mm stroke - past the 500 mm catalog limit for this bore - on a 40 mm stainless round barrel, double-acting, with an adjustable air cushion at each end and an up bracket formed into the front cover. Push at 0.5 MPa is 628 N, with 528 N on the return stroke.
Plan around 377 N of usable thrust at 0.5 MPa, equivalent to holding about 64 kg vertically or 32 kg with a 2:1 factor. Over a 700 mm span the 16 mm hard-chrome rod is the member to protect, so carry the load on external linear guides and keep side forces off the rod; the riveted stainless barrel meanwhile shrugs off the corrosion that wrecks painted minis in wet plants.

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 MARU40X700S Is Used
Paint booth door drive
The 700 mm made-to-order travel slides a spray-booth access door across its full width; external guides carry the weight while the rod contributes its 377 N of working push.
Spray gantry lift
Raising a paint-gun gantry near 32 kg with margin fits the 628 N bore class, and the cushion eases the top-of-travel stop so the frame never hammers.
Scrap chute actuator
Under a stamping press, the long stroke tips a gravity-assisted scrap chute; 377 N of working force at 0.5 MPa is ample for the flap and linkage.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU40X700S the Right Cylinder?
Check whether a smaller bore does the job first: the 32 mm MAR moves carriages with 402 N at 0.5 MPa and saves air over a 700 mm stroke, while the 50 mm MAR at 981 N suits loads approaching the half-kilonewton class. MAC, MACD and MACJ cylinders exist if you ever prefer a separate flange or foot arrangement instead of the MAR's built-in up bracket. Because mid-stroke holding is impossible without air - the cushion is not a brake - pair a rod lock with the M12x1.25 rod when the door or gantry must stay parked. Air feeds through a 1/8" port.
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 MARU40X700S FAQ
Push at 0.5 MPa is 628.3 N and pull is 527.8 N; at 0.7 MPa these become 879.6 N and 738.9 N; the theoretical maximum at 1.0 MPa is 128.1 kgf. The 700 mm stroke is made to order, ports are 1/8", the rod is 16 mm with M12x1.25 thread, pressure 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof.
The needle-adjusted cushions at both ends absorb end-of-travel shock, but they do nothing against lateral force. Mount the load on an external linear guide, square the integrated up bracket to the travel direction, and stay within 30-800 mm/s; the 16 mm hard-chrome rod then reaches its full service life.
