Airtac MARU Stainless Steel Mini Cylinder MARU25X200S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X200S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 200mm 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 MARU25X200S
Two hundred millimetres of stroke from a riveted stainless mini - the MARU25X200S covers long-reach points on compact machines where a full-size cylinder will not fit. It is double acting, cushioned variably at each end, and carries its own top (U) bracket on the front cover, so mounting needs no separate flange or foot. Supply air at 0.15-1.0 MPa (22-145 psi).
The 25 mm bore makes 245 N on extension and 206 N on retraction at 0.5 MPa; at 0.7 MPa extension reaches 343 N. Practical sizing: plan around 147 N of working force at 0.5 MPa, which lifts roughly 12 kg vertically with a 2:1 margin - handy when you are balancing a probe arm or a light gantry axis over a 200 mm travel. The built-in magnet (standard) lets a DMSG switch report end positions, and the stainless barrel plus hard-chrome rod handle washdown corners that pit painted minis.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MARU25X200S Is Used
Lift stage on an optical inspection station
Raises a camera head 200 mm between two inspection heights; about 12 kg of derated vertical lift at 0.5 MPa carries the head with margin, and cushions land it without jitter.
Bin pick arm on a tote handling cell
Reaches into a 400 mm deep tote to present parts to a gripper; 245 N of push at 0.5 MPa seats the arm while external bushings take any side load.
Tensioner on a wire spooler
Keeps a guide roller bearing on wire at a set tension; 206 N of pull at 0.5 MPa lets you tune pressure down for fine control over the 200 mm travel.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X200S the Right Cylinder?
At 200 mm this is one of the longer standard strokes in the 25 mm class (the MA series takes this bore to 500 mm), so side loads matter: keep the load guided on rails or a bushing and let the 10 mm rod see thrust only. If 245 N at 0.5 MPa feels light, a 32 mm bore gives 402 N at the same pressure; if you are over-specifying, the 20 mm bore still makes 157 N. The cylinder will not hold a load against air loss - it drifts, so use a rod lock where a stopped position must be kept. Sensor match: CMSG, DMSG and EMSG switches all fit the standard magnet; 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 MARU25X200S FAQ
At 0.5 MPa: 245.3 N push, 206.1 N pull. At 0.7 MPa: 343.4 N push, 288.5 N pull. Theoretical maximum 50 kgf at 1.0 MPa. Operating window 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
Long strokes build momentum, so the adjustable needle screws at each end let you bleed the last few millimetres of air and land the rod gently at any speed up to 800 mm/s. Turn them in on first run until the ends stop knocking - it protects the aluminium covers and your load.
