Airtac MARU Stainless Steel Mini Cylinder MARU25X600S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU25X600S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø25mm bore and 600mm 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 MARU25X600S
A 25 mm bore MAR stretched to a 600 mm stroke, double acting with adjustable air cushions at both ends and an upward-facing front bracket rolled into the body. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; keep to about 147 N of usable work and the cylinder runs with margin rather than at its ceiling.
The 600 mm travel goes past the 500 mm catalogue maximum for this bore, so AirTAC builds it to order on the same riveted stainless tube and hard-chromed 10 mm rod. Over such a span the rod needs external guidance if the load hangs off-axis. The piston magnet is fitted as standard, so CMSG, DMSG and EMSG switches clip on for end-of-travel detection.

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 MARU25X600S Is Used
Carton Pusher on a Wide Conveyor
A 600 mm reach sweeps a pusher across the full belt width; cushioned stops keep the 245.3 N stroke from hammering the frame at each end.
Gate Drop Between Sorter Lanes
Drops a divert gate 600 mm into the product path, with the standard magnet flipping a CMSG switch at both stroke ends.
Belt Tensioner Take-Up
Long travel suits a take-up carriage holding about 147 N of steady tension on a slow-moving conveyor belt.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU25X600S the Right Cylinder?
At this force class you could step down to a 20 mm bore (157 N push at 0.5 MPa) for light pick-and-place, or up to a 32 mm bore (402.2 N) once the load nears 150 N of real resistance. The integrated top bracket bolts the cylinder straight to a machine plate; no separate foot or flange is needed. Remember that a standard MA piston drifts when supply pressure drops, so add a rod lock if a mid-stroke stop must survive air loss.
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 MARU25X600S FAQ
At 0.5 MPa the bore 25 barrel pushes 245.3 N and pulls 206.1 N; at 0.7 MPa that rises to 343.4 N push and 288.5 N pull. Theoretical maximum force is 50 kgf at 1.0 MPa (145 psi). The 600 mm stroke is a made-to-order length, above the 500 mm standard for this bore.
Needle screws at both heads meter exhaust air, so you can soften end-of-stroke impact during commissioning and run faster afterwards. Because every MA-series cylinder ships with the piston magnet already installed, CMSG, DMSG and EMSG switches simply clip onto the 25 mm stainless barrel for position signals.
