Airtac MARU Stainless Steel Mini Cylinder MARU40X160S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU40X160S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MARU40X160S
The 160 mm stroke makes the MARU40X160S a long-reach option in this bore class, moving clamps and gates across 160 mm while pushing 628 N at 0.5 MPa - 880 N once supply reaches 0.7 MPa. As a MAR, it is double acting with a variable air cushion at each end and an integrated up/top front bracket built into the front cover, so mounting is a single bolted face.
Realistic sizing: budget around 377 N for actual work at 0.5 MPa (60 percent of the 628 N rating), which will hoist roughly 32 kg against gravity with a 2:1 margin. The magnet is factory-fitted, so adding a DMSG or CMSG switch for end-of-stroke detection is a clip-on, not an order option.

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 MARU40X160S Is Used
Slide positioning in a fixture build
A 160 mm stroke indexes a machined part between two stations on a custom jig; 628 N of push at 0.5 MPa seats the part against its stop every cycle.
Reject pusher on a food grading line
The stainless barrel and chrome rod survive frequent hose-downs while the cylinder kicks off-spec produce off the grading belt; 32 kg vertical capability covers heavier crates too.
Formwork aligner on a precast line
Bolted via its top bracket to a steel frame, the 160 mm cylinder nudges precast panels into register; the two-end cushion prevents the panel from rebounding off the stop.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU40X160S the Right Cylinder?
If the job needs less muscle, the 32 mm bore and its 402 N push at 0.5 MPa save air and money; if it needs more, the 50 mm bore delivers 981 N. Be aware the piston coasts or sags whenever air pressure is removed - there is no internal lock - so pair the cylinder with a rod lock for fail-safe holding. At 160 mm of extension, external guidance is strongly advised to keep bending loads off the 16 mm rod.
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 MARU40X160S FAQ
Push at 0.5 MPa is 628.3 N and pull 527.8 N; at 0.7 MPa, push 879.6 N and pull 738.9 N; theoretical max 128.1 kgf at 1.0 MPa. Double acting with variable cushion, 0.15-1.0 MPa (22-145 psi) operating pressure, 30-800 mm/s speed, 160 mm stroke, 1/8 inch ports.
No. The MAR front cover carries its own up/top bracket, so the cylinder bolts directly to a machine face - there is no separate flange or foot to buy. I and Y rod knuckles still thread onto the M12x1.25 rod end if a coupling is needed.
