Airtac MARU Stainless Steel Mini Cylinder MARU40X60S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU40X60S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MARU40X60S
Sixty millimetres of stroke is the sweet spot for reject and press jobs, and the MARU40X60S delivers it double-acting with a variable cushion at both ends and a top-mount bracket riveted into the front cover - the mount travels with the cylinder, so there is no separate flange or foot to buy. Speed spans 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).
At 0.5 MPa the 40 mm bore pushes 628 N and pulls 528 N; at 0.7 MPa push climbs to 880 N against a 128.1 kgf theoretical maximum. Budget about 377 N for the actual job and the cylinder lifts close to 32 kg vertically with a 2:1 margin. The stainless barrel shrugs off splash and washdown, the piston ships with its magnet as standard for CMSG / DMSG / EMSG sensing, and the 16 mm hard-chrome rod keeps running true in gritty 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 MARU40X60S Is Used
Reject gate on a checkweigher
Sixty millimetres is enough to kick underweight packs off the belt, and the cushion tames the gate stop at high line speed.
Slide stopper on an assembly conveyor
The integrated top bracket pins the stop to the frame, and 528 N of pull retracts it clear of passing totes in milliseconds.
Cap press on a cosmetics line
One cushioned 60 mm stroke seats pump tops with 628 N of force, gentle enough for fragile glass bottles on the starwheel.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU40X60S the Right Cylinder?
Drop to the 32 mm MAR (402 N push at 0.5 MPa) for lighter gates, or take the 50 mm bore (981 N) when the reject mechanism is heavy; at 628 N this bore sits between them. Air loss means the rod simply follows the load - there is no holding function in a standard MAR - so add a rod lock if the gate must park mid-stroke. At 60 mm of travel there is little rod overhang, but keep the load centered on the 16 mm rod all the same. The built-in top bracket and factory-fitted magnet (EMSG / DMSG / CMSG compatible) cover mounting and feedback without extra hardware.
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 MARU40X60S FAQ
Bore 40 mm, stroke 60 mm, double-acting with variable air cushioning at both ends and a built-in up-mount. Forces: 628 N push and 528 N pull at 0.5 MPa, 880 N push and 739 N pull at 0.7 MPa, 128.1 kgf theoretical maximum at 1.0 MPa. Rod 16 mm, male thread M12x1.25, ports 1/8", operating pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Every MAR ships with the piston magnet already installed, so AirTAC CMSG, DMSG and EMSG switches mount at any point on the stainless tube and read end positions directly. Order the switch type for your controller - reed or solid state - and it drops on without modifying the cylinder.
