Airtac MARU Stainless Steel Mini Cylinder MARU50X150S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X150S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 150mm stroke, 1/4" 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 MARU50X150S
At 150 mm of stroke, the MARU50X150S reaches deep fixtures while still pushing 981 N at 0.5 MPa on extend. This is AirTAC's round-body MAR mini: a stainless barrel with aluminium covers riveted on and a 16 mm hard-chrome plated rod. Double acting throughout, with a variable air cushion at both ends that you trim via the needle screws so end-of-stroke shock stays off the covers at speed.
Because the magnet is built in as standard, position feedback with CMSG, DMSG or EMSG switches is a drop-on affair, not a special order. Working pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating. For sizing, treat about 589 N as the practical push at 0.5 MPa - roughly a 60 kg horizontal shove with margin - and expect about 100 kg of vertical capability, or 50 kg if you halve it for a 2:1 margin.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MARU50X150S Is Used
Gate clamp on a weld cell
Clamps weld fixtures clear of the gun path; the stainless barrel shrugs off weld-spatter coolant and mist where painted minis rust.
Deep-draw ejector
150 mm of stroke ejects formed parts from shallow die cavities, with both-end cushioning easing the return slap at speed.
Palletizer push arm
Rows cartons onto a pallet at moderate speed, delivering about 589 N of useful force per cycle at 0.5 MPa.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X150S the Right Cylinder?
Downsizing to the 40 mm bore saves space but caps you at 628 N at 0.5 MPa; upsizing to 63 mm buys 1558 N if the load grows. Like any plain double-acting cylinder this one will not hold position when air is lost - the cushion is not a brake - so pair it with a rod lock for safety-critical holds. The top bracket is part of the body itself, and the 150 mm stroke deserves external load guidance to keep side loads off the chrome 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 MARU50X150S FAQ
At 0.5 MPa: 981 N extend, 881 N retract. At 0.7 MPa: 1374 N extend, 1233 N retract. Theoretical maximum about 200 kgf at 1.0 MPa. This 50 mm bore uses 1/4 inch ports and a 16 mm rod threaded M14x1.5.
Both come as standard. The piston magnet works with CMSG, DMSG and EMSG switches out of the crate, and the variable cushion at each end is adjusted with needle screws during commissioning so you can run up to 800 mm/s without hard stops.
