Airtac MARU Stainless Steel Mini Cylinder MARU50X160S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X160S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 160mm 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 MARU50X160S
Cushioned at both ends and pushing 981 N at 0.5 MPa, the MARU50X160S covers the longer medium-stroke duties in the MAR 50 mm family. The up-type front bracket is part of the riveted body - stainless tube, aluminium covers, hard-chrome 16 mm rod - so the cylinder lands on your machine plate without accessory hardware. Double acting with a variable cushion, 30-800 mm/s, air filtered to 40 um.
Size it on about 589 N of dependable push at 0.5 MPa rather than the headline 981 N. Vertically, that bore will hold roughly 100 kg, and lifting about 50 kg with a 2:1 margin lets you match real product weights. The built-in magnet pairs with CMSG / DMSG / EMSG switches, so you get end-of-stroke confirmation on the 160 mm travel without ordering anything special.

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 MARU50X160S Is Used
Chute diverter flap
Swings a diverter flap between two chute lanes; 160 mm of travel clears tall cartons and the cushion stops the slam.
Bundle squaring arm
Squares bundles on a strapping table with about 589 N of working push at 0.5 MPa, tuned via the both-end cushion.
Robot gripper riser
Lifts a light gripper assembly of about 50 kg vertical equivalent between pick and place stations in a humid shop.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X160S the Right Cylinder?
The 40 mm MAR pushes 628 N at 0.5 MPa if you can shrink the bore; the 63 mm class delivers 1558 N when loads climb. A plain MAR releases its position if supply air fails - plan a rod lock wherever that matters. With 160 mm of rod exposed, support and guide the load to keep bending and side load away from the barrel, and remember the 1/4 inch port and M14x1.5 rod thread when plumbing.
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 MARU50X160S FAQ
Extend force is 981 N and retract 881 N at 0.5 MPa; at 0.7 MPa you get 1374 N and 1233 N. Theoretical ceiling is about 200 kgf at 1.0 MPa. Porting is 1/4 inch for this 50 mm bore, rod 16 mm with an M14x1.5 male thread.
No - like any standard double-acting MAR, the piston drifts when supply pressure is lost, since the variable cushion only softens the stroke ends. Fit a rod lock cylinder if the load must stay put. The stainless tube and chrome rod do, however, keep the unit reliable in damp or washdown settings.
