Airtac MARU Stainless Steel Mini Cylinder MARU50X100S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X100S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 100mm 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 MARU50X100S
Step up to the 50 mm bore and the MARU50X100S doubles the muscle: 981 N of push and 881 N of pull at 0.5 MPa, climbing to 1374 N at 0.7 MPa, with 200 kgf available at the 1.0 MPa theoretical maximum. The 100 mm stroke, double-acting design and variable cushions at each end make it a comfortable driver for heavier clamping and pushing jobs, and the up-mount bracket ships as part of the cylinder.
The 1/4" ports feed this bigger bore, and the stainless barrel with its hard-chrome 16 mm rod holds up where painted mini bodies flake. Set the cushion screws on commissioning and you can use the full 30-800 mm/s speed window without hammering the covers. A standard magnet welcomes CMSG or EMSG switches out of the box. Working numbers: about 589 N of usable push at 0.5 MPa, equal to lifting some 50 kg vertically with a 2:1 margin.

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 MARU50X100S Is Used
Bench ram for bushings
Presses bearings or bushings into housings on a bench ram, using about 589 N of usable push at 0.5 MPa for the job.
Attachment clamp arm
Operates a clamp arm on a strapping or palletising fixture, with 100 mm of travel to close on varying part heights.
Heavy carton kicker
Diverts heavy cartons off a conveyor with a decisive 981 N push, cushions tuned so the gate does not slam home.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X100S the Right Cylinder?
This 50 mm bore sits above the 40 mm MAR (628 N at 0.5 MPa) and below the 63 mm size (1558 N at 0.5 MPa), so loads from 50 to 90 kg have a clear home. Like every plain MAR it will not hold position on air loss; the cushion only dampens the stroke end, so pair it with a rod lock for secure stops. The up bracket is integral, the 1/4" ports allow faster filling, and DMSG / EMSG switches attach directly thanks to the standard magnet.
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 MARU50X100S FAQ
The 50 mm bore pushes 981 N and pulls 881 N at 0.5 MPa; at 0.7 MPa push is 1374 N. The theoretical maximum at 1.0 MPa is 200 kgf. It runs on 0.15-1.0 MPa (22-145 psi) air and withstands 1.5 MPa (215 psi) proof pressure.
The up-mount bracket is integral to the cylinder, so it bolts to the machine with no added flange or foot. Ports are 1/4", matched to the 50 mm bore, and the standard magnet accepts CMSG / DMSG / EMSG switches. Rod thread is M14x1.5 for I or Y knuckles.
