Airtac MARU Stainless Steel Mini Cylinder MARU50X80S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU50X80S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 80mm 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 MARU50X80S
Riveted construction sets the MARU50X80S apart: the aluminium covers and stainless block are rolled onto a 50 mm stainless tube, sealing the 80 mm stroke against dust and splash. Output is 981.3 N push and 880.8 N pull at 0.5 MPa, climbing to 1373.8 N at 0.7 MPa on extension, with a two-way piston seal that stores its own grease.
The U front cover is the mounting - no separate foot or flange to buy, unlike the MAC family where brackets come apart. Keep working loads near 589 N at 0.5 MPa and the 200.1 kgf theoretical ceiling stays out of reach in daily use. Cushion needles at both ends tame end-of-stroke shock, and the factory-fitted magnet means DMSG or CMSG switches drop onto the barrel the day it arrives.

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 MARU50X80S Is Used
Pallet straightener at a dock conveyor
Working thrust around 589 N squares leaning pallets before wrapping; the top bracket ties the unit to the conveyor side rail.
Dye-carriage return on a knitting machine
Pull of 880.8 N at 0.5 MPa snaps the carriage home each cycle; the cushions absorb return energy at speed.
Case divider on a warehouse conveyor
The 80 mm throw pushes one case off the lane; a stainless barrel shrugs off the damp, dusty air of a distribution centre.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X80S the Right Cylinder?
Same bore family, other strokes: 60 mm and 75 mm MAR versions cover shorter throws, and 63 mm (1557.9 N at 0.5 MPa) answers when force rather than travel is the limit. If your frame suits separate foot or flange brackets, the MAC range takes loose accessories; MAR keeps its top bracket formed into the front cover. Guide any lateral load externally - the 80 mm throw on a 16 mm rod is built for thrust, not side wear. Position is not retained on air loss; the load drifts, so spec a rod lock if that matters.
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 MARU50X80S FAQ
Push 981.3 N and pull 880.8 N at 0.5 MPa; push 1373.8 N and pull 1233.1 N at 0.7 MPa; theoretical maximum 200.1 kgf at 1.0 MPa. Bore 50 mm, stroke 80 mm, rod 16 mm with M14x1.5 thread, ports 1/4", speed 30-800 mm/s, operating pressure 0.15-1.0 MPa (22-145 psi).
It is a round-body, riveted design: the aluminium covers and stainless block are rolled onto a stainless barrel, so the joints stay tight and there is no paint to flake off in damp plants. The front cover also integrates the U mounting bracket - one fewer part to order and align.
