Airtac MARU Stainless Steel Mini Cylinder MARU50X175S
The AirTAC MARU Stainless Steel Mini Cylinder MARU50X175S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø50mm bore and 175mm 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 MARU50X175S
At 175 mm of stroke, this MAR gives a 50 mm bore that pushes 981.3 N at 0.5 MPa, double acting with a variable air cushion at each end and an up/top mounting bracket built into the front cover, so no separate foot or flange is needed to bolt it to the machine.
The riveted round body pairs a stainless-steel barrel with a hard-chrome plated rod, an edge over painted-steel minis in damp, washed-down or outdoor spots. Turn the cushion needle screws in on first run to kill end-of-stroke shock, then run faster or carry heavier loads without hammering the covers.

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 MARU50X175S Is Used
Belt-line reject pusher
Knocks under-filled tubs off a dairy filling line; the 175 mm travel clears a wide lane while 981.3 N at 0.5 MPa shoves the tub firmly into the reject chute.
Case hold-down on a carton taper
Presses corrugated flap stacks square while the tape head cycles; about 589 N of dependable clamp force at 0.5 MPa handles medium board without crushing.
Washdown divert gate on a food line
Swaps product flow between two chutes; the stainless barrel and chrome rod survive daily caustic hose-down that ruins painted-steel actuators.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU50X175S the Right Cylinder?
Between bores: the 40 mm MAR delivers 628.3 N at 0.5 MPa, this 50 mm bore 981.3 N, and the 63 mm version 1557.9 N, so move one size only when the load genuinely needs it. Air ports are 1/4 in. and the rod thread is M14x1.5; working pressure is 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s. The magnet comes standard, so CMSG, DMSG or EMSG switches mount without a special piston. Note that a plain MAR drifts when air is lost - the cushion softens the stroke end but holds nothing - so add a rod lock where position must stay. With 175 mm of travel, keep side loads off the 16 mm rod; misalignment here bends rods and eats seals early.
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 MARU50X175S FAQ
At 0.5 MPa it pushes 981.3 N and pulls 880.8 N; at 0.7 MPa push rises to 1373.8 N and pull to 1233.1 N. Theoretical peak at 1.0 MPa is 200.1 kgf. A practical design figure is about 589 N of working push at 0.5 MPa.
No, it is built in as standard. CMSG, DMSG or EMSG switches clip onto the stainless barrel for end-of-stroke or mid-stroke signaling, no special-order piston needed. Ports are 1/4 in. and the rod thread is M14x1.5.
