Airtac MARU Stainless Steel Mini Cylinder MARU20X175S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU20X175S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø20mm bore and 175mm stroke, 1/8" 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 MARU20X175S
A 175 mm stroke on the smallest MAR bore gives the MARU20X175S a long, slim working envelope for light push-and-pull jobs. Inside, a two-way heterogeneous piston seal doubles as a grease reservoir, keeping friction low over millions of cycles in the riveted stainless body. Fed at 0.5 MPa the cylinder develops 157 N forward and 131.9 N on return; at 0.7 MPa push climbs to 219.8 N. Cushion needles at both covers trim end-of-stroke shock on fast runs.
Budget around 94 N for continuous work - the sensible slice of the 157 N rating - enough to hoist about 8 kg vertically with a 2:1 margin. Sensing costs nothing extra: the magnet is factory-fitted, so CMSG, DMSG or EMSG switches clip onto the barrel anywhere in the stroke. Supply air 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, proof pressure 1.5 MPa (215 psi).

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Is the Airtac MARU Stainless Steel Mini Cylinder MARU20X175S the Right Cylinder?
There is no smaller MAR bore, so 20 mm with 157 N at 0.5 MPa is the entry point; a 25 mm MAR with 245 N suits heavier clamping. Because the long thin rod sees side loads at full extension, guide the load externally or add a knuckle (M8x1.25) where misalignment exists. The integrated top bracket removes the need for a purchased flange; keep in mind the rod creeps if air is lost, so interlock or lock any gravity load.
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 MARU20X175S FAQ
At 0.5 MPa: 157 N extending, 131.9 N retracting. At 0.7 MPa: 219.8 N extending, 184.7 N retracting. Theoretical peak at 1.0 MPa is 32 kgf. It pairs with 0.15-1.0 MPa (22-145 psi) air, 30-800 mm/s speed, 1/8" ports and an 8 mm rod threaded M8x1.25.
The rolled stainless tube resists rust and mild washdown chemicals far better than painted aluminium minis, so the MARU20X175S holds up in damp food, outdoor or coolant-mist settings. Combined with the 20 um hard-chrome rod, wear stays low and the standard magnet keeps CMSG/EMSG sensing accurate along the whole 175 mm stroke.
