Airtac MARU Stainless Steel Mini Cylinder MARU20X110S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU20X110S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø20mm bore and 110mm 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 MARU20X110S
With 110 mm of travel and a 20 mm bore, the MARU20X110S reaches 157 N pushing and 131.9 N retracting at 0.5 MPa - enough to eject, divert or lift light parts across a full decimeter of stroke. It is double acting with a variable air cushion at both ends and runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air.
Lift math: 157 N at 0.5 MPa equals about 16 kg of theoretical lift, so budget roughly 8 kg for a vertical job with margin to spare. The barrel is stainless steel, the 8 mm rod is hard-chrome plated carbon steel, and the aluminium covers are rolled onto the tube - a riveted body that shrugs off damp shops better than painted minis. Cushion needles on both caps let you soften the landing when you speed up.

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.

Where the Airtac MARU Stainless Steel Mini Cylinder MARU20X110S Is Used
Carton push-off divert
Across 110 mm the rod shoves a small carton off a transfer belt into a chute, with the cushion taking the jolt as the rod bottoms out.
Hopper gate lift
Raising a sliding gate on a pellet hopper outlet is a natural fit for roughly 8 kg of practical vertical lift at 0.5 MPa.
Die part ejection
After a press cycle, the extended rod kicks a formed light-gauge part clear of the die before the next stroke.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU20X110S the Right Cylinder?
For this 20 mm bore the port size is 1/8" and the male rod thread M8x1.25. If your load needs more than roughly 94 N of working force at 0.5 MPa, the next MAR size up, bore 25, delivers 245.3 N on extension. Keep side loads off the 8 mm rod at this longer stroke - guide the part externally if it wants to twist. If the position must hold through an air failure, fit a rod lock; the MAR itself releases and drifts when pressure is gone.
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 MARU20X110S FAQ
Extension force is 157 N at 0.5 MPa and 219.8 N at 0.7 MPa; retraction gives 131.9 N and 184.7 N at the same pressures. The theoretical maximum is 32 kgf at 1.0 MPa, on a double-acting 20 mm bore with variable end cushions.
Yes. Both caps carry a needle-screw variable cushion; open or close it until end-of-stroke noise and rebound disappear, then you can safely push toward the upper end of the 30-800 mm/s speed range.
