Airtac MARU Stainless Steel Mini Cylinder MARU32X35S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X35S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 35mm 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 MARU32X35S
Compact 35 mm throw, full 32 mm muscle: this MAR pushes 402 N at 0.5 MPa and reaches 563 N at 0.7 MPa, in a double-acting format whose top bracket is built into the front cover rather than bolted on later. Variable cushioning at both stroke ends lets you tune impact on first run-up.
The stainless round barrel and 20 um hard-chrome rod take repeated wipe-down in food and packaging lines, and the built-in magnet (standard, shown as S in the code) accepts CMSG / DMSG / EMSG switches out of the box. Treat 402 N as a rating, not a budget: keep real work near 241 N at 0.5 MPa and the cylinder will last.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MARU32X35S Is Used
Welding fixture clamp
Clamps a steel bracket into a spot-welding jig with 402 N of force over a short 35 mm throw; set the needle screws once and every cycle lands quietly.
Bowl-feeder part kick
Kicks wrongly oriented fittings off a vibratory bowl feed track; a DMSG switch confirms each kick before the next part arrives.
Small bearing press
Seats ball bearings into pump housings on a light-duty bench press; keep real work near 241 N and the short stroke stays repeatable shift after shift.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X35S the Right Cylinder?
Downsizing to a 25 mm bore (245 N push at 0.5 MPa) works only for very light clamps; this 32 mm unit at 402 N is the workhorse choice, and a 40 mm bore (628 N) adds headroom for sticky tooling. The up bracket is integral, so there is no FA flange or LB foot to buy; if a separate-foot version ever suits the layout better, the cushioned MAC series takes that role. On air loss the piston simply drifts - the cushion is not a brake - so pair with a rod lock when the clamp must stay shut through a drop.
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 MARU32X35S FAQ
At 0.5 MPa: 402.2 N push, 345.6 N pull. At 0.7 MPa: 563.0 N push, 483.8 N pull. The 32 mm bore tops out at 82.0 kgf theoretical at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof rated 1.5 MPa (215 psi), and run stroke speed anywhere in the 30-800 mm/s band.
Mild washdown is fine: the barrel is stainless steel, the 12 mm rod is carbon steel with a 20 um hard-chrome plate, and the aluminium covers are rolled onto the tube for a sealed, riveted body with no bolted joints to weep. Feed it air filtered to 40 um and keep ambient between -20 and +70 C.
