Airtac MARU Stainless Steel Mini Cylinder MARU32X15S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X15S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 15mm 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 MARU32X15S
A 15 mm stroke makes the MARU32X15S a compact kicker and clamp: 32 mm of bore in a riveted stainless round body, double acting, with an up-facing bracket formed into the front cover and a variable cushion at each end. It pushes 402 N and pulls 346 N at 0.5 MPa, and the cushion needles let you tune the short travel to a soft stop on a 0.15-1.0 MPa (22-145 psi) supply.
Because the barrel is stainless and the 12 mm rod is hard-chrome plated to 20 um, splash zones and humid cells are no problem. At 0.5 MPa the honest working figure is about 241 N after derating - enough to vertical-lift around 20 kg once you halve the 41 kgf rating. Speeds span 30-800 mm/s, and the standard piston magnet accepts CMSG, DMSG or EMSG switches.

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 MARU32X15S Is Used
Stamping die slug clear-out
A 15 mm jab at 402 N flicks slugs off the die face between press strokes.
Vision system dodge motion
The short stroke swings the camera out of the robot path, and the cushion gives a flicker-free stop for sharp images.
Aluminium extrusion fixture clamp
About 241 N of derated clamp force holds thin-wall sections against the stop without crushing them.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X15S the Right Cylinder?
For a 15 mm throw, the 20 mm bore (157 N push) is often too weak and the 40 mm (628 N) overkill; 402 N at 0.5 MPa sits neatly in between. Keep side loads off the 12 mm rod at such short travel - the cushion softens the air, not the bearing. Expect the rod to drift if air is lost, so a rod lock is the fix for held positions. The top bracket ships on the cylinder, and I or Y knuckles thread onto the M10x1.25 rod.
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 MARU32X15S FAQ
Push 402 N and pull 346 N at 0.5 MPa, rising to 563 N and 484 N at 0.7 MPa, with a theoretical 82 kgf ceiling at 1.0 MPa. Bore is 32 mm, port 1/8 inch, rod thread M10x1.25, speed 30-800 mm/s.
The variable cushion at both ends still applies - set the needles so the 15 mm travel decelerates smoothly instead of ringing the covers. The stainless round barrel resists corrosion, and the built-in magnet feeds CMSG, DMSG and EMSG switches for part-present signals.
