Airtac MARU Stainless Steel Mini Cylinder MARU32X500S
The AirTAC Airtac MARU Stainless Steel Mini Cylinder MARU32X500S is a genuine double acting + cushion (up mount) standard round-body mini air cylinder with a Ø32mm bore and 500mm 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 MARU32X500S
Maximum standard travel for the bore: the MARU32X500S stretches a 32 mm mini cylinder to a full 500 mm stroke while staying double acting with variable cushions at both ends and an integrated U top bracket. On 0.15-1.0 MPa (22-145 psi) air it produces a 402 N push and a 346 N pull at 0.5 MPa.
The stainless round tube with a hard-chrome plated 12 mm rod keeps its seal and finish in damp, food-grade or outdoor spots where painted minis corrode. Rolling-packed aluminium covers hold the barrel true over the long span. Divide the 402 N push by gravity and you get about 41 kgf of lift; halve that for a 2:1 margin and the cylinder comfortably raises roughly 20 kg vertically. Cushion needles let you dial out the arrival shock when the stroke runs fast.

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 MARU32X500S Is Used
Sortation diverter gate
Pushes parcels across a warehouse sorter lane; the 500 mm sweep covers a full belt width and 402 N at 0.5 MPa moves cartons up to about 24 kg of resistance.
Pallet layer pusher
Squares a layer of bags or boxes on a low-cost palletizing cell; the long stroke reaches across a standard half-pallet while cushions protect the frame.
Welding fixture lift column
Raises a light welding jig into the operator window; with about 20 kg of vertical lift on a 2:1 margin it handles the fixture weight with headroom.
Is the Airtac MARU Stainless Steel Mini Cylinder MARU32X500S the Right Cylinder?
For 500 mm of travel this is the top of the standard 32 mm range - no special stroke is needed. Compare a 25 mm bore at 245 N [email protected] or a 40 mm bore at 628 N if the load demands more muscle. Over this length, side loads bend the rod: guide the load in external slides and keep thrust in line with the bore axis. If the machine must hold the piston against air loss, a separate rod lock is required - the MAR itself drifts. Ports are 1/8 in.; the standard magnet works with CMSG / DMSG / EMSG switches along the full stroke.
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 MARU32X500S FAQ
Push 402 N and pull 346 N at 0.5 MPa; push 563 N at 0.7 MPa; theoretical maximum 82 kgf at 1.0 MPa. Bore 32 mm, stroke 500 mm, rod 12 mm with M10x1.25 thread, 1/8 in. ports, speed 30-800 mm/s.
The U front bracket is integrated into the front cover, so the cylinder bolts straight to the machine top - there is no separate flange or foot to buy for the MAR series. I and Y rod knuckles still fit the 12 mm rod thread when the load needs a swivel joint.
