Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 500mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 500 mm strokes with ease. The Ø25 mm bore conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration.
The riveted stainless barrel and Ø10 mm rod resist mild corrosion and washdown environments better than painted alternatives. Fixed TPU bumper pads absorb stroke-end impact across the 30-800 mm/s speed range. For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which means it lifts about 12.5 kg vertically with a 2:1 safety margin. The built-in magnet supports CMSG, DMSG and EMSG switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCA Is Used
Diverting Heavy Cartons
Pushes heavy packaged goods between conveyor lanes using the full 245.3 N thrust at 0.5 MPa, surviving damp washdown zones thanks to the stainless build.
Vertical Parts Ejection
Lifts moulded plastic parts out of a forming press, safely handling components up to 12.5 kg vertically during the 500 mm ejection cycle.
Textile Beam Indexing
Shifts large textile beams along a processing line, using the CA clevis mount to accommodate angular misalignment during the long 500 mm transfer.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCA the Right Cylinder?
Sizing this 500 mm stroke unit requires checking both neighbours: the Ø20 bore provides 157.0 N push at 0.5 MPa, while the larger non-ISO Ø32 offers 402.2 N. If your payload is lighter, the Ø20 saves space, but for loads approaching 12.5 kg, this Ø25 is the correct choice. Because air pressure alone will not hold the load if the valve is centred or air is lost, the piston will drift; use a pilot-operated check valve or an external rod lock for suspended loads.
The CA rear pivot cover suits angular movement, complementing available LB foot, FA flange and TC trunnion mounts. The 1/8" port matches the bore size, and the -S magnet enables position sensing. On a long 500 mm extension, minimize side-loading to prevent rod bending and premature seal wear.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
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 Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MI25~40 Stainless Steel Mini Cylinder MI25X500SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8" (PT standard, G optional) and the male rod thread is M10x1.25.
No, the piston drifts if air is lost or the valve is centred; you need a pilot check valve or external rod lock to hold a load. It uses fixed TPU bumper pads that decelerate the stroke end but are not an adjustable air cushion. The -S magnet allows CMSG, DMSG and EMSG sensors for position detection.
