About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X40SCMTC
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X40SCMTC is a double-acting round-body mini cylinder built for demanding mid-range automation. Its stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion, making it highly reliable in damp or washdown environments compared to painted alternatives. The CM round rear cover and TC trunnion mounting provide versatile installation options for this 40 mm stroke unit.
Because the 1/8" port drives a large piston area quickly, operators should plan for a safe working load of roughly 241 N rather than the absolute maximum rating. This translates to lifting about 20.5 kg vertically with a 2:1 safety margin, allowing precise matching of real part weights. Fixed TPU bumper pads absorb the impact at stroke ends to protect the mechanism, and the built-in -S magnet supports CMSG, DMSG and EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X40SCMTC Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 402.2 N thrust to push heavy cartons smoothly into secondary lanes without stalling.
Clamping Fixture
Secures aluminum housings during CNC machining, leveraging the 241 N safe working load to hold parts rigidly against cutting forces.
Vertical Parts Lift
Raises 20 kg tote bins between conveyor tiers, taking advantage of the stainless construction to withstand humid warehouse conditions.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X40SCMTC the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm cylinder reduces the 0.5 MPa push force to 245.3 N, while jumping up to a 40 mm bore increases it to 628.3 N. The TC trunnion mount pairs with the CM round back cover to handle pivoting loads effectively, though you must ensure the 40 mm stroke is not subjected to excessive side loading that could bend the rod. Remember that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as a lock. If your process requires the rod to stay put during a loss of air pressure or when a valve is centered, you must integrate an external rod lock or a pilot-operated check valve to prevent drift.
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 MI32X40SCMTC FAQ
This 32 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet designed for CMSG, DMSG and EMSG switches. The TC accessory denotes a trunnion mount, which combined with the CM round rear cover, allows the cylinder body to pivot smoothly during operation.
