About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X160SR
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The 25 mm bore uses a 1/8" air port and an M10x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The rolled, riveted construction keeps the unit compact while fixed TPU bumper pads absorb end-of-stroke impacts.
Because it carries the -S suffix, a built-in piston magnet enables position sensing with CMSG, DMSG or EMSG switches. The R back cover features an axial-in port orientation for tidy plumbing. For practical sizing, plan for roughly 147 N of usable work at 0.5 MPa; vertically, it lifts about 12.5 kg with a 2:1 safety margin. This 160 mm stroke is well within the 500 mm maximum standard range.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X160SR Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245.3 N push force to redirect heavy cartons reliably.
Parts Press Fixture
Pushes a lightweight locating pin into a machined housing, absorbing the stroke-end impact via fixed TPU pads.
Damp Storage Ejector
Ejects completed workpieces from a humid staging area, leveraging the stainless steel rod for corrosion resistance.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X160SR the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm cylinder drops the 0.5 MPa push force to 157.0 N, while moving up to a 32 mm bore raises it to 402.2 N. The 160 mm stroke provides ample travel without approaching the 500 mm limit, though long rods require careful alignment to prevent side-loading and rod bending. The ISO 6432 mounting interface drops directly into standard mini-cylinder brackets, with LB foot, FA flange, SDB pivot and TC trunnion options available.
A standard double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. The -S magnet pairs directly with CMSG, DMSG and EMSG sensors for end-position confirmation.
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 MI25X160SR FAQ
The 25 mm bore has a 1/8" air port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No, the piston drifts on air loss; the fixed TPU bumpers only decelerate the stroke end and do not lock the load. Use an external rod lock for holding. The -S magnet allows CMSG, DMSG and EMSG switches for position sensing.
