About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SU
Generating 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial actuation duties. The stainless-steel barrel and Ø12 mm rod supply mild corrosion resistance, performing reliably in damp or washdown settings where painted units fail. A 1/8" port feeds the bore, while fixed TPU bumper pads absorb end-of-stroke impacts.
Because the 402.2 N rating represents an ideal maximum, plan for a safe working load of roughly 241 N to account for friction and pressure drops. This translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG position sensing, and the U-style rear cover provides a 90-degree mounting interface.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SU Is Used
Bottling Line Diverter
Pushes heavy crates on a packaging conveyor using its 402.2 N thrust, with the stainless build surviving daily washdown sprays.
Pallet Stop Gate
Acts as a robust 100 mm stroke stop gate for loaded pallets, safely halting 20 kg sections via the U-style 90-degree mount.
Textile Loom Tensioner
Maintains fabric tension on an industrial loom, using CMSG sensors to confirm the 32 mm piston position under humid conditions.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SU the Right Cylinder?
When sizing this 32 mm bore unit, compare it against adjacent options: a 25 mm model yields 245.3 N of push at 0.5 MPa, whereas the larger 40 mm bore generates 628.3 N. If your machine loses air or the valve centres, this standard cylinder will drift and cannot hold a load—the TPU pads only decelerate the stroke end, so add an external rod lock or pilot check valve for suspension. The 100 mm stroke is well within the 500 mm maximum, keeping rod bending stresses low.
Mounting flexibility comes from LB foot brackets, FA flanges, SDB pivot blocks and TC trunnions. The integrated magnet allows direct fitting of CMSG, DMSG or EMSG switches. For high-speed cycles requiring adjustable air cushioning rather than fixed bumpers, evaluate the MIC variant.
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 MI32X100SU FAQ
This 32 mm bore cylinder features a 1/8" 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 of 82 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and do not act as a brake. If air is lost, the rod will drift, so you must fit an external rod lock or pilot-operated check valve to suspend a load safely.
