About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500R
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X500R is a robust double-acting round-body mini cylinder built for demanding automation. It features a 32 mm bore, a 500 mm stroke, and a 1/8" air port. The stainless-steel barrel and piston rod provide excellent mild corrosion and washdown resistance, outperforming painted alternatives in damp environments. An axial-in R back cover integrates the rear port neatly along the cylinder axis for tight machinery layouts.
Plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa push rating, to ensure reliable operation. This translates to lifting approximately 20.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads decelerate the piston at both stroke ends to absorb impact. Because this SKU lacks a magnet, it cannot accept CMSG, DMSG, or EMSG position switches; specify the -S variant if electronic sensing is required.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
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 MI25~40 Stainless Steel Mini Cylinder MI32X500R Is Used
Carton Diverting Gate
Actuates a heavy routing flap on a packaging line, using the 402.2 N push force to redirect filled boxes smoothly at high speed.
Vertical Parts Lift
Raises lightweight plastic totes 500 mm between conveyor tiers, safely lifting components weighing up to 20.5 kg with a 2:1 margin.
Washdown Product Ejector
Pushes rejected bottles off a stainless-steel filling line, leveraging the corrosion-resistant barrel to withstand frequent water spray.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500R the Right Cylinder?
When sizing this 32 mm bore, compare your actual load against its 402.2 N push and 345.6 N pull at 0.5 MPa. If you need less force, the 25 mm bore offers 245.3 N push, while stepping up to the 40 mm bore yields 628.3 N. For this 500 mm stroke, minimize side loading to prevent rod bending and premature seal wear. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets. Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered; the TPU bumpers only soften the stroke end and do not act as a brake. Use an external rod lock or pilot check valve if the application requires holding a vertical load.
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 MI32X500R FAQ
This 32 mm bore cylinder has a 1/8" air port and generates 402.2 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet variant if electronic position sensing is required. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion.
