About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X145SCA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact automation tasks with precision. The Ø12 mm bore uses an M5×0.8 air port and a Ø6 mm piston rod with an M6×1.0 male thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. The riveted round body keeps the unit light, while fixed TPU bumper pads absorb impact at the stroke ends.
Conforming to ISO 6432 mounting dimensions, the cylinder drops directly into standard mini-cylinder brackets and clevises. Because this SKU includes the -S magnet, it is ready for CMSG, DMSG, or EMSG position switches. Plan for a safe working load of roughly 34 N at 0.5 MPa, which means it can lift about 2.9 kg vertically with a 2:1 safety margin. The CA rear pivot cover provides a robust clevis mount for angular alignment.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X145SCA Is Used
Small Parts Sorting Diverter
Uses the 56.5 N push force at 0.5 MPa to deflect lightweight plastic components on a conveyor belt, relying on the CA clevis to accommodate the pivot arc.
Lab Sample Ejection Mechanism
Leverages the stainless steel construction to withstand humid lab conditions, safely ejecting test tubes weighing under 2.9 kg with a 2:1 vertical lift margin.
PCB Board Pusher Assembly
Employs the -S magnet with a DMSG sensor to confirm stroke position, pushing delicate circuit boards into a testing fixture without adjustable cushion complexity.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X145SCA the Right Cylinder?
When sizing this 12 mm bore, compare it against its neighbours: stepping down to an Ø8 bore drops the push force to 25.1 N at 0.5 MPa, while moving up to a Ø16 bore increases it to 100.5 N. This model includes a CA pivot clevis, making it ideal for articulating mechanisms. The 145 mm stroke is well within the 250 mm maximum standard stroke for this bore, but at this length you should ensure the rod is not subjected to excessive side loads that could cause bending. Remember that a standard cylinder drifts when air is removed or a valve is centred; the bumpers only decelerate the end of travel and do not act as a brake. Use an external rod lock or pilot check valve if you need to hold a load securely.
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 MI8~12 Stainless Steel Mini Cylinder MI12X145SCA FAQ
This double-acting cylinder has an M5×0.8 port and generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push is 79.1 N and the pull is 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the rod at the stroke end and do not function as a locking brake. You must install an external pilot check valve or rod lock to maintain vertical position.
