About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X85SCA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation tasks with ease. The Ø12 mm bore features an M5x0.8 air port and an M6x1.0 male rod thread. Its riveted round-body construction uses a stainless barrel and rod, offering better mild-corrosion and washdown resistance than painted alternatives in damp production areas.
Because this SKU includes the -S magnet, it is ready for CMSG, DMSG or EMSG position switches. The built-in fixed TPU bumper pads absorb stroke-end impact without adjustable cushioning. For practical sizing, plan for a safe working load of roughly 34 N, which means it can lift about 2.9 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X85SCA Is Used
Package Diverter Gate
Pivots a lightweight routing flap on a packaging conveyor, using the CA clevis to accommodate the swing arc while handling the 56.5 N push requirement.
Lab Sample Ejector
Pushes tested specimens out of a small diagnostic carousel, where the stainless build resists chemical mist and the -S magnet confirms ejection via a DMSG sensor.
Small Parts Sorter
Actuates a reject arm to push 2.9 kg off-spec parts off a linear track, relying on the fixed TPU bumpers to quietly stop the 85 mm stroke.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X85SCA the Right Cylinder?
When sizing this 56.5 N (at 0.5 MPa) unit, consider dropping to the Ø8 bore if your load requires under 25.1 N, or stepping up to the Ø16 bore for 100.5 N of push force. The included CA back cover provides a pivot clevis for angular alignment, complementing standard LB, FA, SDB and TC mountings. The ISO 6432 mounting interface on this Ø12 bore ensures it drops directly into standard mini-cylinder brackets.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the TPU pads only decelerate the stroke end rather than locking the rod. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Additionally, the 85 mm stroke is well within the 250 mm maximum, but always guide the rod to prevent side-load bending.
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 MI12X85SCA FAQ
This double-acting cylinder generates 56.5 N push and 42.4 N pull at 0.5 MPa, or 79.1 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M6x1.0.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and do not function as a brake. If air is lost, the rod will drift; for vertical loads, you must use an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to confirm position.
