Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X20SCA
The AirTAC Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X20SCA is a genuine single acting, pull (spring return) round-body mini air cylinder with a Ø8mm bore and 20mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X20SCA
Generating 12.3 N of pull force at 0.5 MPa, this AirTAC stainless-steel round-body mini cylinder uses a single-acting pull design. An internal spring keeps the rod extended at rest, meaning your mechanism stays safely forward even if air pressure drops completely. Compressed air through the M5x0.8 port only retracts the 4 mm rod, which saves air and simplifies plumbing.
Built to ISO 6432 mounting dimensions, the Ø8 body drops into standard mini brackets and clevises. The riveted stainless construction resists mild corrosion and washdown environments. With a 20 mm stroke, this CA pivot-cover model yields a safe working load of about 7 N, capable of vertically pulling or holding roughly 0.6 kg against gravity with a 2:1 safety margin. The integrated -S magnet supports CMSG, DMSG and EMSG position sensing.

Where the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X20SCA Is Used
Light Hold-Down Clamp
Keeps a small workpiece or film cover engaged under the 7 N safe load during processing, automatically snapping back to the hold position if the air supply fails.
Tensioning Mechanism
Maintains steady pulling tension on a delicate wire or light web with a 0.6 kg force margin, using the spring-extended rest state to keep the material taut.
Normally-Closed Mini Gate
Blocks a tiny parts lane by default; applying air to the M5x0.8 port retracts the 4 mm rod to drop the gate and let small components pass.
Is the Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI8X20SCA the Right Cylinder?
Size this actuator strictly by its pull force. If 12.3 N at 0.5 MPa is insufficient for your retract stroke, step up to the Ø10 bore which provides 23.2 N; there is no smaller standard bore below Ø8. Remember that at least 0.2 MPa of input pressure is required to overcome the internal return spring before any retraction begins.
The 20 mm stroke sits well within the 50 mm standard limit for Ø8 springs. Mounting is handled via the rear CA pivot clevis, and because this SKU includes the -S magnet, you can directly fit CMSG, DMSG or EMSG sensors for end-of-stroke 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 0.2 – 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 MTI Single Acting Stainless Steel Mini Cylinder MTI8X20SCA FAQ
It provides a 12.3 N pull force at 0.5 MPa and 19.9 N at 0.7 MPa. The rod is normally extended at rest by an internal spring. It requires a minimum of 0.2 MPa air pressure to overcome the spring and retract the rod.
No, the fixed TPU bumpers only soften the stroke ends; the spring returns the rod to full extension on air loss, so it cannot hold an intermediate position. Because this is an -S model with a piston magnet, it supports CMSG, DMSG and EMSG sensors.
