Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X75SCM
The AirTAC Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X75SCM is a genuine single acting, push (spring return) round-body mini air cylinder with a Ø20mm bore and 75mm stroke, 1/8" 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 MSI Single Acting Stainless Steel Mini Cylinder MSI20X75SCM
Delivering 119.5 N of push force at 0.5 MPa (182.3 N at 0.7 MPa), this AirTAC stainless-steel round-body mini cylinder uses compressed air to extend the rod and an internal mechanical spring to retract it. Because it is a single-acting push type, you only need one 1/8" air line, which saves on plumbing and ensures the rod safely springs back to its retracted rest position if air pressure drops. The Ø20 mm bore features an Ø8 mm piston rod with an M8x1.25 male thread, and the stainless construction shrugs off mild washdown environments.
The built-in piston magnet (-S suffix) allows for direct mounting of CMSG, DMSG, or EMSG sensors for position confirmation, while the CM round end cover handles the rear porting orientation. With a practical safe working load of roughly 72 N, it can reliably clamp or vertically lift components up to about 6.1 kg using a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at the stroke ends without requiring manual adjustment.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X75SCM Is Used
Part Ejection
Uses the 119.5 N push stroke to positively eject machined parts from a fixture, with the spring ensuring a fail-safe retract when air is removed.
Flow Diverter Gate
Actuates a lightweight routing gate on a packaging line; the single 1/8" air port keeps the pneumatic footprint minimal along the conveyor.
Carton Clamping
Provides secure holding force for light carton positioning, safely lifting or pressing loads up to 6.1 kg with a 2:1 safety margin.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X75SCM the Right Cylinder?
When sizing this 20 mm bore unit, compare its 119.5 N push force at 0.5 MPa against your actual load: stepping down to an MSI16X75SCM yields 74.9 N, while moving up to an MSI25X75SCM provides 190.3 N. You must supply at least 0.2 MPa of air pressure to overcome the internal return spring, or the rod will not extend. The 75 mm stroke sits just under the 80 mm maximum standard travel for this bore, making it an optimal, readily available choice. Mounting is highly versatile via standard ISO 6432 mini-cylinder brackets, including LB foot, FA flange, SDB pivot-block, or TC trunnion styles.
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 MSI Single Acting Stainless Steel Mini Cylinder MSI20X75SCM FAQ
This single-acting push cylinder generates 119.5 N of thrust at 0.5 MPa and 182.3 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. Upon venting, the spring immediately drives the rod back to its normally retracted rest state.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG, and EMSG reed or electronic switches. Deceleration is handled solely by fixed TPU bumper pads at the stroke ends; it does not feature an adjustable air cushion.
