Airtac MI16-20 Stainless Steel Mini Cylinder MI20X320SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X320SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 320mm 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 MI16-20 Stainless Steel Mini Cylinder MI20X320SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 320 mm stroke with ease. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. Its riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches.
Because the 0.5 MPa push rating rarely translates to pure work output, plan for a safe working load of roughly 94 N. That equates to lifting about 8 kg vertically with a 2:1 safety margin, letting you match the cylinder to real part weights. Fixed TPU bumper pads absorb the impact at stroke extremes, and the rear CA clevis allows pivoting articulation.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X320SCA Is Used
Package Diverter Arm
Uses the CA pivot mount to swing a gating arm on a packaging line, relying on the 157 N push force to redirect light cartons at high cycling speeds.
Storage Tote Pusher
Extends 320 mm to push plastic totes from a gravity roller conveyor, safely moving loads under the 8 kg vertical-lift equivalent threshold.
Lab Sample Ejector
The stainless construction resists humidity in testing chambers, while the -S magnet triggers a DMSG sensor to confirm sample tray ejection.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X320SCA the Right Cylinder?
When sizing this unit, the neighbouring Ø16 bore yields 100.5 N of push at 0.5 MPa, while the larger Ø25 bore steps up to 245.3 N. If your application demands precise end-position deceleration rather than standard bumpers, consider the MIC variable cushion variant. The 320 mm stroke is well within the 500 mm maximum for this bore, but at this length you should carefully manage side loads to prevent rod bending.
The CA rear pivot cover suits articulated mechanisms, but remember that venting or centring the valve causes the piston to drift, as the TPU bumpers only decelerate the end of travel and never act as a brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI16-20 Stainless Steel Mini Cylinder MI20X320SCA FAQ
This Ø20 mm bore cylinder features a 1/8 inch port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, it uses fixed TPU bumper pads to decelerate the stroke end rather than adjustable air cushions. The MIC variant is required for adjustable cushioning. This model also uses ISO 6432 mounting dimensions for standard mini-cylinder brackets.
