Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SCM
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SCM is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 70mm 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 MI16X70SCM
Delivering 100.5 N of push force at 0.5 MPa, this AirTAC MI16X70SCM is a double-acting round-body mini cylinder built from a stainless-steel barrel and rod. The riveted construction shrinks the footprint while resisting mild corrosion, making it far more suitable for damp washdown environments than painted alternatives. Its 70 mm stroke and 1/8" port provide a compact actuation solution, while the fixed TPU bumper pads absorb end-of-stroke impact without requiring manual adjustment.
Because it carries the -S suffix, the piston includes a magnet for direct mounting of CMSG, DMSG or EMSG switches. The Ø16 bore conforms to ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 60 N of actual work at 0.5 MPa, which translates to safely lifting about 5.1 kg vertically against gravity.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SCM Is Used
PCB Clamping Jigs
Applies steady 60 N holding force on electronic assembly lines, using the 70 mm stroke to secure boards during automated soldering.
Damp Washdown Diverters
The stainless steel rod and barrel survive humid food-packaging environments, actuating flap gates to route wrapped goods at high speed.
Small Part Ejection
Uses the 5.1 kg vertical lift capacity to push lightweight moulded plastic components out of a press cavity before the next cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X70SCM the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N push at 0.5 MPa, whereas stepping up to a 20 mm bore provides 157 N. This makes the MI16X70SCM the sweet spot for medium-duty clamping or lifting tasks. The CM round end back cover offers a clean rear profile for tight spaces. If your process loses air or the valve centres, this cylinder will drift and cannot hold position; the bumpers only decelerate the stroke end. For a suspended load, add an external rod lock or pilot check valve.
With a 70 mm stroke, keep side-loading forces minimal to prevent rod bending. You can mount it using LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions. For high-speed cycles that need variable end-cushioning, look at the MIC variant instead of relying on the fixed bumpers here.
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 MI16X70SCM FAQ
This 16 mm bore cylinder features a 1/8" port and a 6 mm piston rod. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The Ø16 bore adheres to ISO 6432 mounting interface dimensions, allowing it to fit standard brackets. It uses fixed TPU bumper pads for deceleration, not adjustable air cushions.
