About the Airtac MICJ Adjustable Mini Cylinder MICJ20X60-20S
Dial in a precise forward stop on-site with the AirTAC MICJ20X60-20S, a stainless-steel round-body mini cylinder featuring a 20 mm adjustable extend stroke. An external stop screw trims the forward end position down to 40 mm without swapping hardware, while a needle-set variable air cushion at both ends absorbs high-speed shock. Driven by a 1/8" port and an Ø8 mm rod, this double-acting actuator delivers 157 N of push force at 0.5 MPa.
Built with a riveted stainless barrel and rod for mild washdown resistance, it conforms to the ISO 6432 mounting interface for straightforward bracket drops. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG sensors for position tracking. Based on the 0.5 MPa thrust, it handles a safe working load of roughly 94 N, moving about 8 kg vertically with a 2:1 margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X60-20S Is Used
Divert Gate Positioning
Trims the extend stroke by up to 20 mm to hit a precise divert gate angle on a conveyor, using the dual air cushions to soften the 157 N impact at high cycling speeds.
Carton Flap Folding
Adjusts the forward stop on the fly to match varying carton depths, relying on the 8 kg vertical lift capacity to fold heavy corrugated flaps without slamming.
Light Press Assembly
Presses small bearings with a safe 94 N working load, dialing in the exact 40-60 mm extend position while the stainless construction resists shop coolant.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X60-20S the Right Cylinder?
When sizing this 20 mm bore, step down to a 16 mm variant for lighter 100 N moves, or up to a 25 mm bore when you need 245 N of push force at 0.5 MPa. The MICJ20X60-20S excels in fast set-position tasks where the 20 mm extend trim and dual cushions prevent end-of-stroke banging. Choose LB foot, FA flange, or TC trunnion mounts, noting the SDB pivot block is not offered on this adjustable variant.
Remember that the stop screw sets the end position but acts as no mid-stroke lock. The cylinder will drift on air loss, as the cushion only decelerates near the stroke end. For suspended loads, pair it with an external rod lock or pilot check valve. Add CMSG, DMSG, or EMSG switches directly, as the -S magnet is already integrated.
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 MICJ Adjustable Mini Cylinder MICJ20X60-20S FAQ
This 20 mm bore cylinder uses a 1/8" port and delivers 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (usable range 40-60 mm), while the needle-set air cushion at both ends decelerates the piston near stroke ends. It does not hold position on air loss; for suspended loads use an external rod lock. The -S magnet enables CMSG, DMSG, or EMSG sensors.
