About the Airtac MICJ Adjustable Mini Cylinder MICJ20X175-40S
Trim the forward stop by up to 40 mm on site without swapping hardware using this AirTAC MICJ20X175-40S mini cylinder. The external screw adjusts the extend end position from 135 to 175 mm, while a needle-set variable air cushion at both ends absorbs high-speed shock. It features a stainless steel round-body barrel and rod for mild corrosion and washdown resistance, and it uses the standard ISO 6432 mounting interface for straightforward bracket integration.
Driven by a 1/8" air port and an Ø8 mm rod with an M8x1.25 male thread, the 20 mm bore delivers 157 N of push force at 0.5 MPa. This translates to a safe working load of roughly 94 N, or the ability to vertically lift about 8 kg with a 2:1 safety margin. The built-in -S piston magnet enables position sensing with CMSG, DMSG, or EMSG switches.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X175-40S Is Used
Adjustable Clamping Press
Dial in the exact 135-175 mm clamping reach on the fly. The 157 N force secures light workpieces while the air cushion prevents slamming at high cycle speeds.
Variable Length Diverter
Extend the rod to push an 8 kg carton off a belt, trimming the forward stroke up to 40 mm on site to accommodate different box sizes without changing brackets.
Tiered Package Stopper
Use the external screw to set precise stopping positions for varying package heights. The stainless build handles mildly humid warehouse environments.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X175-40S the Right Cylinder?
When sizing this 157 N push force unit, consider stepping down to the Ø16 bore for lighter 100 N applications, or moving up to the Ø25 bore if you need 245 N of thrust. This model is ideal for fast, repeatable set-position moves where the 40 mm extend stop and dual air cushions prevent hard impacts at the end of travel.
Remember that the stop screw sets the end position but does not act as a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for suspended loads. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot block is not offered on this adjustable variant), and select CMSG/DMSG/EMSG sensors to leverage the -S magnet.
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 MICJ20X175-40S FAQ
This double-acting 20 mm bore cylinder uses a 1/8" air 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 of 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 40 mm (retract remains full), and a needle valve adjusts the air cushion at both ends to decelerate the piston. The cushion only softens the end-of-stroke impact; it is not a brake, so the cylinder will drift on air loss. The -S magnet allows use with CMSG, DMSG, and EMSG sensors.
