Airtac MICJ Adjustable Mini Cylinder MICJ20X700-100
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X700-100 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 700mm 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 MICJ Adjustable Mini Cylinder MICJ20X700-100
Dial in a precise forward stop on-site with the AirTAC MICJ20X700-100, a stainless-steel round-body mini cylinder that shortens the extend end by up to 100 mm via an external screw. Because this 700 mm unit exceeds the 500 mm standard stroke for a Ø20 bore, it is supplied as a non-standard, made-to-order item. It delivers 157 N of push force at 0.5 MPa, translating to a safe working load of roughly 94 N or a 2:1 vertical lift capacity of about 8 kg.
Beyond setting the extend position, this double-acting actuator features an adjustable air cushion at both ends to soak up high-speed shock near the stroke limits. The stainless barrel and rod resist mild corrosion and washdown environments. It uses the ISO 6432 mounting interface for standard mini brackets, operates at 30-800 mm/s, and feeds via a 1/8" port. Note this SKU lacks a magnet and cannot take CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X700-100 Is Used
Long-Reach Diverting
Pushes light packages on a sorting line with a 157 N push force, using the 100 mm extend adjustment to tune the stop distance for varying box sizes.
Film Roll Tensioning
Extends a long 700 mm stroke to position packaging material, relying on the adjustable air cushion to prevent end-of-stroke shock at high cycling speeds.
High-Bay Ejection
Ejects totes from a vertical shelf, safely lifting around 8 kg vertically while the external stop screw sets the exact extend endpoint without re-engineering.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X700-100 the Right Cylinder?
When sizing this 157 N push unit, dropping down to a Ø16 bore cuts the 0.5 MPa push force to 100.5 N, while stepping up to a Ø25 bore raises it to 245.3 N. The 100 mm extend adjuster is ideal for fast set-position moves where you need to tune the forward stop without swapping hardware. The adjustable air cushion only decelerates the piston near the end of travel; it is not a mid-stroke lock or brake.
This cylinder does not hold its load on air loss, as the piston will drift—use an external rod lock or pilot-operated check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot-block is not available on adjustable-stroke variants). Because this SKU has no -S magnet, it cannot support position sensing.
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 MICJ20X700-100 FAQ
This Ø20 bore cylinder uses a 1/8" port and an M8x1.25 male rod thread. 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 100 mm on-site, while a needle-set air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The cylinder is double-acting, does not hold position on air loss, and this SKU lacks a magnet for sensors.
