Airtac MICJ Adjustable Mini Cylinder MICJ20X50-20
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X50-20 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 50mm 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 MICJ20X50-20
Trim the forward stop by up to 20 mm on site without swapping hardware using this AirTAC MICJ20X50-20 round-body mini cylinder. The external screw adjusts the extend end position from 30 to 50 mm, while a needle-set variable air cushion at both ends soaks up high-speed impact. It delivers 157 N of push force and 131.9 N of pull force at 0.5 MPa, yielding a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin.
Built with a stainless-steel barrel and piston rod, this double-acting unit resists mild corrosion and handles washdown environments. It uses the ISO 6432 mounting interface for standard mini brackets and features a 1/8" port with an M8x1.25 male rod thread. Note that this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X50-20 Is Used
Adjustable Stop Diverter
Dial in the exact 30 to 50 mm extend position on a conveyor diverter gate to handle varying package sizes without changing cylinders.
High-Speed Part Pusher
Use the dual adjustable air cushions to decelerate the 157 N push force smoothly when ejecting light parts at high cycle rates.
Lab Dispense Head
Set a precise forward stop for a liquid dispense nozzle, relying on the stainless construction for mild chemical washdown resistance.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X50-20 the Right Cylinder?
When sizing this 20 mm bore against adjacent options, the smaller 16 mm bore provides 100.5 N of push at 0.5 MPa, whereas stepping up to the 25 mm bore yields 245.3 N. Choose this model when you need precise extend positioning paired with end-cushioning for fast moves. The stop screw sets the end position but does not function as a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for holding loads.
Mounting options include LB foot, FA flange, and TC trunnion, but the SDB pivot block is not available on this adjustable variant. Because this SKU has no internal magnet, position sensing is impossible unless you select the -S version.
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 MICJ20X50-20 FAQ
This 20 mm 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 20 mm, and needle valves adjust the air cushion at both ends to absorb shock. The cushion only decelerates near the stroke end and does not lock the piston; the cylinder cannot hold a load on air loss without an external rod lock. This SKU also lacks a magnet, so it cannot take sensors.
