About the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-50
Dial in a precise forward stop without swapping hardware using the AirTAC MICJ20X75-50, a stainless-steel round-body mini cylinder with a 50 mm extend-stroke adjuster. This double-acting actuator uses an external stop screw to shorten the extend end position on site, yielding a usable forward range of 25 to 75 mm, while the retract stroke remains full. A needle-set adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
Built with a corrosion-resistant stainless barrel and an 8 mm rod, it conforms to the ISO 6432 mounting interface for straightforward bracket integration. At 0.5 MPa it delivers 157 N of push force and 131.9 N of pull, making its safe working load roughly 94 N, or about 8 kg of vertical lift with a 2:1 margin. The 1/8" port and M8x1.25 male rod thread keep pneumatic and mechanical connections standard. Note that this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-50 Is Used
Tunable Feed Pusher
Pushing light billets to a stop on a machining line, using the 50 mm extend trim to dial in the exact feed distance and the air cushion to absorb the 157 N impact at high speed.
Soft-Stop Divertor
Actuating a routing gate on a packaging conveyor where the 8 kg vertical lift capacity handles the flap weight, while the dual cushions prevent hard slamming during rapid cycling.
Adjustable Stop Gate
Serving as an adjustable physical end-stop for incoming totes, allowing operators to fine-tune the 25 to 75 mm forward extension on site without changing out the entire cylinder.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X75-50 the Right Cylinder?
When sizing this bore, stepping down to the MICJ16 drops the 0.5 MPa push force to 100.5 N, while stepping up to the MICJ25 raises it to 245.3 N. Choose this 20 mm bore when your application needs around 94 N of safe working force combined with a highly tunable forward position. The 50 mm extend adjuster and dual air cushions are ideal for fast, repeatable set-position moves that require soft deceleration at the ends.
Remember that the stop screw sets only the end position; it is not a mid-stroke lock. Because a standard cylinder does not hold its load on air loss, the piston will drift if pressure drops, so add an external rod lock or pilot check valve for suspended loads. For mounting, LB foot, FA flange, and TC trunnion brackets are available, but the SDB pivot-block is not offered on this adjustable variant.
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 MICJ20X75-50 FAQ
This double-acting cylinder uses a 1/8" air port and an 8 mm rod. 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 50 mm, and a needle valve adjusts the air cushion at both ends to decelerate the piston near the stroke ends. The cushion only slows the piston; it does not lock or hold position. This SKU has no magnet and cannot take sensors, so order a -S variant if you need CMSG, DMSG, or EMSG switches.
