Airtac MICJ Adjustable Mini Cylinder MICJ25X50-50S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X50-50S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm 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 MICJ25X50-50S
Trim the forward stop by up to 50 mm on site with the AirTAC MICJ25X50-50S, a double-acting round-body mini cylinder built from stainless steel for mild washdown resistance. An external screw shortens the extend end position, while a needle-set variable air cushion at both ends soaks up high-speed shock. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches.
Delivering 245.3 N of push force at 0.5 MPa (206.1 N pull) through a 1/8" port and M10x1.25 male rod thread, it handles a safe working load of roughly 147 N. That translates to a vertical lift capacity of about 12.5 kg with a 2:1 safety margin. The Ø25 body conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X50-50S Is Used
Adjustable Clamping
Dial in the 50 mm extend stop to clamp parts of varying widths, using the 245 N push force to secure components during machining.
Sorting Diverter
Absorb high-speed impacts when deflecting packages on a line; the dual air cushions soak up the shock while the -S magnet tracks position.
Product Pusher
Push lightweight cartons into a loading chute with a safe 147 N working load, fine-tuning the forward reach without reprogramming controls.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X50-50S the Right Cylinder?
When sizing this 25 mm bore, stepping down to a MICJ20 drops the 0.5 MPa push force to 157 N, whereas moving up to a MICJ32 raises it to 402 N. Choose this model when you need fast, repeatable set-position moves; the external stop screw dials in the extend end without swapping cylinders, and the dual adjustable cushions decelerate the impact at speeds up to 800 mm/s. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot-block is not offered on this adjustable variant). Remember that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads.
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 MICJ25X50-50S FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull; at 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. This bore uses a 1/8" air port and an M10x1.25 male rod thread.
An external screw shortens the extend stroke by up to 50 mm on site, and a needle valve adjusts the variable air cushion at both ends to decelerate high-speed moves. The cushion only slows the piston near the end of travel—it is not a brake. The cylinder does not hold position on air loss; use an external rod lock for that. The -S magnet enables CMSG, DMSG, and EMSG sensors.
