About the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-20S
Trim the forward stop by up to 20 mm on site without swapping hardware using the AirTAC MICJ25X250-20S. This double-acting, round-body stainless-steel mini cylinder pairs that external extend adjuster with a needle-set variable air cushion at both ends, letting you dial in the exact 230 to 250 mm forward position while soaking up high-speed shock. The stainless barrel and Ø10 mm rod shrug off mild corrosion and washdown environments.
Delivering 245.3 N of push force at 0.5 MPa, it yields a safe working load of roughly 147 N, or about a 12.5 kg vertical lift with a 2:1 safety margin. The built-in -S magnet supports CMSG, DMSG, and EMSG sensors, and the 1/8" port conforms to the ISO 6432 mounting interface for straightforward bracket integration.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-20S Is Used
Precision Cutoff Saw
Trims the 250 mm extend stroke down to exactly 235 mm to drive a cutoff blade, relying on the 245.3 N push force and needle air cushion to stop cleanly without slamming.
Pallet Positioning Gate
Snags pallets on a washdown line; the stainless build resists moisture while the adjustable forward stop fine-tunes the gating distance for various carton sizes.
Component Press Fit
Presses bearings into housings using a safe working load of 147 N, using the 20 mm extend adjustment to dial in the exact bottoming-out depth for different part heights.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-20S the Right Cylinder?
When sizing this 25 mm bore, dropping down to the 20 mm variant cuts your 0.5 MPa push force to 157 N, while stepping up to the 32 mm bore raises it to 402 N. Choose this model when you need those 245.3 N pushes combined with a highly specific extend endpoint, as the stop screw lets you trim the forward stroke by 20 mm on the fly. The dual adjustable air cushions manage deceleration for fast cycling.
Remember that the stop screw sets the end position but does not function as a mid-stroke lock, and the cylinder will drift on air loss. For load holding, install an external rod lock or pilot check valve. Mount via LB, FA, or TC brackets (SDB is not supported here), and use CMSG, DMSG, or EMSG switches enabled by 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 MICJ25X250-20S 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, and the air port is 1/8".
An external screw shortens the extend stroke by up to 20 mm (usable range 230-250 mm), while needle valves adjust the air cushion at both ends to absorb high-speed impact. The -S magnet enables CMSG/DMSG/EMSG sensors. It does not hold position on air loss; use an external rod lock for that.
