Airtac MFCJ Adjustable Mini Cylinder MFCJ25X75-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X75-50 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 75mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X75-50
Trim the extend stroke by up to 50 mm on site with the AirTAC MFCJ25X75-50, a JIS-standard round-body mini cylinder built for high-speed tuning. The SUS304 stainless barrel and riveted aluminium covers form a compact body that is shorter than an ISO 6432 unit for the same bore and stroke, saving valuable mounting length while resisting mild washdown. A needle variable air cushion at both ends soaks up end-of-stroke shock.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa on a 1/8" port, this double-acting actuator handles a safe working load of about 147 N. It lifts roughly 12.5 kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG switches; choose the -S variant for sensing.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X75-50 Is Used
Adjustable Tooling Stops
Dial in the exact 25-75 mm extend position on machining fixtures, using the 50 mm window to adapt part sizes without reworking hard stops.
High-Speed Diverters
Sort light packages at speed while the variable air cushion silently absorbs the end-of-stroke impact, preventing rebound on the 245 N push stroke.
Carton Forming Pushers
Fine-tune the fold stroke on the fly during carton changeovers, ensuring precise forming pressure without risking damage to the material.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X75-50 the Right Cylinder?
Weigh the MFCJ25X75-50 against the adjacent bores using real 0.5 MPa push forces: the MFCJ20 yields 157 N for lighter tasks, while the MFCJ32 provides 402.2 N when you need heavier drive. This 25 mm bore hits a solid 245.3 N, making it the sweet spot for medium fixture actuation where both the stroke and the end shock need tweaking during changeovers.
The 50 mm adjustable window is perfect for trial fits, letting you dial in the exact extend position without machining spacers. Mount via LB foot, FA flange, or TC trunnion (no SDB). Remember that the air cushion only decelerates the piston near stroke end—it is not a lock. If gravity or air loss could cause drift, fit an external rod lock or pilot check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFCJ Adjustable Mini Cylinder MFCJ25X75-50 FAQ
This 25 mm bore cylinder features a 1/8" port and a 10 mm rod with an M10x1.25 male thread. It delivers 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The external adjuster shortens the extend stroke by up to 50 mm, and the variable air cushion handles deceleration.
