Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-30S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MFCJ25X100-30S
Trim the extend stroke by up to 30 mm on site and dial in a needle air cushion at each end to absorb high-speed shock. This double-acting JIS-standard round-body mini cylinder features a SUS304 stainless barrel with riveted aluminium covers, offering a shorter mounting length than a comparable ISO 6432 unit while resisting mild washdown.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa through a 1/8" port, the Ø10 mm rod handles a safe working load of roughly 147 N. The -S suffix adds a piston magnet for position sensing. Note that the cushion only decelerates the load; it does not function as a brake.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-30S Is Used
High-Speed Forming Press
Dial in the 30 mm stroke adjuster for precise part ejection while the needle cushion absorbs the 245.3 N end impact during rapid cycling.
Package Diverting
Fine-tune the extend position on the fly for varying carton sizes, relying on the built-in magnet to confirm retract home.
Lab Test Fixturing
Safely trial fit delicate components by softening the variable air cushion, preventing damage to parts under the 147 N safe load.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X100-30S the Right Cylinder?
Weigh this 25 mm bore against the MFCJ20 at 157 N or the larger MFCJ32 at 402.2 N (both at 0.5 MPa push) to match your force needs. The 30 mm adjustable window and variable air cushion excel in high-speed changeovers where end-of-stroke shock requires tuning. Mount via LB foot, FA flange, or TC trunnion (no SDB), and use CMSG, DMSG, or EMSG switches with this -S magnet model. For vertical loads, add an external rod lock or pilot check valve, as air loss causes drift.
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 MFCJ25X100-30S FAQ
This 25 mm bore cylinder has a 1/8" port and a Ø10 mm male M10x1.25 rod thread. It generates 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.
The external adjuster shortens the extend stroke by up to 30 mm (usable extend 70-100 mm), while the variable air cushion at both ends decelerates the piston near stroke end. The -S suffix enables CMSG, DMSG, or EMSG sensors; the cushion is for shock absorption only and does not lock the load.
