Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 50mm stroke, 1/4" 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 MFCJ32X50-30
Dial in the exact extend end-point on-site with the AirTAC MFCJ32X50-30, a JIS-standard round-body mini cylinder built from a SUS304 stainless barrel and riveted aluminium covers. The external adjuster shortens the nominal 50 mm extend stroke by up to 30 mm, while the needle-set variable air cushion at both ends soaks up high-speed shock for smooth, quiet motion.
Delivering 402.2 N of push force at 0.5 MPa, this double-acting unit is ideal for trial fits and rapid changeovers where both the stroke length and end-of-stroke impact need tuning. It features a 1/4" port and a 12 mm rod with an M10x1.25 male thread. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches. For the same bore and stroke, the MF body is shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30 Is Used
Changeover Dial-In
Fine-tune the 20-50 mm extend stroke by up to 30 mm on-site during rapid product format changes, using the 402.2 N push force to seat light tooling without redesigning hard stops.
High-Speed Damping
Leverage the needle variable air cushion to absorb end-of-stroke shock on 800 mm/s cycling test rigs, protecting delicate actuators while the adjuster sets the exact impact point.
Trial Fit Prototyping
Validate new end positions on prototype assemblies by shortening the extend stroke within the 30 mm window, safely pushing loads up to a 241 N working limit at 0.5 MPa.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30 the Right Cylinder?
Choose the MFCJ32 over the MFCJ40 when your application needs roughly 402.2 N of push force at 0.5 MPa rather than the 628.3 N provided by the larger bore, or when stepping up from the 245.3 N of an MFCJ25. The 30 mm adjustable window is perfect for high-speed changeovers and shock-sensitive trial fits, letting you fine-tune the extend position without machining new hard stops. The needle air cushion decelerates the piston near the stroke end but does not function as a lock or brake; the piston will drift on air loss, so add an external rod lock or pilot check valve for suspended loads.
Mount this cylinder using LB foot, FA flange, or TC trunnion brackets (SDB and back-cover mounts are not available on this build). Because this is the non-magnet version, it cannot support CMSG, DMSG, or EMSG sensors—select the -S variant if your control system requires position feedback.
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 MFCJ32X50-30 FAQ
This 32 mm bore cylinder has a 1/4" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet and cannot accept CMSG, DMSG, or EMSG switches. The external adjuster only shortens the extend stroke by up to 30 mm; it does not lock the piston mid-stroke, and the air cushion only decelerates near the ends.
