Airtac MFCJ Adjustable Mini Cylinder MFCJ40X150-100
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X150-100 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MFCJ40X150-100
Dial in exact end positions and soak up high-speed shock with the AirTAC MFCJ40X150-100 mini cylinder. This double-acting JIS-standard round-body unit features a SUS304 stainless barrel and riveted aluminium covers, giving you a 100 mm external window to shorten the extend stroke on site. It pushes with 628.3 N at 0.5 MPa and pulls 527.8 N, making it robust enough for heavy mid-range tasks.
The variable needle air cushion at both ends ensures smooth deceleration, while the compact body is intentionally shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. With a 1/4" port and M14x1.5 male rod thread, it yields a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X150-100 Is Used
Press Fit Tuning
Adjust the 100 mm extend window on site to find the exact press-fit depth for 628.3 N push force assemblies, while the air cushion absorbs the high-speed impact.
Heavy Diverter Stroke Setup
Shorten the extend stroke during conveyor changeovers to deflect heavier 32 kg product loads smoothly without hard mechanical crashes.
Clamp Positioning
Fine-tune the clamping reach on machining fixtures, using the variable cushion to bring high-speed moves to a quiet, controlled stop before the cut begins.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X150-100 the Right Cylinder?
When sizing this series, compare the real 0.5 MPa figures: this 40 mm bore pushes 628.3 N, whereas the smaller MFCJ32 pushes 402.2 N. Choose the 40 mm bore when moving heavier jigs or overcoming high friction, and rely on the 100 mm adjuster window to perfect the extend endpoint during trial fits or machine changeovers without machining new parts.
Remember that the air cushion only decelerates the piston near the end of stroke; it does not lock or hold the load. If your application must resist drift on air loss, install an external rod lock or pilot check valve. Mounting options include LB foot, FA flange, and TC trunnion (no SDB), but note this non-magnet version cannot support position sensing.
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 MFCJ40X150-100 FAQ
This 40 mm bore cylinder uses a 1/4" port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The external adjuster only shortens the extend stroke, and the cushion decelerates motion rather than locking the load.
