Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm 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 MFCJ20X100-10
Trim the extend stroke by up to 10 mm on site with the AirTAC MFCJ20X100-10, a JIS-standard round-body mini cylinder built from SUS304 stainless steel and riveted aluminium covers. The external adjuster sets the end position (usable extend 90-100 mm), while a needle variable air cushion at both ends soaks up high-speed shock for quiet motion.
Delivering 157 N of push force at 0.5 MPa, this double-acting actuator yields a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. It features an 8 mm rod, M8x1.25 male thread, and a 1/8" port. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10 Is Used
Light-Part Ejection
Tune the 10 mm extend window to dial in the exact ejection point of small plastic parts, relying on the variable air cushion to prevent bounce at high speed.
Package Diverting
Ideal for diverting light cartons on a conveyor, where the 94 N safe working load handles the push and the cushion absorbs the repetitive shock.
Lab Test Actuators
Perfect for laboratory trial fits needing precise end-position adjustments, letting operators shorten the stroke on the fly without changing the cylinder.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10 the Right Cylinder?
Weigh the MFCJ20X100-10 against the larger MFCJ25, which steps up to 245.3 N of push force at 0.5 MPa compared to this bore's 157 N. Choose the 20 mm bore for lighter, space-constrained high-speed changeovers where you need to tune both the extend end position and the end-of-stroke cushioning.
The variable air cushion only decelerates the piston near stroke end; it is not a lock or brake, and the cylinder will drift on air loss. For a held load, specify an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (no SDB). If you need position sensing, select the -S magnet variant instead of this base model.
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 MFCJ20X100-10 FAQ
This 20 mm bore cylinder has a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical max of 32 kgf at 1.0 MPa.
No. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. The external adjuster shortens the extend stroke by up to 10 mm, but the variable air cushion only decelerates the piston; it does not lock or hold the load.
