Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-20
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-20 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 60mm 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 MFCJ20X60-20
Tune the extend stroke on-site by up to 20 mm with this double-acting, variable-cushion mini cylinder, yielding a usable 40-60 mm extend range. It delivers 157 N of push force at 0.5 MPa and features a SUS304 stainless round body that is shorter than an ISO 6432 unit, saving valuable mounting length.
Fitted with a needle air cushion at both ends to soak up high-speed shock, it handles speeds of 30-800 mm/s. The 1/8" port and Ø8 mm rod keep the frame compact, lifting about 8 kg vertically with a 2:1 margin. Note this SKU lacks a magnet and cannot take a sensor; the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-20 Is Used
Light Parts Ejection
Ideal for pushing small plastic parts out of a mold, using the 20 mm adjuster to dial in the exact 40-60 mm extend distance without crashing the tooling.
Package Diverter
Handles high-speed carton routing where the 157 N push force easily deflects light boxes, while the variable air cushion prevents end-of-stroke slamming.
Lab Test Actuation
Perfect for repetitive test fixtures needing a 60 mm stroke, allowing operators to fine-tune the extend position on the fly for delicate sensor probes.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X60-20 the Right Cylinder?
When sizing, compare this 20 mm bore pushing 157 N at 0.5 MPa against the MFCJ25 at 245.3 N. Choose the 20 mm for lighter, faster changeovers where the 20 mm adjuster window lets you perfect the end position during trial fits without machining. Both bores use a variable air cushion to decelerate smoothly at high speed.
Remember the cushion only slows the piston near stroke end; it is not a lock or brake. If your load must hold position on air loss, add an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (no SDB), and select the -S version if you need 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 MFCJ20X60-20 FAQ
This 20 mm bore cylinder uses a 1/8" port and an Ø8 mm rod. It generates 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, and a theoretical max of 32 kgf at 1.0 MPa.
An external adjuster shortens the extend stroke by up to 20 mm (usable 40-60 mm), while the needle air cushion decelerates the piston at high speed. This specific SKU has no magnet and cannot take a sensor; you need the -S version for CMSG/DMSG/EMSG switches.
