Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 500mm 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 MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCM
Soaking up end-of-stroke shock at high speeds, the AirTAC MFC20X500SCM relies on a needle-set variable air cushion at both ends rather than a simple bumper. This JIS-standard round-body mini cylinder pairs a SUS304 stainless barrel with riveted aluminium covers to shrug off mild corrosion and washdown, while its 500 mm stroke and CM round-end rear cover suit long-travel packaging tasks.
Operating as a double-acting unit on a 1/8" port, the 20 mm bore generates 157 N push and 131.9 N pull at 0.5 MPa. That translates to a safe working load of roughly 94 N, or vertical lifts of about 8 kg with a 2:1 margin. The built-in -S magnet supports CMSG, DMSG and EMSG switches, and the riveted body is noticeably shorter than an ISO 6432 cylinder of the same bore and stroke.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCM Is Used
Long-Stroke Diverting
Pushes light cartons along a packaging line over the full 500 mm travel, using the variable air cushion to stop the 8 kg load gently at speed.
Sample Ejection
Extends small plastic parts out of a moulding area at high cycle rates, relying on the needle-set cushion to prevent end-cap shock.
Bin Sorting
Actuates a lightweight deflector gate across multiple lanes, benefiting from the compact riveted body to save machine space.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCM the Right Cylinder?
For lighter payloads, the 20 mm bore here provides 157 N push at 0.5 MPa; if you need more force, stepping up to the MFC25 yields 245.3 N at the same pressure. Since only bores 20, 25, 32 and 40 exist in this series, sizing down from 20 is not an option. The variable air cushion is essential when cycling heavy loads or operating near the 800 mm/s speed limit, as it decelerates the piston smoothly.
Remember that this cushion only eases the end-of-stroke impact and does not function as a brake; if air pressure drops, the piston will drift. To hold a load securely, install an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion, and the included -S magnet enables 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 MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCM FAQ
This 20 mm bore double-acting cylinder uses a 1/8" port. It delivers 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 maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors. However, the variable air cushion only decelerates the piston near stroke end; it is not a lock. For vertical loads, use an external rod lock or pilot check valve to prevent drifting.
