Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 85mm 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 MFC20X85SCM
Variable air cushions at both ends define this double-acting JIS-standard round-body mini cylinder, letting you dial in needle-set deceleration to absorb high-speed shock. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion, while the CM round-end rear cover and 85 mm stroke support compact layouts. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable mounting length.
In the 20 mm bore class, it generates 157 N of push force at 0.5 MPa, yielding a safe working load of about 94 N or roughly 8 kg of vertical lift with a 2:1 margin. The 1/8 inch port feeds an 8 mm rod with an M8x1.25 male thread. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCM Is Used
Light-Part Ejection
Uses the 157 N push force at 0.5 MPa to knock small moulded components free, relying on the needle-set air cushion to soften the impact at the end of the 85 mm stroke.
Package Diverting
Pushes lightweight cartons off a main belt; the riveted SUS304 stainless barrel handles mildly humid packing environments without issue.
Small-Part Sorting
Cycles rapidly to gate product streams, using the built-in -S magnet with a DMSG switch to confirm position and the dual cushions to reduce end-stroke noise.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCM the Right Cylinder?
When sizing this 20 mm bore option against the next size up, the MFC25 provides a stronger 245.3 N of push force at 0.5 MPa if your load demands it; since 20 mm is the smallest available MFC bore, there is no smaller variant to step down to. The adjustable air cushion is most valuable when cycling at high speeds or moving sensitive masses, where it smooths the end-of-stroke transition.
Remember that the cushion only decelerates the piston near the stroke end and does not function as a lock or brake. If your application must hold a load vertically during air loss or valve centring, fit an external rod lock or pilot-operated check valve. You can mount this unit using LB foot, FA flange, SDB pivot, or TC trunnion hardware.
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 MFC20X85SCM FAQ
This 20 mm bore cylinder has a 1/8 inch port and an 8 mm rod. 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 force of 32 kgf at 1.0 MPa.
No, the piston will drift on air loss. The variable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake. You must add an external rod lock or pilot check valve to hold a suspended load.
