Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC20X60SCM
The AirTAC Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC20X60SCM is a genuine double acting + 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 B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC20X60SCM
The B52-MFC20X60SCM is the copper-free (copper-prohibited) version of AirTAC's MFC20X60SCM, a JIS-standard round-body mini cylinder built for lines where copper alloys are not permitted. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion, while the variable air cushion at both ends lets you tune deceleration with a needle to kill end-of-stroke shock at high speed. The 20 mm bore delivers 157 N push and 131.9 N pull at 0.5 MPa, giving a safe working load of about 94 N at 60% of that figure.
The B52- prefix marks the copper-free build, meaning specific parts are substituted to exclude copper and copper alloys - the exact replacement materials should be confirmed with us. The front cover carries a fixed anti-impact pad, and the CM round-end back cover is fitted. With a 1/8" port and M8x1.25 male rod thread, this compact cylinder is shorter than an ISO 6432 unit for the same bore and stroke, saving mounting length.

Where the Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC20X60SCM Is Used
High-Speed Pick-and-Place
At 30-800 mm/s, the variable cushion tames the stop on a 60 mm stroke, protecting small parts from impact damage while the copper-free build suits electronics assembly lines.
Ammonia Handling Equipment
The copper-free construction is appropriate for ammonia systems where copper alloys are prohibited, with the stainless barrel resisting mild corrosion from the environment.
Battery Cell Positioning
The -S magnet works with CMSG or DMSG switches to confirm the rod position on each cycle, while the 157 N push at 0.5 MPa moves lightweight battery components into place.
Is the Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC20X60SCM the Right Cylinder?
For a 20 mm bore, the next step up is the MFC25 at 245.3 N push at 0.5 MPa - a 56% force increase if your load is marginal. The variable air cushion is the key differentiator: if you run high cycle rates or carry a heavy load into the end caps, the needle-set cushion soaks up the shock and cuts noise versus a bumper mini. Remember, this cylinder does not hold position on air loss - the piston drifts, and the cushion only decelerates near stroke end. For a held load, add an external rod lock or pilot-operated check valve. The -S magnet enables CMSG, DMSG, or EMSG switches for position sensing. Mounting options include LB foot, FA flange, SDB pivot block, or TC trunnion.
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 B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC20X60SCM FAQ
At 0.5 MPa, push is 157 N and pull is 131.9 N. At 0.7 MPa, push rises to 219.8 N and pull to 184.7 N. Theoretical maximum force is 32 kgf at 1.0 MPa. The bore is 20 mm with a 1/8" port and M8x1.25 rod thread.
B52- marks AirTAC's copper-free (copper-prohibited) build of MFC20X60SCM - specific parts are substituted to exclude copper alloys, but the exact materials should be confirmed with us. The variable air cushion at both ends uses a needle to adjust deceleration, soaking up shock at stroke end. It is not a lock or brake; the piston drifts on air loss.
