Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X125SCM
The AirTAC Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X125SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 125mm 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-MFC25X125SCM
The B52-MFC25X125SCM is AirTAC's copper-free (copper-prohibited) version of the MFC25X125SCM, built for lines where copper alloys are not permitted, such as ammonia systems and certain battery or chemical plants. The exact material substitutions should be confirmed with us. It remains a double-acting, JIS-standard round-body mini cylinder with a SUS304 stainless barrel and riveted aluminium covers.
At 0.5 MPa this 25mm bore delivers 245.3 N push and 206.1 N pull, rising to 343.4 N push at 0.7 MPa. The variable air cushion at both ends, set by a needle, soaks up end-of-stroke shock at high speed. For the same bore and stroke the body is shorter than an ISO 6432 cylinder, saving mounting length. A safe working load of about 147 N is reasonable, or it lifts about 12.5 kg vertically with a 2:1 margin. Port is 1/8".

Where the Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X125SCM Is Used
Ammonia Handling
Copper-free build suits ammonia refrigeration or processing lines where copper alloys corrode. 245.3 N push at 0.5 MPa moves dampers or valves in a compact envelope.
Battery Assembly
Copper-prohibited zones in battery plants benefit from the B52 prefix. The 25mm bore with 125mm stroke actuates light clamps or indexing pins at up to 800 mm/s, with the cushion softening the stop.
High-Speed Sorting
At 30-800 mm/s, the variable cushion at both ends lets you tune deceleration on a 125mm stroke, pushing 245.3 N to divert small parts without shock or noise.
Is the Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X125SCM the Right Cylinder?
For lighter duty, the MFC20 at 157 N push @0.5 MPa saves space and cost. For more force, the MFC32 at 402.2 N push @0.5 MPa is the next step up. The variable cushion is essential when running high speeds or moving heavy loads to prevent harsh impacts. This cylinder does not hold position on air loss; the piston drifts, so use an external rod lock or pilot check valve for held loads. The -S magnet enables CMSG, DMSG, or EMSG switches. The CM round-end back cover is fitted. Mount with LB foot, FA flange, SDB pivot, 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-MFC25X125SCM FAQ
At 0.5 MPa: push 245.3 N, pull 206.1 N. At 0.7 MPa: push 343.4 N, pull 288.5 N. Theoretical max is 50 kgf at 1.0 MPa. The 25mm bore has a 10mm rod, M10x1.25 thread, and 1/8" port.
B52- is AirTAC's copper-free (copper-prohibited) build of the MFC25X125SCM, for lines where copper alloys are banned. Confirm exact material substitutions with us. The variable air cushion at both ends, set by a needle, decelerates the piston near stroke end to cut shock and noise. It is not a lock or brake.
