Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X160SU
The AirTAC Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X160SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 160mm 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-MFC25X160SU
The B52- prefix marks AirTAC's copper-free build of the MFC25X160SU, designed for lines where copper and copper alloys are not permitted, such as ammonia systems and some battery, electronics, and chemical plants. This double-acting mini cylinder delivers 245.3 N push and 206.1 N pull at 0.5 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa. Its JIS-standard round-body construction uses a SUS304 stainless barrel with riveted aluminium covers, making it shorter than an ISO 6432 cylinder for the same bore and stroke.
A variable air cushion at both ends lets you adjust a needle to decelerate the piston smoothly at high speed, protecting loads and cutting noise. The -S suffix means a built-in piston magnet is present, enabling CMSG, DMSG, or EMSG sensors. The U back cover provides a flat-end rear style. With a safe working load of about 147 N and vertical lift capacity of roughly 12.5 kg with a 2:1 margin, this cylinder suits moderate-force automation tasks.

Where the Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X160SU Is Used
Battery Assembly Stops
Position light battery components with 245.3 N push force; the variable cushion prevents jarring at stroke end, protecting sensitive cell contacts.
Chemical Dosing Actuator
Copper-free construction suits ammonia-handling lines where copper alloys are prohibited; the stainless barrel resists mild chemical exposure.
High-Speed Labeling Press
Drive labeling heads at up to 800 mm/s; the adjustable air cushion absorbs kinetic energy smoothly, reducing noise and wear on the mechanism.
Is the Airtac B52-MFC Copper-Free Stainless Steel Mini Cylinder B52-MFC25X160SU the Right Cylinder?
Size down to the MFC20 at 157 N push @0.5 MPa if your load is light and space is tight; size up to the MFC32 at 402.2 N push @0.5 MPa if you need substantially more force. The variable cushion is essential when running at high speeds or moving heavy loads that could cause end-of-stroke shock. Remember, this cylinder does not hold position on air loss - the piston drifts. For a held load, use an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot block, or TC trunnion. The -S magnet allows sensor mounting with CMSG, DMSG, or EMSG switches.
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-MFC25X160SU FAQ
At 0.5 MPa, push force is 245.3 N and pull is 206.1 N. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. Theoretical maximum force is 50 kgf at 1.0 MPa. The 1/8" port and M10x1.25 rod thread match the standard MFC25 configuration.
B52- indicates AirTAC's copper-free (copper-prohibited) build of the MFC25X160SU, for applications where copper alloys are not allowed. The variable air cushion at both ends uses a needle valve to control deceleration near stroke end - it smooths high-speed operation but does not lock or hold the load. The -S magnet enables CMSG, DMSG, or EMSG sensors. For exact material substitutions in the copper-free build, please confirm with us.
