About the Airtac B52-SE Copper-Free ISO Standard Cylinder B52-SE40X350S
The B52-SE40X350S is AirTAC's copper-free (copper-prohibited) build of the SE40X350S, a double-acting single-rod ISO 15552 profile cylinder. The square extruded aluminum barrel has no external tie rods, giving a compact, corrosion-resistant body that mounts flush in tight machine frames. With a 40 mm bore, it delivers 628 N push and 528 N pull at 0.5 MPa, making it a solid mid-range actuator for assembly and light packaging lines.
The B52- prefix marks this as the copper-free version, intended for lines where copper and copper alloys are not permitted, such as ammonia systems or certain battery, electronics, and chemical plants. The exact material substitutions are not listed in our data, so confirm those details with us before ordering. The cylinder includes a built-in magnet (-S) for CMSE reed or DMSE electronic sensors, and the air cushion at both ends is field-adjustable via screw to soften hard stops at speed.

Where the Airtac B52-SE Copper-Free ISO Standard Cylinder B52-SE40X350S Is Used
Battery Cell Assembly Press
In a lithium-ion cell stacking fixture, the 628 N push at 0.5 MPa provides controlled force for pressing separator layers without crushing the electrode stack. The copper-free build prevents galvanic contamination in the clean, chemical-sensitive assembly area.
Ammonia Refrigeration Valve Actuator
For a plant using ammonia-based cooling, this copper-free cylinder actuates a divert valve in the refrigerant line. The 350 mm stroke gives the travel needed to shift the valve spool, while the -S magnet lets a DMSE electronic sensor confirm full extension remotely.
Carton Ejector on Tray Former
On a corrugated tray-forming machine, this cylinder pushes finished cartons off the forming die onto a takeaway conveyor. The 528 N pull at 0.5 MPa retracts the ejector paddle quickly, and the adjustable cushion prevents the paddle from slamming at the end of the 350 mm return stroke.
Is the Airtac B52-SE Copper-Free ISO Standard Cylinder B52-SE40X350S the Right Cylinder?
At 350 mm stroke, this cylinder sits in the mid-range of the 40 mm bore class. If you need more force, step up to the 50 mm bore, which pushes 982 N at 0.5 MPa; if you need less, step down to the 32 mm bore at 402 N push. For this long stroke, consider an external guide to prevent rod bending and side-load wear on the M12x1.25 rod thread.
This is a true ISO 15552 profile cylinder, so it drops into existing mounts designed for other ISO 15552 cylinders. The PT1/4 port matches the 40 mm bore standard. Note that a plain SE does not hold position when air is lost or the valve is centred - the piston drifts. For load holding, look to the BSE rod-lock variant or an external pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac B52-SE Copper-Free ISO Standard Cylinder B52-SE40X350S FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At 0.7 MPa, push increases to 879 N. The maximum push is 128 kgf at 1.0 MPa. These figures are identical to the standard SE40X350S, as the B52- prefix only changes material composition, not dimensions or pneumatic performance.
B52- is AirTAC's copper-free (copper-prohibited) build, used in lines where copper and copper alloys are not allowed, such as ammonia systems or certain battery and chemical plants. It is dimensionally interchangeable with other ISO 15552 cylinders, so it fits standard 40 mm bore mounts. The PT1/4 port and 350 mm stroke are unchanged. Since our data does not specify which parts are substituted or any certification, please confirm the exact material grades and any compliance requirements with us before purchasing.
