About the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X125S
The B04-SC32X125S is an AirTAC double-acting tie-rod cylinder built for construction machinery. The B04- prefix marks it as the construction-machinery dedicated variant of the SC32X125S, meaning it is mechanically identical to the standard model. It delivers a push force of 402 N at 0.5 MPa and 724 N at 0.9 MPa.
Featuring a 32 mm bore and 125 mm stroke, this unit includes a built-in magnet for CMSG/DMSG/EMSG sensors. It uses a PT1/8 port, a 12 mm rod, and has an adjustable cushion length of 21 mm. The body length A is 140 mm, yielding a total extended length of approximately 265 mm.

Where the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X125S Is Used
Excavator Actuation
Drives secondary auxiliary flaps or covers on heavy equipment where a compact 32 mm bore and 125 mm stroke fit tight machinery envelopes.
Concrete Pump Controls
Switches small pneumatic valves or flow diverters in dusty construction environments, utilizing the built-in magnet for position feedback.
Heavy Equipment Latches
Actuates locking pins or access panel latches on cranes and loaders, providing 724 N of thrust at 0.9 MPa operating pressure.
Is the Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X125S the Right Cylinder?
This 32 mm bore provides 402 N of push force at 0.5 MPa. If your heavy-equipment application requires less force, dropping to a smaller bore changes the dynamics significantly, while stepping up to a 40 mm bore increases the push force to 628 N at 0.5 MPa. At 125 mm stroke, side-load stress is moderate but should still be managed with proper rod bearing alignment.
When ordering a replacement for the B04-SC32X125S, match these five points: 32 mm bore, 125 mm stroke, PT1/8 port thread, basic mounting style, and the built-in magnet (-S). This tie-rod cylinder is shorter than an ISO 15552 unit and is not dimensionally interchangeable with that profile.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac B04-SC Construction Machinery Special Standard Cylinder B04-SC32X125S FAQ
The B04- prefix indicates this is an AirTAC construction-machinery dedicated variant. It is mechanically identical to the standard SC32X125S cylinder, offering the same 32 mm bore, 125 mm stroke, and 724 N thrust at 0.9 MPa.
No, the SC series is a double-acting pneumatic cylinder and cannot hold position without live air pressure. The adjustable cushion only decelerates the piston at stroke end; a mechanical lock or external brake is required to hold loads safely.
