About the Airtac SC32 Standard Cylinder SC32X400LB
The AirTAC SC32X400LB is a double-acting single-rod pneumatic cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa). Its 400 mm stroke is well within the 1000 mm maximum standard stroke for the 32 mm bore, making it a ready-to-ship standard configuration.
This model includes the LB foot mount (F-SC32LB) for secure surface installation and features a 12 mm diameter piston rod with an M10x1.25 knuckle thread. The adjustable air cushion, with a 21 mm cushion length, decelerates the piston smoothly at end-of-stroke to reduce impact noise and vibration.

Where the Airtac SC32 Standard Cylinder SC32X400LB Is Used
Small-Part Sorting Gates
Operates lightweight diverter gates on conveyor lines. The 402 N force at 0.5 MPa is ideal for pushing small packages or components onto branch lanes.
Assembly Fixture Clamping
Provides consistent clamping force for jigs and fixtures in electronics or small-parts assembly. The 400 mm stroke allows the actuator to retract fully for clear part loading.
Labeling & Stamping Presses
Drives the pressing action in light-duty hot-stamp or labeling machines. The adjustable cushion protects the tooling by softening the impact at the end of the 400 mm advance.
Is the Airtac SC32 Standard Cylinder SC32X400LB the Right Cylinder?
Choose the SC32X400LB for light automation tasks where a compact 32 mm bore provides sufficient force. If your load requires more thrust, step up to the SC40 series which offers 628 N at 0.5 MPa. For strokes over 300 mm, ensure the rod is not subjected to significant side loads; an external linear guide is recommended to prevent rod bending and premature bearing wear.
This cylinder is a direct replacement for any AirTAC SC32X400 with an LB foot mount. To guarantee a match, confirm five points: 32 mm bore, 400 mm stroke, PT1/8 port thread, LB foot mounting accessory, and the absence of a built-in magnet.
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 SC32 Standard Cylinder SC32X400LB FAQ
At the standard operating pressure of 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N.
This specific model (SC32X400LB) does not have the -S suffix, so it does not include a built-in magnet. To use CMSG/DMSG/EMSG sensors, order the SC32X400-SLB variant which includes the magnet.
