About the Airtac SC40 Standard Cylinder SC40X150TC
The SC40X150TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 150 mm stroke and a 16 mm diameter piston rod, it suits medium-duty linear actuation tasks where compact tie-rod construction is preferred.
This model is factory-configured with a TC centre trunnion mount, supplied with the TCM1 bracket (order code F-SC40TC), allowing the cylinder to pivot during operation. The adjustable air cushion decelerates the piston smoothly at end of stroke, and the PT1/4 port threads ensure straightforward pneumatic connections.

Where the Airtac SC40 Standard Cylinder SC40X150TC Is Used
Part Diverter Gates
The 150 mm stroke and pivoting trunnion mount make this cylinder suitable for actuating diverter gates on packaging conveyors, where the body needs to swing as the gate opens and closes.
Clamping Fixtures
Delivering 1130 N at 0.9 MPa, the SC40X150TC provides consistent clamping force for machining fixtures, holding workpieces securely during milling or drilling operations.
Hopper Door Actuation
The centre trunnion mount allows this cylinder to pivot when opening and closing hopper discharge doors on agricultural dosing equipment, handling the repetitive cycling reliably.
Is the Airtac SC40 Standard Cylinder SC40X150TC the Right Cylinder?
For a step up in force, the SC50 series provides 982 N at 0.5 MPa, while the SC32 offers 402 N for lighter tasks. The TC trunnion mount is ideal for applications where the cylinder body must swing, but ensure the pivot axis is aligned correctly to avoid binding. For strokes over 300 mm on this 16 mm rod, consider an external guide to protect against side-load bending.
When replacing an existing cylinder, match these five points exactly: 40 mm bore, 150 mm stroke, PT1/4 port thread, TC centre trunnion mounting, and the absence of a built-in magnet. The SC40X150TC is a non-ISO tie-rod cylinder; its shorter body length (A=142 mm) means it is not dimensionally interchangeable with ISO 15552 profiles.
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 SC40 Standard Cylinder SC40X150TC FAQ
At 0.7 MPa operating pressure, the SC40 bore generates 879 N of push force. The pull force on the retract stroke is 528 N at 0.5 MPa due to the 16 mm rod reducing the effective piston area.
This specific model (SC40X150TC) does not have the -S magnet suffix, so it lacks the built-in magnetic piston ring required for CMSG/DMSG/EMSG sensors. For sensor compatibility, order the SC40X150STC variant which includes the magnet.
