The AirTAC Airtac SC40 Standard Cylinder SC40X225TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 225mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X225TC is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 225 mm stroke. At 0.5 MPa it generates 628 N pushing force and 528 N pulling force, rising to 1130 N push at 0.9 MPa, making it a capable mid-range actuator for general automation.
This model is factory-configured with a TC centre trunnion mount (supplied with TCM1 bracket, accessory code F-SC40TC), allowing the cylinder to pivot during operation for swinging or articulating loads. The 16 mm diameter piston rod, PT1/4 ports, and 21 mm adjustable air cushion at each end provide reliable deceleration and straightforward pneumatic connection.

The 225 mm stroke and centre trunnion mount let the cylinder pivot to swing a diverter gate, sorting packages or parts on a conveyor line with a 628 N push force at 0.5 MPa.
Delivers consistent clamping force for machining or welding fixtures. The adjustable cushion absorbs impact at stroke end, protecting the fixture and workpiece.
Operates chute controls or bin gates in dusty environments. The TPU seals and tie-rod construction offer reliable service with filtered compressed air.
Select the SC40 when your application needs up to 628 N of push force at standard shop air; if you require more, stepping up to the 50 mm bore delivers 982 N at the same 0.5 MPa. For this 225 mm stroke, the rod is well supported within the standard stroke range, but always check that the load is guided and side forces are minimised to protect the rod bearing.
When replacing an existing cylinder, match five points to ensure drop-in compatibility: 40 mm bore, 225 mm stroke, PT1/4 port thread, TC centre trunnion mounting, and confirm whether a magnet is needed (this model has no built-in magnet). The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder provides 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. Only replace with another AirTAC SC tie-rod cylinder matching the 40 mm bore, 225 mm stroke, PT1/4 port, and TC trunnion mount.
