The AirTAC Airtac SC40 Standard Cylinder SC40X230TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 230mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X230TC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 230 mm stroke suit medium-duty linear tasks where a pivoting mount is required. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration at end-of-stroke.
This model is factory-assembled with a centre trunnion (TC) mount, including the TCM1 bracket, allowing the cylinder to pivot during operation. The total extended body length is approximately 372 mm (142 mm body length A + 230 mm stroke). Ports are PT1/4 with an M12x1.25 rod thread, and the standard TPU seals operate reliably from -20 to +70 °C.

The 230 mm stroke and pivoting trunnion mount suit medium-reach diverter gates on packaging lines, operating at standard factory air pressure.
628 N of push force securely holds workpieces in CNC welding jigs, with the adjustable cushion reducing impact at clamp closure.
The tie-rod design and TPU seals handle dusty environments in seed sorting equipment, with the trunnion mount allowing the actuator to follow an arcing linkage.
Choose the SC40 bore when 628 N at 0.5 MPa matches your load; for higher force, step up to the SC50 which provides 982 N at the same pressure. For lighter, compact tasks, the SC32 delivers 402 N. This 230 mm stroke is within the 1200 mm maximum standard stroke for bore 40.
To ensure a correct replacement, match five points: 40 mm bore, 230 mm stroke, PT1/4 port thread, centre trunnion (TC) mount with TCM1 bracket (part F-SC40TC), and confirm no magnet is needed. For strokes over 300 mm, consider an external guide to protect the rod from bending under side load.
Quick checklist
At 0.7 MPa operating pressure, the SC40 bore produces 879 N of push force. The pull force at the same pressure is 528 N, accounting for the 16 mm rod area.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so mounting dimensions are not interchangeable. Only replace with another AirTAC SC40 tie-rod cylinder matching the 230 mm stroke, PT1/4 port, and TC trunnion mount.
