The AirTAC Airtac SC40 Standard Cylinder SC40X365 is a genuine double-acting standard air cylinder with a Ø40mm bore and 365mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X365 is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa, scaling up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and a 365 mm stroke, this model uses a 16 mm diameter piston rod and PT1/4 ports, making it a solid mid-range actuator for industrial automation tasks.
Its tie-rod construction keeps the overall extended length compact at approximately 507 mm (142 mm body length A plus stroke), while the adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length. This cylinder is built with standard TPU seals for reliable operation in a -20 to +70 C temperature range.

Provides the 365 mm stroke needed to fully extend a diverter gate on a conveyor line, directing packages between lanes with the 628 N force at standard plant pressure.
Delivers a controlled 1130 N clamping force at 0.9 MPa to hold workpieces securely during CNC machining or welding operations, with the adjustable cushion preventing part damage.
The long 365 mm stroke is ideal for pushing cartons onto a pallet layer, where the 40 mm bore provides a balanced force-to-speed ratio for consistent, repeatable motion.
For applications needing more force, consider stepping up to the SC50 bore which provides 982 N of push force at 0.5 MPa. If a shorter, more compact solution is acceptable, the SC32 bore offers 402 N at the same pressure. This 365 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore.
When replacing an existing cylinder, ensure a 5-point match: 40 mm bore, 365 mm stroke, PT1/4 port thread, basic mounting (no accessory brackets), and the absence of a built-in magnet. For strokes over 300 mm, be mindful of side loads; the 16 mm rod can experience bending under high lateral forces. An external guide or a guided cylinder is recommended if the load is not perfectly axial.
Quick checklist
At 0.7 MPa operating pressure, the SC40X365 produces a theoretical push force of 879 N and a pull force of 528 N. The maximum push force at 0.9 MPa is 1130 N.
No, this specific model code does not include the -S magnet option. The piston does not have a built-in magnetic ring, so CMSG/DMSG/EMSG sensors cannot be used. For sensor compatibility, order the SC40X365-S variant instead.
