The AirTAC Airtac SC40 Standard Cylinder SC40X160TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 160mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X160TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa, ideal for medium-duty actuation where a compact tie-rod design is preferred. With a 40 mm bore and 160 mm stroke, this model uses a 16 mm diameter piston rod and PT1/4 ports, providing a balanced combination of force and speed within the 30-800 mm/s range.
This variant is factory-configured with a centre trunnion (TC) mount, including the TCM1 bracket (order code F-SC40TC), allowing the cylinder to pivot during operation. The adjustable air cushion at each end absorbs impact at 21 mm from stroke end, protecting the end caps and reducing noise in cycling applications.

The centre trunnion mount allows the cylinder body to swing, making it suitable for actuating diverter gates on conveyor lines where the cylinder must pivot as it extends.
Delivers 628 N at 0.5 MPa for secure workpiece clamping in machining or welding fixtures, with adjustable cushioning to prevent impact marks on delicate assemblies.
Used to control chutes or levers on planting and harvesting equipment, where the TPU seals handle standard outdoor temperature swings from -20 to +70 °C reliably.
Choose the SC40 when your application needs roughly 628 N of push force at standard shop air; if you require more force, stepping up to the SC50 bore provides 982 N at the same pressure. For strokes of 160 mm and above, ensure the 16 mm rod is adequately supported against side loads—consider an external guide rail if the load is not purely axial.
This cylinder is a direct replacement for another AirTAC SC40 tie-rod unit with matching 160 mm stroke, PT port thread, and centre trunnion mounting. For drop-in compatibility, verify the bore, stroke, port size, and that the pivot point aligns with the TC trunnion position.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes, the TC suffix means the cylinder is supplied with the centre trunnion and the matching TCM1 trunnion bracket. The complete accessory code for this assembly is F-SC40TC.
