The AirTAC Airtac SC40 Standard Cylinder SC40X300TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 300mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X300TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore houses a 16 mm diameter piston rod with M12x1.25 male threads, and the 300 mm stroke is well within the 1200 mm maximum standard stroke for this bore size.
This model is configured with a TC centre trunnion mount (part code F-SC40TC), supplied together with the TCM1 bracket, allowing the cylinder to pivot during operation. The adjustable air cushion at each end, with a 21 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact. Ports are PT1/4, and the body length A is 142 mm, giving a total extended length of approximately 442 mm.

The 300 mm stroke and pivoting trunnion mount suit conveyor diverter gates, where the cylinder swings to redirect packages or components between lanes without binding.
With 1130 N of force at 0.9 MPa, this cylinder provides robust clamping for medium-duty CNC fixtures and welding jigs, holding workpieces securely during machining or assembly.
The centre trunnion mount allows the cylinder body to pivot, making it ideal for driving mechanical linkages, levers, and toggle mechanisms that move through an arc.
Choose the SC40 bore when your application needs between 528 N (pull) and 628 N (push) at 0.5 MPa. If you require more force, step up to the SC50 which provides 982 N push at the same pressure; for a lighter, more compact solution, the SC32 offers 402 N push. Always match replacement cylinders on five points: bore (40 mm), stroke (300 mm), port thread (PT), mounting accessory (TC centre trunnion), and magnet option (none here).
At a 300 mm stroke, ensure the load is guided externally if any side forces are present. An unsupported 16 mm rod at full extension can experience bending stress under lateral loads, so use external guide rails or a guided cylinder configuration to protect the rod bearings and seals.
Quick checklist
At the standard operating pressure of 0.5 MPa, the cylinder produces 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.
Match the bore (40 mm), stroke (300 mm), and ensure the replacement has a TC centre trunnion mount with the TCM1 bracket. The port thread must be PT1/4. This model does not have a built-in magnet, so sensors require external mounting brackets if needed.
