The AirTAC Airtac SC40 Standard Cylinder SC40X210TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 210mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X210TC is a double-acting tie-rod cylinder with a 40 mm bore and 210 mm stroke, factory-assembled with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa air pressure it generates 628 N of push force and 528 N of pull force, rising to 1130 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 16 mm diameter piston rod with an M12x1.25 male knuckle thread and PT1/4 port connections. The adjustable pneumatic cushion at each end provides a 21 mm deceleration zone, and the body length A is 142 mm. The TC mount ships with the TCM1 trunnion bracket (order F-SC40TC) and allows the cylinder to swing through an arc, making it ideal for clamping or lifting linkages.

The centre trunnion mount lets the cylinder pivot as it actuates a diverter gate on a packaging or sorting conveyor, handling 628 N of push force at standard line pressure.
Ideal for swing-clamp mechanisms in machining centres. The TC mount accommodates the arcing motion, while the 210 mm stroke provides ample clearance for part loading and unloading.
Used in agricultural or construction equipment linkages where the cylinder body must pivot. The 16 mm rod and M12x1.25 thread connect directly to standard rod-end bearings.
For a 40 mm bore, the SC40X210TC sits in the 628 N push class at 0.5 MPa. If your load is lighter and you can accept a smaller envelope, the 32 mm bore delivers 402 N push; for heavier loads, stepping up to the 50 mm bore provides 982 N push at the same pressure. Always match the bore, 210 mm stroke, PT1/4 port thread, centre trunnion mounting, and the absence of a magnet when replacing an existing unit.
At 210 mm stroke, the rod is well-supported within the standard range for this bore (max standard stroke 1200 mm), but any side load must be managed. If the load is not guided externally, consider adding a linear guide or switching to a guided cylinder to prevent rod bending and premature bearing wear.
Quick checklist
At 0.5 MPa (5 bar), the cylinder delivers 628 N pushing and 528 N pulling. At 0.7 MPa it reaches 879 N push, and at the maximum operating pressure of 0.9 MPa it generates 1130 N push. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes, provided the existing unit matches the 40 mm bore, 210 mm stroke, PT1/4 ports, and centre trunnion mounting style. The SC40X210TC includes the TCM1 bracket. Note that the SC series is a tie-rod design and is shorter than an ISO 15552 cylinder, so dimensional interchangeability is not guaranteed.
