The AirTAC Airtac SC40 Standard Cylinder SC40X158 is a genuine double-acting standard air cylinder with a Ø40mm bore and 158mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X158 is a genuine AirTAC single-rod, double-acting pneumatic cylinder with a 40 mm bore and 158 mm stroke. Operating at 0.5 MPa, it generates a push force of 628 N and a pull force of 528 N, making it suitable for moderate clamping, pressing, and transfer tasks.
This tie-rod cylinder uses a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The body length A is 142 mm, and the adjustable air cushion at each end provides a 21 mm deceleration zone to reduce end-of-stroke impact without locking the piston.

Pushes or lifts components between conveyor lanes or indexing stations with 628 N of force at standard shop air pressure.
Provides controlled insertion force for bearings, bushings, or pins in bench-top assembly fixtures.
Operates a small material gate or diverter flap on a packaging or sorting line, using the 21 mm adjustable cushion for quiet end-of-stroke stopping.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at the same 0.5 MPa pressure. If space is tight and less force is acceptable, the 32 mm bore SC32 delivers 402 N. Always match the bore, 158 mm stroke, PT1/4 port thread, and basic mounting when replacing an existing SC40 cylinder.
At a 158 mm stroke, the rod is well-supported within standard limits, but avoid direct side loads on the rod end. If the load is not guided externally, consider adding an external linear guide to protect the rod bearing and piston seals from premature wear.
Quick checklist
At 0.5 MPa (5 bar) 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 force at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so mounting dimensions and accessories are not interchangeable. It is a direct dimensional match only for another AirTAC SC40 tie-rod cylinder with the same bore, stroke, and port thread.
