The AirTAC Airtac SC40 Standard Cylinder SC40X70TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 70mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X70TC is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 70 mm stroke suits short linear transfer and clamping tasks where space is limited. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration.
This model includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC40TC), allowing the cylinder body to pivot during operation. It uses PT1/4 ports and a standard TPU seal for a temperature range of -20 to +70 °C.

The centre trunnion mount allows the cylinder to pivot, making it suitable for actuating diverter gates on small conveyor lines.
Delivers 628 N of clamping force at 0.5 MPa for holding workpieces during light machining or assembly operations.
Pivoting action and compact 70 mm stroke suit mechanical linkages on agricultural sorting or packaging equipment.
Choose the SC40 when the 32 mm bore’s 402 N force at 0.5 MPa is insufficient. If you need more force, the SC50 delivers 982 N at the same pressure. The TC trunnion mount is ideal for applications where the cylinder must swing through an arc. For a direct replacement, match the 40 mm bore, 70 mm stroke, PT1/4 port, centre trunnion mounting, and ensure the magnet option matches your sensor setup.
Quick checklist
At 0.7 MPa operating pressure, the 40 mm bore generates 879 N of push force and 528 N of pull force on the retract stroke.
Yes, if the original is a 40 mm bore, 70 mm stroke tie-rod cylinder with a centre trunnion mount and PT1/4 ports. Verify the trunnion pin diameter and position match your existing bracket or use the included TCM1 bracket (F-SC40TC).
