The AirTAC Airtac SC40 Standard Cylinder SC40X670S is a genuine double-acting standard air cylinder with a Ø40mm bore and 670mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X670S is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and a substantial 670 mm stroke, this model is built for applications needing extended linear reach combined with moderate force. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the tie-rod construction keeps the overall body length compact at just 142 mm plus stroke.
The integrated -S magnet allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for precise, non-contact position sensing. This makes the SC40X670S a practical choice for automated machinery where end-of-stroke confirmation is required without external flags or brackets. It operates on filtered air from 0.15 to 1.0 MPa and uses standard PT1/4 ports with an M12x1.25 rod thread.

Moves components 670 mm between conveyor lines or workstations, with sensor feedback confirming full extension and retraction for reliable automation handshakes.
Extends a dispensing head across a wide panel or assembly. The built-in magnet enables multi-position sensing to vary the dispense pattern without changing hard stops.
Operates a long-throw diverter gate or pushes totes onto a sortation lane. The adjustable cushion absorbs the inertia of the moving gate at the end of the 670 mm travel.
For a step up in force, the 50 mm bore SC50 series provides 982 N at 0.5 MPa. If a shorter, more rigid stroke is acceptable, the 40 mm bore's standard strokes top out at 1200 mm, so this 670 mm unit is well within the standard range. At this stroke length, avoid direct side loading on the unsupported rod; use an external linear guide or rod-alignment coupler to prevent bending stress on the rod bearing and premature seal wear. When replacing, match bore, stroke, PT1/4 port thread, the built-in magnet (-S), and the basic mounting style.
Quick checklist
At 0.5 MPa, the push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes, provided the original is a 40 mm bore, 670 mm stroke, tie-rod cylinder with PT1/4 ports, basic mounting, and a magnetic piston for sensors. This is not an ISO 15552 cylinder, so it is dimensionally shorter than a comparable ISO profile unit and is not a drop-in replacement for one.
