The AirTAC SC50 Standard Cylinder SC50X625 is a genuine double-acting standard air cylinder with a Ø50mm bore and 625mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X625 is a double-acting tie-rod cylinder engineered for applications requiring an extended 625 mm stroke from a 50 mm bore. At 0.5 MPa air pressure it generates 982 N of push force and 825 N on the pull stroke, while at the maximum operating pressure of 0.9 MPa the push thrust reaches 1767 N.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 pneumatic ports. The adjustable air cushion at each end provides 21 mm of deceleration travel, and the compact body length A of 150 mm keeps the overall extended dimension to 775 mm. Because the 625 mm stroke exceeds the standard maximum of 1200 mm for bore 50, this is a non-standard, made-to-order configuration.

The 625 mm stroke moves components between widely spaced conveyor stations or indexing tables, with 982 N of push force at 0.5 MPa handling moderate transfer loads.
Ideal for jigs that require a long retraction to clear large workpieces, the SC50X625 provides consistent double-acting clamping force up to 1767 N at 0.9 MPa.
Operates sorting gates or pusher arms in material handling systems where a 625 mm linear sweep is needed, with adjustable cushioning to soften end-of-stroke impact.
Select the SC50X625 when your linear motion task needs a 625 mm stroke and the force budget aligns with 982 N at 0.5 MPa (push). If the load demands more thrust, stepping up to the 63 mm bore delivers 1559 N at the same pressure; if a shorter, more rigid assembly is acceptable, the 40 mm bore offers 628 N in a lighter package. For strokes of 300 mm or longer, always evaluate side-loading on the 20 mm rod—an external linear guide or a guided cylinder variant is recommended to prevent rod-bearing bending and premature seal wear.
When replacing an existing cylinder, match five key attributes: 50 mm bore, 625 mm stroke, PT1/4 port thread, the specific mounting accessory (this basic model has no bracket), and the absence of a magnet. The SC tie-rod design is shorter than an ISO 15552 cylinder, so direct dimensional interchangeability with ISO 15552 profiles is not guaranteed.
Quick checklist
At 0.5 MPa the cylinder provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push, and at the maximum operating pressure of 0.9 MPa the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No, the maximum standard stroke for the 50 mm bore SC cylinder is 1200 mm, but the 625 mm intermediate length is a non-standard stroke. It is available as a made-to-order configuration—contact us with the exact model code SC50X625 for a lead-time quotation.
