The AirTAC SC50 Standard Cylinder SC50X75CB is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75CB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With a 50 mm bore and 75 mm stroke, it uses a 20 mm diameter piston rod with M16x1.5 male threads, making it a robust mid-range actuator for general industrial automation.
This model is configured with a rear double clevis (CB) mounting, part F-SC50CB, which allows the cylinder body to pivot during operation, ideal for applications where the load path is not perfectly linear. The standard PT1/4 ports and adjustable air cushion at both ends ensure smooth, controlled motion across its 30-800 mm/s speed range.

The rear double clevis mount allows the SC50X75CB to pivot freely, making it suitable for actuating linkages on agricultural machinery or construction attachments where the cylinder must follow an arc.
With a push force of 1767 N at 0.9 MPa, this cylinder provides ample power for pneumatic clamping fixtures, light stamping presses, or riveting operations in assembly lines.
The compact 75 mm stroke and pivoting clevis mount are ideal for actuating diverter gates on conveyor systems, reliably sorting packages or materials with a controlled, cushioned motion.
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. If a lower profile is required, the 40 mm bore offers 628 N. The 75 mm stroke is well within the 1200 mm maximum standard stroke for this bore, ensuring standard lead times.
When replacing this cylinder, match five key points: 50 mm bore, 75 mm stroke, PT1/4 port thread, the CB rear double clevis mounting, and the absence of a magnet. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The 'CB' suffix designates a rear double clevis mount (fork). This allows the entire cylinder body to pivot on a pin at the rear cap, which is essential for applications where the attached load moves through an arc. The mounting accessory part code is F-SC50CB.
