The AirTAC SC50 Standard Cylinder SC50X900TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 900mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X900TC is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a substantial 900 mm stroke, it is built on a robust tie-rod construction that is shorter than a typical ISO 15552 profile, making it suitable for installations where space is constrained but high force is still required.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (part code F-SC50TC), allowing the cylinder to pivot during operation to accommodate angular motion. The 20 mm diameter piston rod and PT1/4 port ensure efficient airflow, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly, protecting the end caps from impact at the end of the 900 mm travel.

The centre trunnion mount allows the SC50X900TC to swing freely, making it ideal for actuating diverter gates on long conveyor systems where a 900 mm stroke is needed to fully open or close a material path.
Delivers a controlled 1767 N clamping force at 0.9 MPa to hold large workpieces securely. The long 900 mm stroke retracts the clamp completely clear for easy part loading and unloading in robotic welding cells.
Provides reliable pneumatic power for adjusting the angle of tillage tools or sprayer booms. The trunnion mount handles the pivoting action, while the 50 mm bore offers sufficient force to manage heavy attachments in dusty conditions.
For applications requiring a 50 mm bore, the SC50X900TC provides a balanced force profile. If your load demands more force, stepping up to the 63 mm bore (SC63) increases the push force to 1559 N at 0.5 MPa. Conversely, if 982 N is excessive, the 40 mm bore (SC40) offers 628 N at the same pressure. Always match the bore, stroke, port thread (PT), mounting accessory (TC centre trunnion), and magnet option when replacing an existing unit.
With a stroke of 900 mm, the piston rod is extended significantly. Long, unsupported strokes are susceptible to bending under side loads, which can damage the rod bearing and seals. It is critical to ensure the load is guided externally, or to use a guided cylinder assembly, to prevent any radial force from acting on the rod.
Quick checklist
At the standard operating pressure of 0.7 MPa, this 50 mm bore cylinder generates a theoretical push force of 1374 N and a pull force of 825 N. The maximum force at 0.9 MPa is 1767 N push.
The SC50X900TC has a 20 mm diameter rod that, when fully extended to 900 mm, must not be subjected to side (radial) loads. To prevent bending and premature seal wear, you must guide the load on external rails or linear bearings. The centre trunnion mount handles pivoting motion but does not support the rod against side forces.
