The AirTAC SC50 Standard Cylinder SC50X90TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X90TC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a robust mid-range actuator for industrial tasks. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 90 mm stroke, while the included centre trunnion mount allows the cylinder to pivot during operation.
This configuration features a PT1/4 port and an M16x1.5 rod thread, with a compact body length of 150 mm (total extended length approximately 240 mm). As a genuine AirTAC SC tie-rod cylinder, it is shorter than an ISO 15552 profile, so replacement should match another SC series unit with identical bore, stroke, port, and trunnion mounting.

The pivoting action of the TC mount combined with 90 mm of stroke makes this cylinder ideal for actuating diverter gates on packaging conveyors, sorting products between lanes.
Delivers a consistent 982 N clamping force at 0.5 MPa for welding jigs and assembly fixtures, with the trunnion mount allowing the cylinder body to self-align as the clamp closes.
Controls discharge chutes on seed or grain handling equipment. The centre trunnion allows the chute to swing through an arc, directing material flow between different bins.
Select the SC50X90TC when your application requires a pivoting actuator with a push force around 982 N at standard plant pressure. If you need significantly more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa, while the 40 mm bore offers 628 N for lighter, more compact installations.
For replacement, ensure a five-point match: 50 mm bore, 90 mm stroke, PT1/4 port thread, centre trunnion (TC) mount with the TCM1 bracket, and no magnet. The centre trunnion is ideal for swinging loads, but always align the pivot axis precisely to prevent binding. For strokes over 300 mm with this rod diameter, consider an external guide to protect the rod bearing from side loads.
Quick checklist
At 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 reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder, so dimensional interchangeability is not guaranteed. It should only replace another AirTAC SC series cylinder with matching bore, stroke, port thread, and trunnion mounting.
