About the Airtac SC50 Standard Cylinder SC50X1500STC
The AirTAC SC50X1500STC is a double-acting single-rod pneumatic cylinder with a 50 mm bore and an extended 1500 mm stroke—this is a non-standard length exceeding the 1200 mm maximum standard stroke for bore 50, so it is built to order. It delivers 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, driven through a 20 mm diameter piston rod with an M16x1.5 male thread.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel, and a centre trunnion mount (-TC suffix) supplied with the TCM1 bracket (order code F-SC50TC). The trunnion allows the cylinder to pivot during operation, ideal for swinging loads. Seals are standard TPU for a -20 to +70 °C range, and ports are PT1/4 with an adjustable air cushion of 21 mm at each end.

Where the Airtac SC50 Standard Cylinder SC50X1500STC Is Used
Long-Reach Sorting Gates
The 1500 mm stroke and centre-trunnion pivot make this cylinder suitable for long-throw diverter gates on wide conveyors, where the magnet sensors confirm open/closed position at each end of travel.
Timber Frame Clamping
Used in woodworking assembly jigs to clamp large frames, the adjustable cushion decelerates the 20 mm rod smoothly at 1500 mm extension, while the trunnion mount absorbs minor misalignment as the clamp closes.
Greenhouse Vent Actuators
Deploys large vent panels in commercial greenhouses. The built-in magnet allows position feedback to a control system, and the non-standard long stroke provides the wide opening angle needed for passive cooling.
Is the Airtac SC50 Standard Cylinder SC50X1500STC the Right Cylinder?
Choose the SC50 bore when your application needs around 982 N of force at standard plant air pressure (0.5 MPa). If you require more force, stepping up to the SC63 delivers 1559 N at the same pressure; for a lighter, more compact solution, the SC40 provides 628 N. Because this cylinder has a very long 1500 mm stroke, the 20 mm rod is susceptible to bending under side loads—always use an external guide rail or rod-alignment coupler to prevent rod bearing damage and ensure straight-line motion.
For direct replacement, match five key points: bore (50 mm), stroke (1500 mm), port thread (PT1/4), the centre trunnion mount with magnet (TC + -S), and the tie-rod body style. This SC model is shorter than an ISO 15552 cylinder and is not dimensionally interchangeable with profile-barrel types.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC50 Standard Cylinder SC50X1500STC FAQ
At 0.7 MPa operating pressure, the 50 mm bore generates 1374 N of push force on extension and 825 N of pull force on retraction. The maximum push force at 0.9 MPa is 1767 N.
The 1500 mm stroke is non-standard for the 50 mm bore (max standard is 1200 mm), so this is a made-to-order item. The -TC suffix means the cylinder comes with the centre trunnion pivot and the matching TCM1 mounting bracket (F-SC50TC) included.
