About the Airtac SC50 Standard Cylinder SC50X1750STC
The AirTAC SC50X1750STC is a double-acting single-rod tie-rod cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 20 mm diameter rod and M16x1.5 rod thread, this model is built for robust linear actuation tasks requiring a 1750 mm stroke.
This cylinder features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC suffix) supplied with the TCM1 bracket for pivoting applications. The 1750 mm stroke exceeds the standard maximum of 1200 mm for 50 mm bore, making this a non-standard, made-to-order configuration.

Where the Airtac SC50 Standard Cylinder SC50X1750STC Is Used
Long-Reach Material Handling
Ideal for pushing or pulling bins and totes across wide conveyor gaps in automated warehouses, using the 1750 mm stroke and trunnion pivot.
Automated Welding Fixtures
Positions welding torches or clamps with a long linear sweep, where the centre trunnion mount allows the cylinder body to swing into position.
Agricultural Machinery
Controls large gates or chutes on seed drills and harvesters, with the magnet sensors confirming open/closed status in dusty conditions.
Is the Airtac SC50 Standard Cylinder SC50X1750STC the Right Cylinder?
Selecting the SC50X1750STC means matching a 50 mm bore to a 1750 mm stroke with magnet and centre trunnion mounting. If your force requirement is lower, stepping down to a 40 mm bore provides 628 N at 0.5 MPa; for higher force, the 63 mm bore delivers 1559 N. At this extended stroke length, the 20 mm rod is susceptible to bending under side loads—always use an external guide or linear rail to protect the rod bearings and ensure reliable operation. For replacement, match bore, stroke, PT port thread, centre trunnion mount, and the integrated magnet sensor capability.
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 SC50X1750STC FAQ
At 0.5 MPa, it pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force is 1767 N.
No, 1750 mm exceeds the standard maximum of 1200 mm for a 50 mm bore. It is a non-standard stroke, manufactured to order with a longer body and rod.
