About the Airtac SC50 Standard Cylinder SC50X1650S
The AirTAC SC50X1650 is a double-acting tie-rod cylinder with a 50 mm bore and an extended 1650 mm stroke, built for applications that need a long linear reach from a compact barrel cross-section. With a 20 mm diameter piston rod and an adjustable air cushion of 21 mm, it delivers a push force of 982 N at 0.5 MPa and rises to 1767 N at the maximum operating pressure of 0.9 MPa.
Because the 1650 mm stroke exceeds the standard maximum of 1200 mm for the 50 mm bore, this is a non-standard, made-to-order configuration. The body length A is 150 mm, giving a total extended length of approximately 1800 mm. It uses PT1/4 ports and an M16x1.5 rod thread, and operates on filtered air from 0.15 to 1.0 MPa in a -20 to +70 °C temperature range with its default TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X1650S Is Used
Long-Reach Material Pushing
Extends 1650 mm to push bins or pallets across wide conveyor sections, where the 50 mm bore provides sufficient force without oversizing the actuator footprint.
Vertical Panel Lifting
Raises large access panels or machine guards over a long vertical stroke, using the 982 N push at 0.5 MPa to handle moderate panel weights smoothly.
Extended Tool Positioning
Positions welding torches or spray nozzles across wide workpieces, where the 1650 mm reach eliminates the need for complex multi-stage linear slides.
Is the Airtac SC50 Standard Cylinder SC50X1650S the Right Cylinder?
Select the SC50X1650 when your application needs a 50 mm bore force class and a stroke beyond the standard 1200 mm limit. For a step up in force, the SC63 bore provides 1559 N at 0.5 MPa; for a shorter standard stroke with the same bore, the SC50X1200 is the maximum off-the-shelf option. At 1650 mm, the unsupported rod length is significant—external guides or a guided cylinder are strongly recommended to prevent rod bending and bearing wear under side load.
When replacing an existing unit, match five points exactly: 50 mm bore, 1650 mm stroke, PT1/4 port thread, basic mounting (no integral bracket), and the absence of a magnet. This ensures dimensional and performance interchangeability with another AirTAC SC50 tie-rod cylinder.
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 SC50X1650S FAQ
At 0.5 MPa (5 bar) the cylinder produces 982 N pushing and 825 N pulling. 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.
No. The maximum standard stroke for the SC50 bore is 1200 mm. The 1650 mm stroke is a non-standard, made-to-order configuration. For such a long stroke, an external guide or rod support is essential to protect the rod bearing from side-load bending moments.
