About the Airtac SC50 Standard Cylinder SC50X1020SH
The AirTAC SC50X1020SH is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa, ideal for long linear movements in hot environments. This model combines a 50 mm bore with an extra-long 1020 mm stroke, a 20 mm diameter piston rod, and Viton (FKM) seals that shift the operating temperature range to 0–150 °C.
A built-in magnet (indicated by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The adjustable air cushion at each end decelerates the piston over 21 mm to soften impact, protecting the cylinder during high-cycle operation. As a non-standard stroke exceeding the 1200 mm maximum for this bore, this unit is made-to-order.

Where the Airtac SC50 Standard Cylinder SC50X1020SH Is Used
High-Temperature Material Handling
Operates reliably in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C, using Viton seals to maintain consistent 982 N push force at 0.5 MPa.
Long-Stroke Part Transfer
The 1020 mm stroke moves parts between distant stations on assembly lines. The built-in magnet enables sensor-based position verification at both ends of the extended travel.
Sterilization Equipment Actuation
Withstands aggressive cleaning agents and high-temperature steam sterilization cycles in pharmaceutical and food processing machinery, providing 1767 N of force at 0.9 MPa.
Is the Airtac SC50 Standard Cylinder SC50X1020SH the Right Cylinder?
Select the SC50X1020SH when your application requires a 50 mm bore with a precise 1020 mm stroke and high-temperature resistance. For higher force at the same pressure, stepping up to a 63 mm bore provides 1559 N of push force at 0.5 MPa. For a shorter standard stroke, the SC50X1000 is an alternative.
For strokes of this length, the 20 mm rod is susceptible to bending under side loads. An external guide system or a self-guided cylinder is strongly recommended to prevent rod bearing damage and ensure linear motion stability. When replacing this cylinder, match five key points: 50 mm bore, 1020 mm stroke, PT port thread, the -S magnet for sensor compatibility, and the -H Viton seal material for high-temperature operation.
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 SC50X1020SH FAQ
At the standard operating pressure of 0.7 MPa, this 50 mm bore cylinder provides 1374 N of push force and 825 N of pull force. The theoretical maximum push force at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, PT ports, magnet, and Viton seals.
