The AirTAC Airtac SC50 Standard Cylinder SC50X950SN is a genuine double-acting standard air cylinder with a Ø50mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X950SN is a double-acting pneumatic cylinder delivering 982 N push and 825 N pull at 0.5 MPa, rising to 1767 N push at the 0.9 MPa maximum operating pressure. Its 950 mm stroke is close to the 1200 mm maximum standard limit for the 50 mm bore, making it a long-stroke workhorse for extended linear movements.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel, and is fitted with NBR (nitrile) seals (-N suffix) for standard temperature operation from -20 to +70 °C. The 20 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration for the 200 kgf class actuator.

The 950 mm stroke moves components between distant conveyor stations. NBR seals handle lubricated plant air, and the magnet allows end-of-stroke sensing for automated sequencing.
Provides a steady 982 N push at 0.5 MPa to drive a dispensing head along a long linear path. The adjustable cushion protects the adhesive pattern from vibration at stroke end.
Extends a stop gate across a log chain with 1767 N of force at 0.9 MPa. The 20 mm rod and NBR seals are robust for dusty environments when the rod is protected by a wiper.
For applications needing more force, stepping up to the 63 mm bore provides 1559 N push at 0.5 MPa, while a 40 mm bore offers 628 N for lighter, faster cycles. At 950 mm stroke, the unsupported rod length is significant; any side load will create a bending moment on the rod bearing. Use an external linear guide or rod-alignment coupler to protect the rod and bearing from premature wear.
When replacing an existing cylinder, match five key points: 50 mm bore, 950 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the NBR seal material. The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder produces 982 N pushing force and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
Yes. The -S suffix indicates a built-in magnet in the piston, allowing AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the cylinder's tie-rod barrel for non-contact position detection.
