The AirTAC SC50 Standard Cylinder SC50X890S is a genuine double-acting standard air cylinder with a Ø50mm bore and 890mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X890S is a double-acting single-rod pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with an 890 mm stroke. This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless end-of-stroke or mid-position detection. At 0.5 MPa it provides 982 N of push force and 825 N of pull force, rising to 1767 N push at the maximum operating pressure of 0.9 MPa.
The 20 mm diameter piston rod and PT1/4 ports suit general automation tasks requiring moderate force and long travel. The cylinder body length A is 150 mm, giving a total extended length of approximately 1040 mm. Adjustable pneumatic cushioning at both ends decelerates the piston over 21 mm to reduce impact energy. Operating temperature range is -20 to +70 °C with the standard TPU/NBR seals, and the speed range is 30-800 mm/s. This is a genuine AirTAC SC cylinder, factory-tested to 1.5 MPa proof pressure.

The 890 mm stroke moves components between distant conveyor stations. The built-in magnet enables sensor confirmation at both ends of travel for automated sequencing.
Provides the long, steady linear motion needed for applying adhesive beads or sealant across large panels, with magnetic sensors confirming stroke completion.
Operates tall hopper doors or lift gates in agricultural and material handling equipment, using the 982 N push force at standard shop air pressure.
The SC50X890S is ideal when you need a 50 mm bore with integrated magnetic piston sensing for a long 890 mm stroke. If your force requirement is lower, stepping down to a 40 mm bore (628 N push at 0.5 MPa) can reduce air consumption; for higher force, the 63 mm bore delivers 1559 N push at the same pressure. Always match replacements on five points: bore, stroke, port thread (PT), mounting accessory, and the magnet option (-S).
With an 890 mm stroke, the unsupported rod is susceptible to bending under side loads. For this stroke length, use an external linear guide or a guided cylinder assembly to protect the rod bearing and ensure reliable operation. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder produces 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N push force.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be mounted directly on the tie-rod barrel for contactless position sensing without any modification.
