The AirTAC Airtac SC50 Standard Cylinder SC50X950LB 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 AirTAC SC50X950LB is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 50 mm bore and 950 mm stroke suit long-travel linear applications where a robust, serviceable cylinder is needed. The included LB foot mounting (F-SC50LB) provides stable axial support along the barrel.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 pneumatic ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at end-of-stroke. With a body length A of 150 mm, the total extended length reaches 1100 mm, requiring attention to rod alignment and side-load management.

The 950 mm stroke and 982 N force at 0.5 MPa efficiently push boxes or pallets across wide conveyor transfer stations, with the LB foot mount securing the cylinder to the frame.
Delivers consistent, long-reach linear motion for adhesive bead application or sealant dispensing gantries, where the adjustable cushion protects the tooling at stroke end.
Operates tall lift gates or hopper doors in agricultural or bulk-handling equipment, using the 1767 N force at 0.9 MPa to manage heavy vertical panels.
For applications needing slightly less force, the 40 mm bore SC40 series provides 628 N at 0.5 MPa. If higher force is required, step up to the SC63 series delivering 1559 N at the same pressure. At a 950 mm stroke, the 20 mm rod is susceptible to bending under side loads; use an external guide rail or a guided cylinder if the load is not perfectly axial. When replacing, match five points: 50 mm bore, 950 mm stroke, PT1/4 ports, LB foot mount (F-SC50LB), and the standard non-magnetic piston.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. 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.
For strokes of 300 mm or more, side loads can cause the 20 mm rod to bend or wear the bearing prematurely. Always guide the load externally with a linear rail or rod guide. If side loads are unavoidable, consider a guided cylinder or an external guide system instead of relying on the cylinder's rod bearing alone.
