The AirTAC SC50 Standard Cylinder SC50X5 is a genuine double-acting standard air cylinder with a Ø50mm bore and 5mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X5 is a compact-stroke member of the AirTAC SC tie-rod family, pairing a 50 mm bore with a 5 mm stroke for precise short-travel positioning. Its 20 mm diameter piston rod and 21 mm adjustable air cushion deliver controlled end-of-stroke deceleration even in rapid cycling, while the PT1/4 ports keep flow paths compact.
At 0.5 MPa this double-acting cylinder develops 982 N pushing force, rising to 1767 N at 0.9 MPa—enough for clamping, ejecting, or short-stroke pressing tasks. The body length A is 150 mm, giving a total extended length of just 155 mm, which fits easily into tight machine envelopes.

The 5 mm stroke and 982 N force at 0.5 MPa make this cylinder ideal for pneumatic toggle clamps and work-holding fixtures where a short, powerful push locks parts for machining or assembly.
Delivers up to 1767 N at 0.9 MPa for light press-fit, staking, or crimping operations. The 20 mm rod and adjustable cushion protect tooling from impact damage during high-cycle runs.
Used as a pneumatic stop gate on conveyors, the SC50X5 extends quickly to halt or divert small pallets and totes, then retracts fully into its 155 mm extended envelope.
Choose the SC50X5 when you need high force in a very short linear stroke—typical for clamping fixtures, precision stops, or stamping dies. If the 982 N push at 0.5 MPa is insufficient, stepping up to the 63 mm bore (SC63 series) raises push force to 1559 N at the same pressure; for a lighter, faster actuator, the 40 mm bore (SC40) provides 628 N.
For replacement, match five points: 50 mm bore, 5 mm stroke, PT1/4 port thread, basic (no accessory) mounting, and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder of the same bore and stroke, so mounting dimensions and tie-rod spacing differ. Replace only with another AirTAC SC50 cylinder matching bore, stroke, PT1/4 ports, and basic mounting.
