The AirTAC Airtac SC Standard Cylinders SC63X175 is a genuine double-acting standard air cylinder with a Ø63mm bore and 175mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC63X175 is a double-acting tie-rod cylinder with a 63 mm bore and 175 mm stroke, sized for mid-duty push and pull work. At 0.5 MPa it develops about 1559 N on extension and 1402 N on retraction, rising to 2182 N at 0.7 MPa and 2805 N at the 0.9 MPa peak operating pressure. The 20 mm rod gives the piston solid column strength at this stroke length.
This model is the basic version: no mounting bracket, TPU seals rated -20 to +70 C, and PT1/4 ports as standard. The adjustable cushion is 28 mm per end, so you can tune deceleration to soften impact at both stroke ends. With a body length A of 153 mm, the fully extended length is roughly 328 mm, keeping the envelope compact in tight machine frames.

With 1559 N of push force at 0.5 MPa, the SC63X175 holds workpieces firmly in machining and assembly fixtures, and the 28 mm cushion damps the clamp impact.
The 175 mm stroke suits conveyor stop-and-divert gates, nudging cartons or bins off a line at up to 800 mm/s with reliable retraction under 1402 N of pull force.
Lift small pallets, chutes or eject parts from dies - the 63 mm bore delivers 2182 N at 0.7 MPa, enough for repetitive vertical lifting in a compact 328 mm extended length.
Choose the SC63X175 when your load needs more than the SC50 can deliver - the 50 mm bore produces only 982 N at 0.5 MPa. If 1559 N is far more than you need, stepping down to the SC50 saves air and money. For heavier duty, the SC80 reaches 2513 N at the same pressure. At 175 mm stroke the rod is well supported, but if your application adds side load, pair the cylinder with an external guide to protect the rod bearing.
Replacing an existing unit? Match all five points: 63 mm bore, 175 mm stroke, PT1/4 port thread, the same mounting accessory, and whether a magnet (-S suffix) is fitted. The SC is a tie-rod cylinder, not an ISO 15552 profile, so confirm the old cylinder is an AirTAC SC or equivalent tie-rod type before ordering.
Quick checklist
At 0.5 MPa the 63 mm bore gives 1559 N extending and 1402 N retracting. At 0.7 MPa push force is 2182 N, and at the maximum operating pressure of 0.9 MPa it reaches 2805 N. Theoretical maximum force at 1.0 MPa is about 318 kgf.
Match five things: the 63 mm bore, the 175 mm stroke, the PT1/4 port thread (or specify G thread with the -G suffix), the mounting arrangement, and whether the old unit has a magnet (-S) for position sensing. The SC is a tie-rod design and is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable with ISO profile cylinders.
