About the Airtac SE63 Standard Cylinder SE63X520
The AirTAC SE63X520 is a double-acting single-rod ISO 15552 profile cylinder, engineered to deliver a robust 1559 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a highly compact, corrosion-resistant body that mounts flush against machine frames without snagging on adjacent tooling.
This 63 mm bore unit travels a 520 mm stroke and features field-adjustable pneumatic cushioning at both ends. By turning a recessed cushion screw, technicians can precisely tune end-of-stroke deceleration to absorb hard impacts at high speeds. Note that this specific SKU lacks a built-in piston magnet, meaning it is not wired for AirTAC CMSE or DMSE position sensing out of the box.

Where the Airtac SE63 Standard Cylinder SE63X520 Is Used
Corrugated Box Erectors
Provides the 1559 N push force and 520 mm stroke needed to erect and fold large corrugated cardboard blanks in high-speed packaging lines.
Pallet Diverters
Strokes 520 mm to push heavy pallets sideways onto secondary conveyor tracks, utilizing the full travel without tie-rod interference.
CNC Lathe Bar Feeders
Feeds raw bar stock through the spindle over a 520 mm cycle, benefiting from the adjustable end cushions to prevent stock whip on retraction.
Is the Airtac SE63 Standard Cylinder SE63X520 the Right Cylinder?
Generating 1559 N of push force at 0.5 MPa, this 63 mm bore sits comfortably between the 50 mm bore (982 N push) and the 80 mm bore (2513 N push), allowing you to step down for lighter clamping or up for heavier lifting. Because this is a double-acting cylinder, it relies on continuous air pressure to hold a load; if air is lost or the valve is centered, the piston will drift and fail to maintain position. For safety-critical holding, consider the BSE rod-lock variant.
At 520 mm of travel, the unsupported piston rod is highly susceptible to bending under side loads, which can rapidly wear the rod bearing and seals. For any application imposing lateral stress, an external guide rail must be used to carry the load. When retrofitting, this profile cylinder is dimensionally interchangeable per ISO 15552, matching standard mounting centers and PT3/8 porting for seamless hardware swaps.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
