About the Airtac SE63 Standard Cylinder SE63BX70
The AirTAC SE63BX70 is a double-acting, single-rod ISO 15552 profile cylinder engineered with a 63 mm bore and 70 mm stroke. It delivers a robust 1559 N push force at 0.5 MPa and 2182 N at 0.7 MPa, making it well-suited for mid-weight industrial actuation. This specific SKU features a SUS304 stainless steel rod (code B), providing superior corrosion resistance for washdown or chemically exposed environments.
Unlike traditional tie-rod designs, its square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush on machinery while resisting external contamination. The cylinder integrates field-adjustable air cushioning at both ends, allowing technicians to tune end-of-stroke deceleration via a set screw to eliminate hard mechanical impacts during high-speed cycling.

Where the Airtac SE63 Standard Cylinder SE63BX70 Is Used
Pallet Strapping Press
Drives a strapping head with 1559 N push at 0.5 MPa to tension and seal polyethylene bands around outbound pallets.
Lab Washdown Diverter
The SUS304 stainless steel rod withstands harsh chemical washdowns while actuating a flow diverter valve in pharmaceutical mixing lines.
CNC Chip Conveyor Gate
Utilizes the 70 mm stroke to open and close a metal chip discharge gate on a CNC machining center, tuned by adjustable air cushions.
Is the Airtac SE63 Standard Cylinder SE63BX70 the Right Cylinder?
This 63 mm bore provides 1559 N of push force at 0.5 MPa. If your application requires less energy, the 50 mm bore offers 982 N of push at 0.5 MPa; if you need greater thrust, stepping up to the 80 mm bore yields 2513 N at 0.5 MPa. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered—the piston will drift. For position-holding safety, consider the AirTAC BSE rod lock series or an external pilot-operated check valve. To replace an existing cylinder, match the 63 mm bore, 70 mm stroke, PT3/8 port, and your required ISO 15552 mounting accessory. Note that this SKU lacks a position-sensing magnet; adding an -S suffix enables CMSE reed or DMSE electronic switches.
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.
Airtac SE63 Standard Cylinder SE63BX70 FAQ
At 0.5 MPa, the SE63BX70 provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force is 2182 N. The maximum push force is 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE63BX70 is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders by matching the 63 mm bore, 70 mm stroke, PT3/8 port, and ISO mounting hardware. It features an extruded aluminum profile barrel without external tie rods.
