About the Airtac SE63 Standard Cylinder SE63BX300
The AirTAC SE63BX300 is a double-acting ISO 15552 profile cylinder engineered for a 63 mm bore and a 300 mm stroke. It delivers a robust 1559 N push force at 0.5 MPa, utilizing a SUS304 stainless steel piston rod (code B) specifically chosen for corrosive or washdown environments. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while preventing debris accumulation.
This model features field-adjustable pneumatic cushioning at both ends, allowing technicians to tune end-of-stroke deceleration via a set screw to soften hard impacts at operating speeds up to 800 mm/s. Because this specific SKU lacks the -S magnet suffix, it does not support direct position sensing; applications requiring electronic or reed switch feedback should specify an -S variant to utilize CMSE or DMSE sensors.

Where the Airtac SE63 Standard Cylinder SE63BX300 Is Used
Bottling Line Diverter
Actuates routing gates on a beverage bottling line, where the 1559 N push force easily redirects heavy crate traffic and the SUS304 rod withstands daily washdowns.
Pallet Wrapper Film Clamp
Extends 300 mm to position stretch film carriages on automated pallet wrappers, relying on adjustable cushioning to decelerate the payload smoothly at high cycle speeds.
Lab Sample Ejection
Ejects processed chemical samples from testing stations, leveraging the corrosion-resistant stainless steel rod to maintain hygiene and prevent contamination in wet lab conditions.
Is the Airtac SE63 Standard Cylinder SE63BX300 the Right Cylinder?
Selecting this 63 mm bore yields 1559 N of push force at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore provides 982 N of push, while moving up to the 80 mm bore offers 2513 N for heavier payloads. As a standard ISO 15552 cylinder, it serves as a direct dimensional replacement for competing profile cylinders, utilizing the same PT3/8 port and standard mounting accessories. The SUS304 rod is ideal for washdown duty, but note that a plain SE cylinder does not hold its position or lock a load when air pressure is lost or exhausted.
With a 300 mm stroke, the unsupported rod length increases during extension. To prevent rod-bearing bending and premature seal wear under side load, implement an external linear guide to carry the payload mass rather than letting the cylinder rod absorb those lateral forces.
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 SE63BX300 FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N, with a maximum push capacity of 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, it is dimensionally interchangeable with any standard ISO 15552 profile cylinder, matching standard mounting and PT3/8 port sizes. However, it cannot hold a load if air pressure is lost; the adjustable cushion only decelerates the piston near the end of the stroke and does not function as a braking or locking mechanism.
