About the Airtac SE63 Standard Cylinder SE63BX420H
The AirTAC SE63BX420H is a double-acting, single-rod ISO 15552 profile cylinder engineered for severe thermal and corrosive environments. It delivers a robust 1559 N push force at 0.5 MPa (2182 N at 0.7 MPa) across a 420 mm stroke. Configured with a SUS304 stainless steel rod and high-temperature FKM Viton seals, it operates reliably from -20 to +150 C, making it ideal for washdown or heated machinery. The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies fixture integration.
Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, absorbing kinetic energy smoothly rather than relying on a fixed rubber bumper. Because this specific SKU lacks a built-in magnet, it does not support direct CMSE or DMSE position sensing without modification. The standardized ISO 15552 mounting interface ensures strict dimensional interchangeability with other ISO 15552 profile cylinders, streamlining equipment retrofits.

Where the Airtac SE63 Standard Cylinder SE63BX420H Is Used
Medical Autoclave Doors
Handles the heavy door operation of steam sterilizers, utilizing the 1559 N push force and FKM Viton seals to withstand sustained 150 C ambient heat.
Bottling Plant Diverter
Routes heavy crate assemblies along processing lines where the SUS304 stainless rod provides necessary resistance against daily chemical washdowns.
Thermoforming Press
Actuates mold separation stages in high-temperature plastic forming machinery, relying on the 420 mm stroke and adjustable end cushions to arrest momentum.
Is the Airtac SE63 Standard Cylinder SE63BX420H the Right Cylinder?
Delivering 1559 N of push force at 0.5 MPa, this 63 mm bore fits neatly between the 50 mm model (982 N push) and the 80 mm model (2513 N push), letting you step up or down to match exact load requirements. If your machinery must hold a vertical load during an air loss or valve centering event, note that a standard SE cylinder will drift; an external pilot-operated check valve or the AirTAC BSE rod lock variant is required for true position holding.
At a 420 mm stroke, the unsupported load on the Ø20 mm rod and its bearing increases the risk of bending under side loads. For heavy offset loads, implement an external linear guide to prevent premature seal wear. When replacing an existing ISO 15552 unit, match the 63 mm bore, 420 mm stroke, PT3/8 port, and mounting hardware; the FKM seal and SUS304 rod here are specifically chosen for high-temperature or corrosive fluid exposure.
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 SE63BX420H FAQ
At 0.5 MPa, it 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 when operating at the 1.0 MPa pressure limit.
Yes. The SE63BX420H shares the exact ISO 15552 mounting interface and PT3/8 port locations, ensuring dimensional interchangeability with other standard profile cylinders. You can swap it directly using your existing FA or LB mounting hardware.
