About the Airtac SE50 Standard Cylinder SE50BX320S
The AirTAC SE50BX320S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and 320 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, utilizing a PT1/4 port and a Ø20 mm rod with an M16x1.5 thread. This specific configuration features a SUS304 stainless steel rod (code B) paired with a built-in magnet (code S), making it highly suitable for corrosive or washdown environments where position feedback is required.
The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies sensor placement across its three integrated grooves. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration, softening hard impacts during high-speed cycling up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50BX320S Is Used
Food Packaging Diverter
Leveraging the SUS304 rod for washdown duty, this 50 mm bore cylinder actuates flow diverter gates on food packaging lines, providing 982 N of push force to reliably redirect heavy product cartons at high speed.
Bottling Line Starwheel
Drives the indexing starwheel on an automated beverage bottling conveyor, using its 320 mm stroke and integrated magnet to trigger DMSE electronic sensors for precise container spacing.
Lab Sample Handler
Moves sample racks within a chemical diagnostic laboratory, where the stainless steel rod resists harsh reagents and the adjustable cushioning ensures delicate vials are not jostled at stroke ends.
Is the Airtac SE50 Standard Cylinder SE50BX320S the Right Cylinder?
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore cylinder sits neatly between the 40 mm option (628 N push) and the 63 mm option (1559 N push), allowing you to step up or down based on your exact dynamic load requirements. Because the stroke is 320 mm, the unsupported piston rod is subjected to greater bending moments under side loads; integrating an external guide rail is strongly recommended to prevent premature rod-bearing wear.
As a standard ISO 15552 profile cylinder, it provides a dimensionally interchangeable footprint, serving as a direct replacement for other ISO 15552 cylinders while utilizing shared mounting hardware. Remember that the adjustable air cushion only decelerates the piston near the stroke end; it does not hold the load. If air pressure is lost or the valve is centered, the cylinder will drift. For static holding requirements, consider a BSE rod lock variant or an external pilot-operated check valve.
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 SE50 Standard Cylinder SE50BX320S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
No. The field-adjustable air cushioning at both ends only decelerates the piston near the stroke end and does not act as a braking or locking mechanism. If air is lost or the valve is centered, the rod will drift. For position holding, you need a BSE series rod lock cylinder or an external pilot-operated check valve.
