About the Airtac SAI50 Standard Cylinder SAI50BX475S
The AirTAC SAI50X475-S is a double-acting ISO 15552 profile cylinder engineered for rigorous automation tasks. Delivering a push force of 982 N and a pull force of 825 N at 0.5 MPa, this 50 mm bore unit utilizes a 475 mm stroke to drive medium-duty clamping and lifting mechanisms. Its extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or washdown environments. Equipped with a factory-installed magnet (-S), the cylinder integrates seamlessly with CMSE and DMSE sensor switches seated in the dual-side grooves of the barrel. Fluid compatibility is limited to 40 um filtered air, operating efficiently between 0.15 and 1.0 MPa.

Where the Airtac SAI50 Standard Cylinder SAI50BX475S Is Used
Package Diverting
Actuates routing gates on packaging lines, using the 475 mm stroke to push cartons cleanly between parallel conveyor belts.
Component Seating
Presses bearings or bushings into housings on an assembly line, leveraging 982 N of push force at 0.5 MPa.
Pallet Lifting
Raises lightweight product tiers or tote bins from floor level to ergonomic working heights within automated storage cells.
Is the Airtac SAI50 Standard Cylinder SAI50BX475S the Right Cylinder?
Selecting this 50 mm bore is optimal when applications require more thrust than a 40 mm bore provides (628 N at 0.5 MPa), but do not warrant the bulk of a 63 mm bore (1559 N at 0.5 MPa). The 475 mm stroke places substantial extension on the rod, making the assembly highly susceptible to side-load bending and rod-bearing wear. To mitigate premature failure, implement an external guide rail or utilize a dedicated guided cylinder to absorb lateral forces.
As a standard double-acting actuator, this model relies on continuous air pressure to move and cannot maintain its position if pneumatic supply is lost or exhausted. The adjustable air cushions at both ends function strictly to decelerate the piston near stroke ends, not to act as a braking mechanism. For operations requiring true load holding upon pressure loss, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI50 Standard Cylinder SAI50BX475S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X475-S is dimensionally interchangeable per ISO 15552. You can drop it into existing foot, flange, or trunnion mounts designed for standard ISO 15552 profile cylinders without modifying the plate geometry.
