About the Airtac SE40 Standard Cylinder SE40BX75SN
The AirTAC SE40BX75SN is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It features a SUS304 stainless steel rod and an NBR seal, making it highly suitable for corrosive or washdown applications. Delivering 628 N of push force at 0.5 MPa, it provides reliable linear motion within a standardized VDMA 24562 footprint.
The extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush on automated machinery. Integrated sensor grooves on three sides allow flexible placement of CMSE reed or DMSE electronic switches. Furthermore, the field-adjustable air cushioning at both ends can be precisely tuned to decelerate the piston smoothly at high speeds, preventing hard end-stop impacts.

Where the Airtac SE40 Standard Cylinder SE40BX75SN Is Used
Flow Wrapper End-Sealing
Drives the sealing jaw mechanism on continuous flow wrappers, using the 628 N push force and NBR seal to withstand washdown cycles in food packaging facilities.
PCB Depaneling Press
Applies controlled straight-line pressure to separate printed circuit boards, utilizing the 75 mm stroke and adjustable cushioning to prevent sudden impact damage to delicate components.
Bottling Line Diverters
Actuates routing gates on beverage filling lines, where the SUS304 rod resists moisture and the DMSE electronic sensors provide precise position feedback.
Is the Airtac SE40 Standard Cylinder SE40BX75SN the Right Cylinder?
When sizing this actuator, consider stepping up to the 50 mm bore if your load requires greater thrust, as the larger bore provides 982 N of push at 0.5 MPa. Conversely, if your application is lighter, the 32 mm bore offers 402 N of push at 0.5 MPa, providing a more compact footprint. Because this is a 75 mm stroke variant, side-load bending on the rod bearing is minimal compared to longer strokes, but an external guide is still recommended for heavy lateral loads. Remember that a standard double-acting cylinder does not hold position when air is exhausted; if your process requires fail-safe load holding, explore the BSE rod lock series. For retrofitting, this model is dimensionally interchangeable per ISO 15552 standards, featuring a PT1/4 port, an M12x1.25 rod thread, and a built-in magnet for position sensing.
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 SE40 Standard Cylinder SE40BX75SN FAQ
This cylinder has a 40 mm bore and delivers 628 N push and 528 N pull at 0.5 MPa. At 0.7 MPa, the push force is 879 N, with a maximum push of 128 kgf at 1.0 MPa. It uses a PT1/4 port and features a 16 mm SUS304 rod with an M12x1.25 thread.
