The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE40X15SB is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø40mm bore and 15mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.
This AirTAC ATE40X15SB is a single acting pull cylinder, with a spring that extends the rod and air that retracts it. At 0.5 MPa it delivers 500.3 N of pull force, net of the return spring, and 729 N at 0.7 MPa, so it suits light clamping or indexing tasks that need a compact footprint.
The ISO 21287 short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, making it ideal for tight jigs and gantries. The optional -S magnet is fitted here, enabling CMSE or DMSE switches for position sensing, and the male rod thread (B code) simplifies direct coupling. For a safe working load, plan for about 300 N of real work at 0.5 MPa, which equals lifting roughly 30 kg vertically with a 2:1 margin.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 500.3 N |
| 0.7 MPa | 729.0 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa. Single-acting strokes are short (Ø12 to 10 mm, Ø16-100 to 25 mm).

| 40 | Bore size in mm. |
| ×15 | Stroke length in mm. |
| S | Optional built-in magnet for CMSE / DMSE sensors (omit for no magnet). |
| B | Rod type: B = male thread; blank = female thread. |
ACE-family variants: ACE (double acting), ASE / ATE (single acting push / pull), ACED (double rod), ACEJ (adjustable stroke), TACE / TACED (non-rotating twin-guide yoke). Mounting accessories: FA / FB flange, LB foot, CA / CB clevis, CR, SDB pivot, FTC; plus I and Y knuckles. Thread PT (blank) / G.
Use in a CNC fixture to pull a clamp arm down onto a workpiece with 500.3 N at 0.5 MPa, then spring-extend to release. The compact body fits under a machine guard.
Mount on a conveyor frame to retract a stop pin that holds back a product, then spring-extend to let it pass. The 15 mm stroke is enough for small cartons.
Pull a lever on a small pneumatic valve to switch flow direction, with the spring returning the lever to its default position. The male rod thread connects directly to a clevis.
For a smaller option, the ATE32X25 offers 296 N pull at 0.5 MPa, while the ATE50X25 provides 775 N at the same pressure, so you can scale force up or down within the same compact family. This 40 mm bore with a 15 mm stroke is a non-standard stroke, made to order, and suits applications needing a short pull stroke with a spring-extend home position.
Remember, on air loss the spring returns the rod to its extended position; it does not hold a mid-stroke load. Mounting options include FA/FB flange, LB foot, CA/CB clevis, CR, SDB pivot, and FTC brackets, all compatible with the ISO 21287 face.
Quick checklist
At 0.5 MPa, the pull force is 500.3 N net of the spring; at 0.7 MPa, it is 729 N. The minimum working pressure is 0.2 MPa, and the proof pressure is 1.5 MPa (215 psi). Operating pressure range is 0.2-1.0 MPa (28-145 psi).
The short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, so it fits in tight spaces. It uses a fixed TPU bumper at both ends to absorb end-of-stroke energy, and the optional -S magnet allows CMSE or DMSE sensors for position feedback.
