The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE63X5S is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø63mm bore and 5mm 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 ATE63X5S is a single acting pull cylinder with spring return, meaning the spring extends the rod and air retracts it. At 0.5 MPa it delivers 1320 N of pull force, net of the return spring, and 1903.2 N at 0.7 MPa, with a minimum working pressure of 0.2 MPa.
The ISO 21287 compact body is about 50% shorter than a profile cylinder, making it ideal for tight machine guarding. This model includes the optional -S magnet, so you can mount CMSE or DMSE sensors for position detection. For a real-world load estimate, 1320 N translates to roughly 80 kg of lifting capacity with a 2:1 safety 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 | 1320.0 N |
| 0.7 MPa | 1903.2 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).

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 the 1320 N pull to retract a locating pin in a CNC fixture, where the spring extends the pin to locate the part and air pulls it clear for unloading.
Mount on a packaging line to pull a diverter gate open, with the spring closing it automatically when air pressure is removed for safety.
Retract a spring-loaded latch on a machine access door, using the 5 mm stroke for a positive unlock action and the spring to re-engage the lock.
For lighter duty, the ATE50X25 offers 775 N of pull at 0.5 MPa, while this 63 mm bore provides 1320 N for heavier retraction tasks. Since it is single acting, the spring returns the rod to its extended position on air loss, but it will not hold a mid-stroke position. The 1/8" port suits standard shop air, and the female M10x1.5 rod thread accepts common clevis or rod-end attachments.
Quick checklist
The ATE63X5S provides a pull force of 1320 N at 0.5 MPa and 1903.2 N at 0.7 MPa, both net of the return spring. It operates from 0.2 to 1.0 MPa (28-145 psi) with a proof pressure of 1.5 MPa (215 psi).
The hard-anodized aluminum body is about 50% shorter than an ISO 15552 profile cylinder, saving mounting space in tight fixtures. It uses fixed TPU bumpers at both ends to absorb energy, and the included -S magnet allows CMSE or DMSE sensors to be attached for position feedback.
