The AirTAC Airtac ATE Single Acting Guided Compact Cylinder ATE32X5 is a genuine single acting, pull (spring return) ISO 21287 compact air cylinder with a Ø32mm 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 ATE32X5 is a single acting pull cylinder with a spring-return mechanism that extends the rod when air is removed. It delivers a net pull force of 296 N at 0.5 MPa, enough for light clamping or indexing tasks in a compact envelope.
The ISO 21287 short body takes up about 50% less mounting length than an ISO 15552 profile cylinder, which helps when space is tight. With a 5 mm stroke, it suits precise, short movements. The fixed TPU bumper at both ends absorbs impact, and the hard-anodized aluminium body resists wear. As a rule of thumb, plan for about 178 N of real work at 0.5 MPa, which translates to lifting roughly 18 kg vertically 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 | 296.0 N |
| 0.7 MPa | 434.2 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).

| 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 the 296 N pull to retract a locating pin in a drill jig, freeing the part for quick changeover between operations.
Drive a label tamp pad with a short 5 mm stroke to press labels onto small cartons on a packaging line, with the spring returning the pad after each cycle.
Retract a locking bolt on a machine guard with a 296 N pull, ensuring the guard stays closed until air pressure is applied.
For a smaller option, the ATE25X5 offers a 170.9 N pull at 0.5 MPa. If you need more force, the ATE40X5 provides 500.3 N at the same pressure. The ATE32X5 has a 1/8" port and a female M8x1.25 rod thread. Remember, the spring returns the rod to its extended position on air loss; it does not hold a mid-stroke position. This model has no magnet, so order the -S code if you need to mount CMSE or DMSE sensors.
Quick checklist
The ATE32X5 provides a net pull force of 296 N at 0.5 MPa and 434.2 N at 0.7 MPa. These figures already account for the return spring. The minimum working pressure is 0.2 MPa, and the maximum is 1.0 MPa (145 psi).
The ISO 21287 body is about 50% shorter than an ISO 15552 profile cylinder, so it fits into tight spaces on gantries or inside machine frames. The fixed TPU bumper at each end absorbs end-of-stroke impact. This model does not have a magnet; you must order the -S option to use CMSE or DMSE sensors.
