The AirTAC Airtac ACEJ50~63 Adjustable Compact Air Cylinder ACEJ63X60-20B is a genuine double acting, adjustable stroke ISO 21287 compact air cylinder with a Ø63mm bore and 60mm 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.
The ACEJ63X60-20B is a double acting ISO 21287 compact cylinder with an adjustable extend stroke. Its 63 mm bore delivers 1558.6 N push and 1458.1 N pull at 0.5 MPa, rising to 2182.1 N at 0.7 MPa, with a theoretical peak of 317.9 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window: an external stop screw trims the 60 mm extend stroke down to 40 mm on site, so one cylinder covers a 40-60 mm range without reordering. The male rod thread (B code) bolts straight to tooling.
The hard-anodized aluminium body with an S45C hard-chrome plated 16 mm rod saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters in tight gantries and guarding. A fixed TPU bumper at each end absorbs end-of-stroke energy. Running on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and 30-500 mm/s, it lifts roughly 95 kg vertically at 0.5 MPa; halving that for a 2:1 margin means planning vertical lifts of about 48 kg.

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 | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

| -20 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| S | Optional built-in magnet for CMSE / DMSE sensors (omit for no magnet). |

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.
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive welding jigs, and the 40-60 mm adjustable window absorbs fixture tolerance without changing the cylinder.
Mounting length about 50% shorter than an ISO 15552 profile cylinder lets this unit slot between conveyor frames to divert cartons at 30-500 mm/s.
With about 95 kg of thrust at 0.5 MPa, the male-threaded 16 mm rod swings heavy safety gates on warehouse palletizing cells; the fixed TPU bumper quiets each end stop.
At 0.5 MPa this bore pushes 1558.6 N, so size real work at roughly 935 N (about 95 kg of thrust) to leave margin. A 50 mm bore offers 981.7 N push and a 80 mm bore 2513.3 N, so step up if your load exceeds the 63 mm margin. Note the stop screw is a mechanical end stop for the extend stroke only: on air loss the piston drifts, so it is not a mid-stroke lock. FA flange, LB foot and I/Y rod knuckles fit the ISO 21287 face. If you need position sensing, order the -S variant, which carries the optional magnet for CMSE / DMSE switches; this model has no magnet fitted.
Quick checklist
At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N; at 0.7 MPa push is 2182.1 N and pull 2041.3 N, with a theoretical maximum of 317.9 kgf at 1.0 MPa. The -20 code sets a 20 mm adjustment window: an external stop screw shortens the 60 mm extend stroke to any setting from 40 to 60 mm. It is double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, with a fixed TPU bumper at both ends and a 1/8" PT port.
It is an ISO 21287 compact cylinder: hard-anodized aluminium body, S45C hard-chrome plated 16 mm rod, threaded aluminium covers and a fixed TPU bumper at each end, with a male rod thread from the B code. The body is about 50% shorter in mounting length than an ISO 15552 profile cylinder. Sensors are possible only on the -S variant, where the optional magnet works with CMSE / DMSE switches; this model has no magnet, so no switch can be mounted.
