This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACE63X50SB, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACP Compact Cylinder ACP63X50SB
The AirTAC ACP Compact Cylinder ACP63X50SB is a double acting DIN-standard tight/compact air cylinder with a Ø63mm bore and 50mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACE63X50SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACP Compact Cylinder ACP63X50SB
A double acting compact cylinder in the DIN-standard ACP series, the ACP63X50SB pairs a 63 mm bore with a 50 mm stroke and a male threaded rod. At 0.5 MPa it pushes 1558.6 N and pulls 1458.1 N, rising to 2182.1 N at 0.7 MPa. The short ISO 21287-class body cuts mounting length by roughly half compared with an ISO 15552 profile cylinder, so it slots into tight welding fixtures and press gantries where a full-length body cannot. The -S code on this model means the magnet is fitted, so CMSE or DMSE reed and solid-state switches can be clipped on for end-of-stroke signalling.
Construction is a hard-anodized aluminium body with threaded aluminium covers, an S45C hard-chrome rod, a two-way grease-storing piston seal and fixed TPU bumpers at both ends. Note that this model is discontinued; the current-production direct is ACE63X50, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACE63X50SB (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø63mm)
| 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 | |
The ACE63X50SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACP Compact Cylinder ACP63X50SB Is Used
Welding fixture clamping
The 1558.6 N push at 0.5 MPa clamps steel brackets in automotive weld cells, and the short body fits between fixture plates where space is tight.
Small press and crimp station
With about 2182 N available at 0.7 MPa, this bore drives light crimping and staking heads on electronics assembly benches at 30-500 mm/s.
Replacing the Airtac ACP Compact Cylinder ACP63X50SB with the ACE63X50SB
At 63 mm bore you sit in the mid-heavy band of the ACP range: a 50 mm bore gives 981.7 N push at 0.5 MPa, while an 80 mm bore reaches 2513.3 N if you need more force in the same short body. Keep in mind that a plain cylinder drifts when air is lost - add a rod lock or pilot check valve if the load must stay put. Foot (LB), flange (FA/FB) and clevis (CA/CB) mountings plus I/Y rod knuckles suit standard fixtures, and the fitted -S magnet accepts CMSE/DMSE switches. Order ACE63X50 as the current replacement and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ACE63X50SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACP Compact Cylinder ACP63X50SB FAQ
Push is 1558.6 N and pull 1458.1 N at 0.5 MPa; 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. It is double acting, 63 mm bore, 50 mm stroke, 16 mm rod, 1/8" PT ports, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, with fixed TPU bumpers at both ends.
Order ACE63X50, the current-production ISO 21287 successor: swap the P for an E and you get the same bore, stroke and force class in a matching short body. Because the ACP was DIN-standard, confirm the ISO 21287 mounting dimensions before swapping. The male rod thread (B) and the -S magnet for CMSE/DMSE switches carry over as options on the ACE.
