This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACED63X55SB, 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 ACPD Double Rod Compact Cylinder ACPD63X55SB
The AirTAC ACPD Double Rod Compact Cylinder ACPD63X55SB is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø63mm bore and 55mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED63X55SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD63X55SB
This double acting compact cylinder carries a rod through BOTH covers, so the 63 mm bore delivers 1458.1 N at 0.5 MPa in each direction - the rod-side area governs both strokes, and the through-rod resists rotation and side load while the rear rod can carry a sensor flag. The S code fits the optional -S magnet, so CMSE / DMSE reed or solid-state switches mount directly on the body, and the B code gives a male rod thread. Running range is 0.15-1.0 MPa (22-145 psi) at 30-500 mm/s with a fixed TPU bumper at each end.
The hard-anodized aluminium body follows the ISO 21287 short format, cutting roughly 50% of the mounting length of an ISO 15552 profile cylinder - useful inside clamping fixtures and gantries. Note: this model is discontinued; the current direct is ACED63X55, so confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED63X55SB (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 | Force (both ways) |
|---|---|
| 0.5 MPa | 1458 N |
| 0.7 MPa | 2041 N |
| Max (@1.0 MPa) | 297 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACPD Double Rod Compact Cylinder ACPD63X55SB Is Used
Symmetric clamp fixture
The through-rod lets a machining fixture clamp from either cover with the same 1458.1 N at 0.5 MPa, ideal for a CNC pallet clamp needing balanced grip on both sides of the part.
Conveyor pusher with position sensing
With the -S magnet fitted, CMSE / DMSE switches flag rod position on a bottling-line pusher, while the 55 mm stroke diverts cartons at up to 500 mm/s.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD63X55SB with the ACED63X55SB
For 55 mm of travel with equal force both ways, this 63 mm double-rod unit gives 1458.1 N at 0.5 MPa and 2041.3 N at 0.7 MPa. Step down to the 50 mm bore (881.2 N) for lighter clamps, or up to 80 mm (2356.2 N) for heavier presses. A plain double-rod cylinder will not hold position if air is lost - add a rod lock or pilot check for a held load. FA/FB flange and LB foot brackets bolt to the standard face, and the male rod thread (B) suits I/Y knuckles. Replacement: ACED63X55, same bore, stroke and force class - verify the ISO 21287 mounting dimensions first.
Replacement checklist
- ✓ Current-production ACE → ACED63X55SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD63X55SB FAQ
Because a rod exits both covers, force is equal in both directions: 1458.1 N at 0.5 MPa and 2041.3 N at 0.7 MPa, both using the rod-side area. Maximum output at 1.0 MPa is 297.4 kgf. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed spans 30-500 mm/s.
The hard-anodized aluminium body is an ISO 21287 short format, about 50% shorter in mounting length than an ISO 15552 profile cylinder, with a fixed TPU bumper at each end. The S code carries the optional -S magnet so CMSE / DMSE switches can be mounted. This model is discontinued; order ACED63X55 as the current direct and confirm ISO 21287 mounting dimensions.
