This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ATE50X15SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ATE50X15SB in place of this model. 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 ATP Single Acting Port Compact Cylinder ATP50X15SB
The AirTAC Airtac ATP Single Acting Port Compact Cylinder ATP50X15SB is a single acting, pull (spring return) DIN-standard tight/compact air cylinder with a Ø50mm bore and 15mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ATE50X15SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ATP Single Acting Port Compact Cylinder ATP50X15SB
This is a single acting pull cylinder with spring extend: the built-in spring holds the rod out and compressed air retracts it, so the part is normally extended at rest and fails to the extended position when air is lost. The 50 mm bore delivers 775 N of pull at 0.5 MPa and 1127.5 N at 0.7 MPa, both figures already net of the return spring, and it needs at least 0.2 MPa (28-145 psi working band) just to overcome the spring. Note that the ATP family is discontinued; the current-production drop-in is the ATE50X15, so confirm the ISO 21287 mounting dimensions before you swap.
The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, which is why it suits tight jigs and guarded stations. The S code in ATP50X15SB means the optional -S magnet is fitted, so CMSE or DMSE reed and solid-state switches can be mounted for end-of-stroke signals, and the B code gives a male rod thread instead of a female one. For sizing, treat about 465 N (roughly 47 kg of pull) as the realistic working force at 0.5 MPa rather than the full 775 N rating.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ATE50X15SB (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 (Ø50mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 775.0 N |
| 0.7 MPa | 1127.5 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

Where the Airtac ATP Single Acting Port Compact Cylinder ATP50X15SB Is Used
Spring-out clamp on a CNC fixture
The spring keeps the clamp engaged on a machined aluminium bracket even if plant air drops, while 775 N of air pull at 0.5 MPa retracts it for loading - the 15 mm stroke suits swing-clearance clamps.
Fail-extended gate on a bottling line
A guide gate that must stay closed when air is lost fits this normally-extended behaviour; the fitted -S magnet drives a DMSE switch to confirm the gate has retracted before the next bottle passes.
Retract stroke on a carton ejector
Air pull withdraws a pusher paddle from the carton path at up to 500 mm/s, and the fixed TPU bumpers at both ends absorb the end-of-travel shock inside the short body.
Replacing the Airtac ATP Single Acting Port Compact Cylinder ATP50X15SB with the ATE50X15SB
Size down to the 40 mm bore (500.3 N pull at 0.5 MPa) if your clamp or retract load is lighter, or step up to the 63 mm bore (1320 N) when you need more margin on the same 1/8" port size. Because the spring returns the rod to its extended home on air loss, this cylinder will not hold a mid-stroke position - use a double acting ACP (now ACE) if you need controlled stops. Mounting brackets from the FA/FB flange, LB foot and CA/CB clevis family bolt to the standard face, and the male rod thread (B code) takes I/Y knuckles directly. Order the ATE50X15 as your current-production replacement and verify the ISO 21287 footprint first.
Replacement checklist
- ✓ Current-production ACE → ATE50X15SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ATP Single Acting Port Compact Cylinder ATP50X15SB FAQ
At 0.5 MPa the net pull is 775 N, rising to 1127.5 N at 0.7 MPa; both figures are already net of the return spring, and at least 0.2 MPa is needed to beat the spring at all. A practical plan is to load it to about 465 N (around 47 kg equivalent) at 0.5 MPa, leaving margin for friction and seal drag. Vertically, the full 775 N corresponds to about 79 kg, so halving for a 2:1 margin lets it lift roughly 39 kg. Operating range is 0.2-1.0 MPa (28-145 psi), proof is 1.5 MPa (215 psi), speed is 50-500 mm/s, and the port is 1/8".
Order the ATE50X15, the current-production ISO 21287 successor: swap the P for an E and you get the same 50 mm bore, 15 mm stroke and force class in a matching short body. Confirm the ISO 21287 mounting dimensions before swapping, since the ATP was built to a DIN-standard footprint. On this model the -S magnet is fitted, so CMSE and DMSE switches mount directly; on an ATE without the S code there is no magnet, so keep the S in the ordering code if you need position sensing.
