The AirTAC Airtac ACQ Compact Cylinders ACQ32X50BT is a genuine double-acting COMPACT (thin) air cylinder built to JIS dimensions, with a Ø32mm bore and 50mm stroke, PT1/8 air ports and a C-clip / riveted short body that saves mounting depth. Magnetic-switch slots around the body accept position sensors.
The ACQ32X50BT is a double-acting JIS compact cylinder in the 32 mm bore class, delivered with NPT 1/8 in ports - the tapered North-American pipe thread that seals on the thread itself, so tape or sealant replaces the bonded washer a G port would need. At 0.5 MPa it develops 402.1 N on the extend stroke and 301.6 N retracting; running 0.7 MPa raises push to 562.9 N. The B option codes a male piston rod, threaded M14x1.5, ready to couple directly to a knuckle or rod-clevis. Body length is held to a minimum by the C-clip assembly and riveted piston-to-rod joint, so the cylinder drops into shallow machine pockets where a round-body actuator simply has no room. Note the elastomer bumper at each stroke end is a fixed element - it is not a field-adjustable cushion - so any high-energy stop should be taken up by an external shock absorber or a slowed approach valve.

Thread: PT standard (G / NPT available). Related ACQ-family variants: ASQ (single-acting push), ATQ (single-acting pull), ACQD (double rod), ACQJ (adjustable stroke), TACQ (guided / non-rotating).
A dedicated fixture on a machining centre uses the 402.1 N extend force to seat aluminium housings against a hardened stop before milling; the 50 mm stroke clears part loading, and the NPT 1/8 ports tie straight into an imperial-plumbed manifold.
On a secondary-packaging line, the cylinder folds top flaps before taping. The M14x1.5 male rod thread picks up a knuckle lever directly, and the shallow C-clip body slides under a low guardrail that a longer round-body cylinder would foul.
Camera-inspected parts are nudged off a belt at up to 500 mm/s. Because the fixed elastomer bumper cannot be tuned, a flow-control meter-out circuit meters the approach, and a guided variant (TACQ) is the upgrade path if the rod sees side load.
Comparing candidates: the 25 mm bore below delivers 245.4 N push at 0.5 MPa, while stepping up to a 40 mm bore buys 628.3 N. Choose the ACQ32X50BT when your load sits between those figures and the 50 mm stroke covers the travel. A plain cylinder of this family will not hold its position if air pressure is lost - the piston drifts - so add a rod lock or pilot-operated check valve where load retention matters. Because this SKU carries the T code, ports are NPT 1/8 rather than the standard PT; confirm it matches your existing fittings or manifold before ordering. Essentials: 32 mm bore, 50 mm stroke, NPT 1/8 supply port, M14x1.5 male rod thread, magnet only if you add the S code (the body grooves accept an AirTAC reed or electronic switch once the magnet is fitted). Speed range is 30-500 mm/s.
Quick checklist
At 0.5 MPa the 32 mm bore produces 402.1 N push (extend) and 301.6 N pull (retract); at 0.7 MPa push rises to 562.9 N. The ceiling at the full 1.0 MPa rating is about 82 kgf of push. Operation spans 0.15-1.0 MPa, ports are NPT 1/8 on this T-coded version, and the male rod end is threaded M14x1.5.
The trailing T in ACQ32X50BT orders the NPT port variant: a 1/8 in tapered North-American pipe thread that seals progressively along the thread flanks, typically with sealant tape. The default ACQ is supplied with PT (Rc); G/BSPP parallel ports are also available as a made-to-order thread, so match whichever standard your plant plumbing uses.
