Helpful for Model Matching:
- Full ACT model code or cylinder label
- Published bore: 125, 140, 160, 200, or 250 mm
- Required stroke from the published 25–500 mm table
- Port, rod-end style, mounting-hole pattern, and installed clearance
- Use the ACT drawing for the matching bore; ACQ big-bore dimensions are separate
- Ø250: B male rod end only; female rod-end drawing: Ø125–200
- Compare ports, mounting-hole pattern, rod thread and installed clearance where fit matters
- Mounting torque and procedure: official printed page 139; provide fixture details for help

Avoid a wrong match
- Do not select by body height alone: ACT starts at 125 mm bore
- ACT-S in a label identifies the magnetic option, not a separate indexed product family
- Port size and mounting dimensions change across the published bore sizes
- Ø250 is listed only with B male rod thread; the female rod-end drawing covers Ø125–200.
- Port size: Ø125/140 1/4; Ø160 3/8; Ø200/250 1/2. Blank thread: PT; G option. NPT is not listed.

About ACT
ACT is a double-acting large-bore compact cylinder with bore-dependent ports and rod ends. It is a separate series from ACQ big-bore configurations; compare the matching ACT drawing where installed fit matters. A known model can be quoted directly; an incomplete label is enough to start identification.
Matching Questions
Can I request an ACT quote with an incomplete model?
Yes. Send the known code or a label/photo and add quantity and destination if available. For replacement fit, include mounting and installed dimensions; Ø250 uses B male rod thread in the published guide.
Is ACT-S a separate cylinder family?
No. In the published ACT ordering code, S marks the magnetic option. It is matched as a code option on the ACT family page, not as a separate product page.
