Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1000mm stroke, G1/2 air ports and adjustable end cushioning. Its large-bore tie-rod build delivers high thrust and drops into standardized ISO 15552 mounting on heavy automation.

About the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that fine-tunes the extend end position on-site. The -30 mm window lets you shorten the usable extend stroke from the 1000 mm maximum down to 970 mm without swapping the unit. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the two-way piston seal ensures reliable bidirectional operation. With a safe working load around 3682 N, it can lift roughly 313 kg vertically with a 2:1 margin.
Because the -S suffix denotes a built-in piston magnet, this version supports CMSG, DMSG, and EMSG reed or electronic switches for precise position sensing. The G1/2 air port feeds the 32 mm rod, which features an M27x2.0 thread and 40 mm adjustable air cushions at both ends to absorb impact. The standard TPU seals handle temperatures from -20 to +70 C, while a Viton H option extends this range up to 150 C for high-heat environments.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30S Is Used
Long-Reach Diversion
Pushes heavy pallets across a transfer line with a 1000 mm stroke, using the 30 mm adjuster to dial in the exact contact point without moving the sensor tracks.
Vertical Lift Gate
Raises a 300 kg mezzanine safety gate, relying on the 6136 N extend force and the EMSG electronic switches to confirm the fully open position.
Press Ejection
Ejects finished parts from a large press bed, using the adjustable end-stop to shorten the stroke by 20 mm and avoid striking a new die fixture.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30S the Right Cylinder?
When sizing this bore, stepping down is not an option below 125 mm in the SGCJ range, but moving up to the 160 mm bore increases the 0.5 MPa push force to 10053 N. The adjustable stroke is particularly useful when you need to share a single spare cylinder across multiple stroke variants or fine-tune the end position after mechanical installation. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because the stroke is 1000 mm, external rod-end support is required to prevent side-load bending and guide the heavy load. Note that a plain cylinder does not hold load on air loss; use an external rod lock or pilot-operated check valve for secure holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Long-stroke side load — support the rod end
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load; support long strokes at the rod end.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-30S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull force. At 0.7 MPa the push is 8590 N and pull is 8028 N. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The nominal 1000 mm stroke is the maximum length. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 970 to 1000 mm. The retract end remains fixed, and the stop only sets the end position rather than locking the load.
