Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 160mm 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 SGCJ125X160-30S
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses four steel rods to clamp its aluminium barrel for high rigidity. The G1/2 port and M27x2.0 rod thread equip the 125 mm bore for heavy-duty actuation, while the integrated -S magnet supports CMSG/DMSG/EMSG position switches.
An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 130 to 160 mm without changing the cylinder body. This on-site fine-tuning is ideal for dialing in end positions, and the unit handles a safe working load of roughly 3682 N or about 313 kg lifted vertically with a 2:1 margin. The retract end remains fixed, and the adjustable air cushions only decelerate the piston; they do not hold the load on air loss.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30S Is Used
Press Fit Tuning
Fine-tune the 130 to 160 mm extend stroke on-site to dial in the exact insertion depth for bearing press fits without swapping actuators.
Divertor Gate Stop
Adjust the extend stopper position by up to 30 mm to accommodate different package sizes on a heavy-duty sorting line.
Pallet End Stop
Secure heavy pallets using 6136 N of push force, tweaking the stop screw to align with varying pallet overhangs.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-30S the Right Cylinder?
When sizing this 125 mm bore, the smaller 100 mm class drops thrust significantly, whereas stepping up to the 160 mm bore yields 10053 N push at 0.5 MPa. The 30 mm adjust window is invaluable when sharing a spare cylinder across machines with slightly different extend lengths, as you can tune the end position on-site. SGCJ mounting options include FA, LB, TC, FTC, TCM1, and TCM2. The -S suffix confirms the piston magnet is present for CMSG/DMSG/EMSG sensors. For strokes at or beyond 500 mm, always use a guide rail to prevent side-load damage to the rod seals.
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 SGCJ125X160-30S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum is 1251 kgf at 1.0 MPa. This 125 mm bore cylinder features a G1/2 air port.
The external adjuster allows you to shorten the extend stroke by up to 30 mm on-site, yielding a usable extend range of 130 to 160 mm. The nominal 160 mm stroke is the maximum, and the retract end is fixed. This mechanism sets the end position and is not a load lock.
