Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X350-20
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X350-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø160mm bore and 350mm stroke, G3/4 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 SGCJ160X350-20
Delivering 10053 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder uses four steel rods to clamp its aluminum barrel for high structural rigidity. The G3/4 port feeds a double-acting single-rod mechanism that runs at 30-500 mm/s, while a two-way piston seal maximizes wear resistance.
The -20 code defines an external adjuster that shortens the extend stroke on-site by up to 20 mm, letting you fine-tune the end position from 330 to 350 mm without changing the hardware. It handles a safe working load of about 6032 N, which translates to lifting roughly 512 kg vertically with a 2:1 margin. Standard TPU seals support -20 to +70 C, though a Viton H option extends this to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X350-20 Is Used
Press End-Position Tuning
Dial in the exact 330 to 350 mm extend reach on a metal stamping press without swapping the cylinder, using the external adjuster to compensate for tooling wear.
Pallet Stop Calibration
Fine-tune the stopping height of heavy pallet lifts on-site, ensuring precise placement regardless of fluctuating load weights.
Divertor Reach Adjustment
Adjust the extend stroke window by up to 20 mm to perfectly time the contact point of a heavy package divertor without repositioning the assembly.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ160X350-20 the Right Cylinder?
When sizing this unit, the 125 mm bore provides 6136 N push at 0.5 MPa for lighter jobs, while the 200 mm bore jumps to 15708 N if you need substantially more power. The 20 mm adjustable window is ideal for sharing a single spare cylinder across multiple machines that have slightly different extend endpoints. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors. For this 350 mm stroke, always use an external guide to prevent side-load damage.
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 SGCJ160X350-20 FAQ
This 160 mm bore cylinder features a G3/4 air port and a 40 mm rod. It generates 10053 N push and 9425 N pull at 0.5 MPa, increasing to 14074 N push and 13194 N pull at 0.7 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
The -20 indicates an external adjuster that shortens the extend stroke by up to 20 mm on-site. The usable extend range is 330 to 350 mm, with 350 mm being the maximum nominal stroke. The retract end remains fixed, and this stop mechanism only sets the end position; it does not lock the load.
