Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-75
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-75 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 150mm 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 SGCJ125X150-75
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 structural rigidity. The G1/2 port feeds the 125 mm bore, generating a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, meaning the usable extend range is 75 to 150 mm while the retract end stays fixed. You can fine-tune the end position without physically changing the cylinder. A two-way piston seal boosts wear resistance, and a Viton H option extends operating temperature to 0-150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-75 Is Used
Press Stroke Tuning
Dial in the exact 75 to 150 mm extend position on a light-duty assembly press without swapping out the entire cylinder body.
Divertor Gate Adjustment
Fine-tune the extend reach of a sorting gate on-site to accommodate different package sizes on the fly.
Shared Spare Inventory
Keep one cylinder as a universal spare for multiple 125 mm bore machines, adjusting the extend window to match the broken unit.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X150-75 the Right Cylinder?
When sizing this unit against its neighbours, stepping down is not an option as 125 mm is the smallest SGCJ bore. Stepping up to the 160 mm bore raises the 0.5 MPa push force to 10053 N if your application outgrows the 6136 N capacity here. The on-site adjustability is ideal for sharing a single spare across multiple stroke variants or dialling in exact end positions during commissioning. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2 brackets. Because this specific SKU lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic sensors. For any stroke over 500 mm, always use a guide rail 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 SGCJ125X150-75 FAQ
This 125 mm bore cylinder features a G1/2 port and a 32 mm rod. It delivers 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical maximum force of 1251 kgf at 1.0 MPa.
The nominal 150 mm stroke is the maximum extend length. The external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable extend range of 75 to 150 mm. The retract end remains fixed, and this stop is for positioning only, not for holding a load.
