Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50 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 SGCJ125X1000-50
Delivering 6136 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder features an external adjuster that shortens the extend stroke on-site by up to 50 mm. The nominal 1000 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. It handles a safe working load of roughly 3682 N, which translates to lifting about 313 kg vertically with a 2:1 margin.
Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, and the G1/2 port matches the 125 mm bore standard. The default TPU seals provide long service life, while a Viton H option extends the operating temperature range up to 150 C. This non-magnet SKU cannot host CMSG or DMSG sensors, and the adjustable air cushions only decelerate the piston near the stroke ends rather than holding a load.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50 Is Used
Press Tonnage Adjustment
Fine-tune the extend stroke within the 50 mm window to accommodate varying material thicknesses in a large pneumatic press without changing the actuator.
Divertor Gate Positioning
Dial in the exact gate extension end-point on-site to handle different pallet widths on a heavy-duty sorting conveyor line.
Heavy Pallet Lift
Lift loads up to 313 kg vertically with a 2:1 safety margin, using the 1000 mm stroke to elevate goods between floor levels.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1000-50 the Right Cylinder?
Size this 125 mm bore against its neighbors by checking force requirements: the smaller 100 mm bore yields less thrust, whereas stepping up to a 160 mm bore provides 10053 N at 0.5 MPa. The 50 mm adjustable window is ideal when you need to synchronize end positions across multiple fixtures or share a spare cylinder across slightly different stroke variants. Mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. Because this is a non-S model, it lacks a magnet and cannot accept position sensors. At a 1000 mm stroke, large-bore cylinders are highly susceptible to rod bending and side loads, so an external guide bearing is essential to prevent premature seal wear.
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 SGCJ125X1000-50 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. It uses a G1/2 air port and features a 40 mm adjustable air cushion at each end.
An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 950 to 1000 mm. The nominal 1000 mm stroke is the maximum travel, and the retract end remains fixed. This mechanism sets the end position but does not lock the load.
