Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 100mm 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 SGCJ125X100-100S
Delivering 6136 N of push force at 0.5 MPa, this ISO 15552 tie-rod cylinder handles serious work using a 125 mm bore and a G1/2 port. Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, while the two-way piston seal ensures reliable bidirectional operation. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures without custom brackets.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm from the 100 mm nominal maximum, letting you fine-tune the end position without swapping the cylinder. The retract end remains fixed, and the adjustable air cushion provides 40 mm of deceleration at each end. With a safe working load around 3682 N, it can lift roughly 313 kg vertically with a 2:1 margin. The -S suffix provides a built-in piston magnet for CMSG, DMSG, or EMSG sensors.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100S Is Used
Press Stroke Tuning
Dial in the exact 0-100 mm extend position on a light assembly press without machining new spacers, using the external adjuster to set the precise crush depth.
Variable Transfer Stops
Act as a retractable lane diverter on a conveyor, adjusting the stop extension length on-site to accommodate different package widths on the fly.
Pallet Positioning Gate
Control a pallet flow gate where the full 100 mm stroke might need shortening by 20 mm to clear a new fixture, allowing rapid mechanical position updates.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X100-100S the Right Cylinder?
Size this 125 mm bore against its neighbors: the 160 mm bore jumps to 10053 N push at 0.5 MPa, while smaller bores offer less force. The 125 mm sits at the low edge of the large-bore family, ideal when 6136 N is sufficient. The 100 mm adjustable window is perfect for sharing a single spare cylinder across multiple stroke variants and fine-tuning end positions on-site. SGCJ mountings include FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet supports CMSG/DMSG/EMSG switches. For any stroke over 500 mm, use a guide rail to prevent rod side-loading and 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 SGCJ125X100-100S FAQ
This 125 mm bore cylinder uses a G1/2 port and generates 6136 N push and 5734 N pull at 0.5 MPa. At 0.7 MPa it outputs 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The 100 mm nominal stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke by up to 100 mm on-site, meaning the usable extend range is 0-100 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock; you need an external rod lock or pilot-operated check valve to hold a load on air loss.
