Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100S
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100S 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 SGCJ125X160-100S
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore tie-rod actuator features a built-in magnet for position sensing. The genuine ISO 15552 mounting interface makes it dimensionally interchangeable within standard large-bore pneumatic fixtures. Four steel tie rods clamp the aluminum barrel to the covers for high structural rigidity, while the two-way piston seal ensures reliable bidirectional operation. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 safety margin.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, dropping the usable forward travel from the 160 mm maximum down to 60 mm without changing the cylinder body. The retract end remains fixed, allowing precise end-position tuning. Air connects via a G1/2 port, and adjustable air cushions of 40 mm decelerate the piston at both ends. The standard TPU seals operate from -20 to +70 C, with a Viton H option available for environments up to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100S Is Used
Press Stroke Tuning
Dial in the exact 60 to 160 mm clamping reach on a light-duty assembly press using the external adjuster without disassembling the tooling.
Divertor Arm Positioning
Set the precise extend length for a sorting divertor arm to accommodate different package widths on the fly.
Pallet Stop Gate
Adjust the stop gate extension distance on-site to handle varying pallet overhangs while relying on the 6136 N thrust to halt loads safely.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-100S the Right Cylinder?
When sizing this unit, the neighboring 160 mm bore steps the thrust up significantly to 10053 N at 0.5 MPa, while dropping below 125 mm moves you out of this large-bore ISO 15552 family. The 100 mm adjustable window is highly useful for sharing a single spare cylinder across multiple stroke variants or fine-tuning the end position on-site after mechanical mounting. SGCJ mounting options include FA, LB, TC, FTC, TCM1, and TCM2 brackets. The -S suffix indicates the piston magnet is present and ready for CMSG, DMSG, or EMSG sensors. For any application approaching the 500 mm stroke range or beyond, always guide the load externally 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 SGCJ125X160-100S 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. The air port size is G1/2.
The nominal 160 mm stroke is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 60 to 160 mm. The retract end is fixed, and this mechanism only sets the end position rather than holding the load.
