Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1400-20
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1400-20 is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø125mm bore and 1400mm 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 SGCJ125X1400-20
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 rigidity. The G1/2 port and M27x2.0 rod thread equip the 125 mm bore for heavy-duty actuation, while the two-way piston seal ensures reliable pressure containment.
An external adjuster allows you to shorten the extend stroke on-site by up to 20 mm, meaning the usable forward travel spans 1380 to 1400 mm without swapping the cylinder. This on-site fine-tuning is invaluable for dialing in exact end positions. With a safe working load around 3682 N, it handles roughly 313 kg lifted vertically with a 2:1 margin. The standard TPU seals operate from -20 to +70 C, though a Viton H option extends this to 150 C.

Where the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1400-20 Is Used
Long-Reach Press Ejection
Pushes finished parts out of a deep press bed over a 1400 mm span, using the 20 mm adjuster to dial the exact eject position without moving the cylinder mount.
Multi-Level Lowering Ramp
Lowers heavy pallets through a long vertical path, relying on the 40 mm adjustable air cushions to decelerate the load smoothly at the bottom of the stroke.
Extended Transfer Pusher
Transfers large automotive components across a wide conveyor gap, fine-tuning the final resting position on-site via the external stop screw.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X1400-20 the Right Cylinder?
When sizing this unit, stepping down to a smaller bore drops the 0.5 MPa push force significantly, whereas moving up to a 160 mm bore yields 10053 N. The adjustable stroke feature is particularly useful when you need to standardize one spare cylinder across multiple stroke variants or fine-tune a machine's end position on the floor. SGCJ mounting options include FA, LB, TC, FTC, TCM1, and TCM2. Because this is a 1400 mm stroke, external guide rails and rod-end support are mandatory to prevent rod bending under side loads. Note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection.
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 SGCJ125X1400-20 FAQ
This 125 mm bore cylinder features a G1/2 port and delivers 6136 N push and 5734 N pull at 0.5 MPa. At 0.7 MPa, it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The -20 code indicates an external adjuster that lets you shorten the extend stroke by up to 20 mm on-site. The nominal 1400 mm stroke is the maximum, so usable forward travel is 1380 to 1400 mm, while the retract end remains fixed. This mechanism only sets the end position and does not lock the load.
