Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-20
The AirTAC Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-20 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 SGCJ125X160-20
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 structural rigidity. The G1/2 port feeds a 32 mm piston rod, and a two-way piston seal ensures reliable pressure containment. Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures.
The -20 code defines an external adjuster that shortens the extend stroke on site by up to 20 mm, letting you fine-tune the end position from 140 to 160 mm without swapping the cylinder. It handles a safe working load of about 3682 N, which translates to lifting roughly 313 kg vertically with a 2:1 margin. 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 SGCJ125X160-20 Is Used
Press Tolerance Tuning
Dial in the exact 140 to 160 mm extend position on-site to accommodate material thickness variations without changing the cylinder.
Transfer Stopper Gate
Adjust the stop gate height by up to 20 mm to handle different product profiles on the fly while delivering 6136 N of holding force.
Pallet Positioning Pin
Fine-tune the pin extension length to seat pallets precisely, using the external adjuster to compensate for fixture wear.
Is the Airtac SGCJ125~160 Adjustable Cylinder SGCJ125X160-20 the Right Cylinder?
Size this 125 mm bore against its neighbours: a 160 mm bore yields 10053 N push at 0.5 MPa, while dropping down reduces the footprint. The adjustable stroke is ideal when you need on-site end-position tuning or want a shared spare across multiple stroke variants. Mounting options include FA, LB, TC, FTC, TCM1 and TCM2. Because this 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 to the rod.
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 SGCJ125X160-20 FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum is 1251 kgf at 1.0 MPa. It uses a G1/2 air port and an M27x2.0 rod thread.
The nominal 160 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on site, giving a usable range of 140 to 160 mm. The retract end remains fixed. This mechanism only sets the end position; it does not lock the load.
