Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50S
The AirTAC Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50S is a genuine double acting, adjustable stroke ISO 15552 (orig. ISO 6431) tie-rod air cylinder with a Ø250mm bore and 900mm stroke, G1 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 SGCJ200-250 Adjustable Cylinder SGCJ250X900-50S
Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder handles heavy-duty positioning with ease. The four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, and the G1 air port feeds the 50 mm piston rod. Because it carries the -S suffix, a built-in piston magnet is ready for CMSG, DMSG or EMSG reed and electronic switches. Note that TPU seals are not offered on this 250 mm bore; standard NBR packing handles the -20 to +70 C range, with a Viton H option for 0-150 C heat.
The -50 code means an external adjuster can shorten the extend stroke on-site by up to 50 mm, letting you fine-tune the end position from 850 to 900 mm without swapping the cylinder. This on-site tuning yields a safe working load of roughly 14726 N, which translates to lifting about 1251 kg vertically with a 2:1 margin. The retract end remains fixed, and the 60 mm adjustable air cushions at both ends decelerate the payload smoothly.

Where the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50S Is Used
Heavy Pallet Lifting
Raises 1251 kg vertical loads with a 2:1 safety margin, using the 50 mm extend adjuster to fine-tune the exact lift height for different pallet stacks.
Press End Tuning
Provides 24543 N of pressing force at 0.5 MPa, with the external stop screw allowing operators to shorten the extend stroke by up to 50 mm for precise material forming.
Automated Storage Retrieval
Moves heavy shuttles across a 900 mm span while the built-in magnet and CMSG sensors track position for precise rack indexing.
Is the Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X900-50S the Right Cylinder?
When sizing this 250 mm bore unit against its neighbors, a 200 mm bore yields 15708 N push at 0.5 MPa, whereas this 250 mm model reaches 24543 N. The adjustable stroke is ideal when you need to share a spare cylinder across stroke variants or dial in an exact end position on the factory floor. SGCJ mountings include Basic, FA, LB, TC, FTC, TCM1 and TCM2. Because the nominal stroke is 900 mm, always use an external guide to prevent rod bending and absorb side loads. Remember that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for held loads.
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 SGCJ200-250 Adjustable Cylinder SGCJ250X900-50S FAQ
It generates 24543 N push and 23562 N pull at 0.5 MPa, rising to 34360 N push and 32986 N pull at 0.7 MPa. The theoretical maximum is 5006 kgf at 1.0 MPa. The air port is G1, the rod is 50 mm with an M42x2.0 thread, and it has 60 mm adjustable air cushions.
The nominal 900 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 850 to 900 mm so you can set the exact end position without changing the cylinder. The retract end is fixed.
