About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X2000S
The AirTAC SC125X2000S is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the maximum operating pressure of 0.9 MPa). With a 32 mm diameter piston rod and an M27x2 knuckle thread, this cylinder is built for heavy linear applications requiring a very long 2000 mm stroke.
This model features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The 2000 mm stroke is a non-standard, made-to-order length that exceeds the standard 1500 mm maximum for the 125 mm bore. The adjustable air cushion (28 mm length) decelerates the piston at stroke ends to reduce impact, while the PT1/2 port threads provide a standard pneumatic connection.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X2000S Is Used
Long-Stroke Material Pusher
The 2000 mm stroke and 6136 N force at 0.5 MPa are ideal for cross-belt pushers or long-reach material diverters on wide conveyor lines, where a full extension is needed to sweep products into a chute.
Heavy-Duty Clamping Fixture
With 11045 N of clamping force at 0.9 MPa, this cylinder secures large weldments or heavy castings in jigs. The built-in magnet enables sensor confirmation of the clamped position before a cycle starts.
Vertical Pallet Lift Assist
Use in a vertical lift-assist mechanism for heavy pallets. The large 125 mm bore provides the necessary push force to raise a load, while the adjustable cushioning prevents hard stops at the top and bottom of the 2000 mm travel.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X2000S the Right Cylinder?
Choose the SC125 bore when your application needs a push force between 6136 N and 11045 N. For a step down in force, the SC100 bore offers 3927 N at 0.5 MPa. When specifying a 2000 mm stroke, side-load management is critical—an unsupported 32 mm rod at this extension is highly susceptible to bending under radial loads. Always use an external linear guide or a guided cylinder configuration to protect the rod bearings and ensure long seal life.
For a direct replacement, match five key points: 125 mm bore, 2000 mm stroke, PT1/2 port thread, the built-in magnet for sensor mounting, and the basic (no bracket) mounting configuration. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac AIRTAC SC125-160 Standard Cylinder SC125X2000S FAQ
At the standard operating pressure of 0.5 MPa, the push force is 6136 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf, but the cylinder should only be operated within the 0.15–1.0 MPa range.
A 32 mm rod extending 2000 mm is vulnerable to bending and buckling under side loads. You must guide the load externally with a linear rail system or use a rod-alignment coupler. For high side-load applications, consider a guided cylinder instead of a basic tie-rod cylinder to protect the rod bearing and seals from premature wear.
