About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1650
The AirTAC SC125X1650 is a double-acting, single-rod pneumatic cylinder engineered for applications requiring a substantial push force of 6136 N at 0.5 MPa and an extended 1650 mm stroke. As an ISO 6430 class tie-rod cylinder, it features a robust 32 mm piston rod with an M27x2 thread and a 28 mm adjustable air cushion at each end to decelerate large inertial loads smoothly.
This model is a non-standard stroke length, exceeding the standard maximum of 1500 mm for the 125 mm bore, making it a made-to-order solution for specialized long-reach linear motion. With a body length A of 203 mm, the total extended length reaches approximately 1853 mm, demanding careful attention to alignment and external guidance to prevent rod buckling under side loads.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1650 Is Used
Long-Stroke Material Pusher
Provides the 1650 mm reach needed to push heavy billets or panels completely through a cutting or forming station, delivering 11045 N of force at 0.9 MPa.
Pallet Layer Transfer
Moves entire layers of bagged product from a palletizer stripper plate onto a waiting pallet, using its high force capacity to handle consolidated loads smoothly.
Heavy-Duty Gate Actuator
Operates a large sliding gate or diverter chute in mining or aggregate handling, where the long stroke and 6136 N push force at 0.5 MPa are required to shift heavy fabricated structures.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1650 the Right Cylinder?
Choose the SC125 bore when your application demands a push force between the SC100 (3927 N at 0.5 MPa) and the SC160 (10053 N at 0.5 MPa). For this 1650 mm stroke, side-load management is critical; an unsupported rod of this length is highly susceptible to bending and bearing wear. Always integrate an external linear guide or rod support to absorb transverse forces.
To ensure a direct dimensional replacement, match five key specifications: the 125 mm bore, the 1650 mm stroke, the PT1/2 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This cylinder uses the standard TPU seal with an operating temperature range of -20 to +70 C.
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 SC125X1650 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 6136 N and the pull force is 5734 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.
No. For any stroke exceeding 300 mm, and especially for a non-standard 1650 mm stroke, the 32 mm rod is vulnerable to bending and uneven bearing wear under side loads. An external linear guide or a guided cylinder configuration is mandatory to ensure reliable operation and prevent premature failure.
