About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900
The AirTAC SC160X900 is a double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa, scaling up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 40 mm diameter piston rod and a 900 mm stroke, this model is built for heavy-duty linear tasks requiring significant force over a long travel distance.
This cylinder features an adjustable pneumatic cushion (29 mm length) to decelerate the piston smoothly at the end of its stroke, reducing impact and noise. The body length A is 239 mm, making the total extended length approximately 1139 mm. It uses a standard PT3/4 port and operates reliably on filtered air within a -20 to +70 °C temperature range with its default TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900 Is Used
Sawmill Log Handling
Provides the high force and long stroke needed to actuate log kickers, sorters, and stops on heavy timber conveyors, reliably operating in dusty conditions with filtered air.
Agricultural Equipment Actuation
Powers the lift and tilt functions on large bale handlers or fertilizer spreader chutes, delivering 18095 N of force at 0.9 MPa for moving dense, heavy materials.
Scrap Metal Baler Ram
Drives the compression plate in a two-ram baler, using its 10053 N push at 0.5 MPa to compact scrap metal, with the adjustable cushion protecting the cylinder from high-impact shocks.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X900 the Right Cylinder?
Select the SC160X900 for applications demanding around 10,000 N of force at standard plant pressure. If your load requires less force, stepping down to the SC125 bore reduces push force to 6136 N at 0.5 MPa, potentially saving on air consumption and physical space. For a 900 mm stroke, carefully evaluate side-loading conditions; an unsupported 40 mm rod at full extension is vulnerable to bending under lateral forces. Always use an external guide system or linear bearing to absorb side loads and protect the rod bearing and piston seals.
To ensure a direct replacement, match these five key specifications: the 160 mm bore, the 900 mm stroke, the PT3/4 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This cylinder is not an ISO 15552 profile cylinder; it is a tie-rod design and will only directly interchange with another AirTAC SC series cylinder of the same specifications.
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 SC160X900 FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X900 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or the load will drop. The adjustable air cushion is for end-of-stroke deceleration only, not for locking. You must add an external mechanical lock, a rod brake, or a pilot-operated check valve to safely hold a load without live pressure.
