About the Airtac SAID32 Double Rod Cylinder SAID32X250
The AirTAC SAID32X250 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 250mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 483N of force in each direction at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This configuration uses a standard carbon steel rod and PT tapered port threads. The rear rod protrusion allows you to mount a cam or position flag on the back side to trigger external sensors while the front rod drives the primary workpiece. It supports adjustable air cushioning at both ends to smoothly decelerate the piston near stroke limits.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID32 Double Rod Cylinder SAID32X250 Is Used
Symmetric Force Transfer
Provides exactly 483N of thrust and retraction force at 0.7 MPa, making it ideal for symmetric transfer mechanisms where push and pull dynamics must remain perfectly balanced.
Anti-Rotation Slides
The twin-rod design prevents piston rotation during travel, offering superior guidance for lifting slides and indexing mechanisms that require precise angular stability.
Through-Rod Sensing
The rear protruding rod can be used to mount a cam or limit flag, allowing external position sensors to track stroke status without interfering with the primary front-side workpiece.
Is the Airtac SAID32 Double Rod Cylinder SAID32X250 the Right Cylinder?
Select this 32mm bore double-rod actuator when an application requires equal push and pull forces alongside dual-side guidance. If you need higher thrust, stepping up to the 40mm bore raises the both-way force to 528N at 0.5 MPa. Choose a double-rod SAID over a single-rod SAI when you need to drive a secondary mechanism from the rear or require superior anti-rotation resistance. For this 250mm stroke, the unsupported load length increases the risk of rod-bearing bending, so utilizing an external guide is recommended.
Ensure your design accommodates the longer overall length required for the rear rod to protrude fully. The mounting interface is dimensionally interchangeable per ISO 15552, using a reduced accessory set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the adjustable air cushion only decelerates the piston near stroke end; it does not hold a load. If position holding without live air pressure is required, consider an external rod lock or a SAIL cylinder.

- ✓ 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 SAID32 Double Rod Cylinder SAID32X250 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It delivers 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa for both extension and retraction.
Yes, it is dimensionally interchangeable with ISO 15552 profile cylinders. However, the SAID series uses a reduced mounting set which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not support the FB, CA, CB, or CR mounts found on single-rod variants.
