About the Airtac SAID100 Double Rod Cylinder SAID100BX325S
The AirTAC SAID100X325-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and a 325mm stroke. Because the twin rods occupy both sides of the piston, the effective annulus area is identical in each direction, yielding an equal extend and retract force of 3681 N at 0.5 MPa. The piston exits both end covers simultaneously, allowing you to mount a primary workpiece on the front rod and a position flag or cam on the rear rod for dual-side guidance.
This specific configuration includes a magnetic piston (-S) for use with AirTAC CMSE reed and DMSE solid-state electronic sensors, which seat cleanly into the extruded aluminum barrel's sensor grooves on both sides. The rods are constructed from SUS304 stainless steel (code B) for superior corrosion resistance. It features adjustable air cushioning at both ends (36 mm cushion length) to decelerate the load near stroke end, but note that this cushioning does not lock or hold the load if air pressure is lost.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX325S Is Used
Symmetric Transfer
Drives a dual-sided transfer carriage where equal push and pull forces are required to maintain smooth, balanced motion without sudden acceleration changes between stroke directions.
Anti-Rotation Slides
Guides heavy linear slides using the twin rods exiting both ends, preventing the load from twisting or rotating during transit, which is critical for precision handling.
Rear-Rod Sensing
Utilizes the rear rod end to mount a secondary cam or position flag, triggering external limit switches or sensors away from the primary workspace contamination zone.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX325S the Right Cylinder?
Select this 100mm bore when an application demands symmetric thrust and high bidirectional force, as it provides 3681 N each way at 0.5 MPa (or 5153 N at 0.7 MPa). If your mechanism requires less force, stepping down to an 80mm bore drops the both-way output to 2268 N at 0.5 MPa, whereas a 125mm bore increases it to 5734 N. The double-rod design is chosen over a single-rod SAI when the load needs strict anti-rotation guidance or when a secondary mechanism must be driven from the rear rod.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. It uses a G1/2 port (PT tapered thread type) and supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting the FB, CA, CB, and CR variants used on single-rod SAI models). Because the stroke is 325mm, the long unsupported rod length increases the risk of side-load and rod-bearing bending; always use an external guide to support the load and prevent premature wear.

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 SAID100 Double Rod Cylinder SAID100BX325S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the force is equal in both directions. It provides 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes, it is an extruded aluminum profile cylinder built to ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a G1/2 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
