AirTAC SAID Series Double-Rod Cylinders
The AirTAC SAID series is a double-rod ISO 15552 air cylinder spanning 32-200mm bores, delivering equal push and pull force for applications requiring anti-rotation guidance and dual-end output.

The AirTAC SAID series is the double-rod (through-rod) version of the ISO 15552 SAI cylinder. A single piston drives a rod out of both end covers while remaining double-acting. Because a rod occupies both sides of the piston, the effective annulus area is identical in both directions, meaning push and pull force are equal. The series spans 9 bores from 32 to 200mm, with standard strokes reaching up to 1500mm on the largest sizes.
Force output matches the SAI pull-side figures. At 0.5 MPa the force spans 345N on the 32mm bore up to 15080N on the 200mm bore. At 0.9 MPa the range extends from 621N to 27141N. The shared design includes variable air cushions at both ends that decelerate the piston near stroke end. Note that this cushion only decelerates; it does not hold position or lock the load if air pressure is lost.
SAID cylinders operate on filtered 40um air at 0.15-1.0 MPa, with speeds from 30-800mm/s on smaller bores and 30-500mm/s on 125-200mm bores. Mounting options include Basic, FA, LB, TC, FTC, TCM1 and TCM2. The rear rod end can drive a second mechanism or carry a sensor cam. The SAID is the current-production replacement for the discontinued SID series.

Typical Applications
Dual-End Conveyor Transfer
Drives a conveyor pusher from the front rod while the rear rod simultaneously actuates a diverter gate, using the equal push/pull force to synchronize two mechanisms in one stroke.
Anti-Rotation Tool Guidance
The through-rod design resists torsional load and prevents the piston from rotating, guiding precision machining or clamping heads that require strict angular alignment without external guides.
Compact Packaging Cams
Uses the protruding rear rod end to mechanically trigger a sensor cam or secondary packaging flap, saving space by eliminating the need for a separate external actuator on the back end.
Heavy Material Handling
Leverages the 125-200mm bore sizes to move heavy pallets or industrial fixtures, utilizing the 15080N force at 0.5 MPa and the robust ISO 15552 footprint for stable high-load transfer.
How to Choose the Right Model
Choose the bore size based on your equal push and pull force requirement: the 32mm bore provides 345N at 0.5 MPa, while the 200mm bore provides 15080N. Select the stroke length up to the 1000-1500mm maximums depending on bore size. Confirm the port thread (PT or G, ranging from G1/8 to G3/4) and choose a mounting style from the available SAI subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Add the -S magnet option if you need CMSE or DMSE position sensors.
Step out of the SAID series to the SAI family if you only need a single rod and standard unequal push/pull forces. For loads requiring held position without air pressure, switch to the SAIL air-released lock cylinder, as the SAID air cushion is not a brake. For applications needing adjustable stroke limits, use the SAIJ series. Always confirm from the datasheet that rear-rod clearance is available, as the overall length is longer than a standard SAI cylinder.

Frequently Asked Questions
The SAID series spans 9 bores from 32 to 200mm. Because it is a double-rod cylinder, push and pull forces are equal. At 0.5 MPa the force spans 345N to 15080N. At 0.9 MPa it spans 621N to 27141N. Maximum standard strokes are 1000mm for bore 32, 1200mm for bores 40-50, and 1500mm for bores 63-200.
The SAID is a double-rod (through-rod) version of the single-rod SAI cylinder. It provides equal push and pull force and allows a second mechanism or sensor cam to attach to the rear rod. The SAID is also the current-production replacement for the discontinued AirTAC SID series.
No. The SAID is a double-acting air cylinder with variable air cushions at both ends. The cushion only decelerates the piston near the stroke end; it does not lock or hold the load. If load holding is required, a mechanical lock, rod brake, pilot check valve, or the AirTAC SAIL air-released lock cylinder is needed.
The SAID shares the ISO 15552 mounting interface and barrel with the SAI series. Available mounting options include Basic, FA, LB, TC, FTC, TCM1 and TCM2. Ports are PT or G thread, ranging from G1/8 on the 32mm bore to G3/4 on the 200mm bore. Always leave rear-rod clearance as the overall length is longer than a standard SAI cylinder.
