Redefine innovation to conquer the impossible. The iconic heritage of the Stella family embodies this mindset with the debut of the new Stella SW D, designed to elevate angler performance through industry-leading Shimano reel technologies. Built upon the Shimano legacy of cold-forged HAGANE gears for added strength, new InfinityXross technology extends the gear tooth horizontally to distribute load across the gear tooth more evenly for unequaled gear durability. The debut of Shimano’s new XX Tough Drag technology modifies the reel’s drag construction by moving the upper washer to the top of the spool and significantly increasing the drag washer size.

The result: Greater drag durability and less heat accumulation for added performance. Combining new spool and rotor innovations with proven Shimano technology increases casting and reeling performance with improved line management. Shimano’s new InfinityLoop technology leverages asymmetrical worm shaft grooves that change oscillation speeds depending on the direction of the spool movement to produce a more even line lay and beautiful winding shape. To the angler, InfinityLoops technology increases casting distance and eliminates unwanted drag spikes for a heightened fishing-fighting performance. The combination of the new Anti-Twist Fin an elastic polymer on the underside of the roller with a redesigned drag knob and spool lip enhances reeling performance with superior line management.

Conquer the Impossible: The new Stella SW has arrived.

Features:

• Hagane – A reel design concept created to withstand continual use and extreme abuse. HAGANE is an innovation with built-in toughness and durability that works alongside Shimano’s precision engineering. HAGANE is for all anglers.
• Hagane Gear – With amazing strength and durability, the HAGANE Gear is at the very heart of most Shimano reels. Shimano, through the application of state-of-the-art technologies, gives anglers the long-lasting smoothness and pleasure that is felt when anglers first use a reel, over and over again. No cutting work is applied to the teeth of the drive gear during fabrication, instead the entire surface is calculated in minute detail by special 3D-design and then formed by Shimano’s cold-forging technology. The result is assured resilience. HAGANE Gear is the fruit of Shimano’s inexhaustible pursuit for durability the strength and power of forged metal continues to represent the fundamental concept of Shimano reels.
• Hagane Body – The HAGANE Body is a metal reel body with high rigidity. The body rigidity and impact resistance virtually eliminates body flexing on the reel while fighting fish. The result transforms the anglers actions directly into cranking power, increasing efficiency through strength.
• X-Ship – X-Ship provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This allows the gears to stay in the same position under the heaviest loads. The added benefit of X-Ship technology is that friction between the spool shaft and gear are eliminated. This further benefits anglers with enhanced casting performance and casting distance of lighter lures.
• X-Shield – By providing dependable sealing structures and gaskets at 12 crucial locations throughout the reel body, Shimano is able to create a water-resistant structure that is highly reliable and durable while ensuring that it can hold up when used in extreme saltwater conditions.
• Infinity Drive – The Infinity Drive structure is an advanced structure that creates exceptionally light winding. The main shaft, which had previously been supported by the pinion gear, is now supported by a new and unique low-friction bushing that significantly decreases frictional resistance. In addition, the main shaft has undergone a proprietary surface treatment and special processing to drastically reduce rotational torque, constructing a reel that can actively wind even under heavy loads.
• InfinityXross – InfinityXross provides superior gear durability through industry-leading design and cutting-edge manufacturing technology. Advancements in the gear tooth design improve the surface contact and meshing between the drive gear and pinion gear. This revolutionary design efficiently distributes the load placed on the gear tooth surface across a wider area to prevent damage from stress points while significantly improving overall gear durability.
• Cross Carbon Drag – The Cross Carbon Drag material provides a wider range of drag settings compared to traditional drag materials. The Cross Carbon Drag provides the smoothest Shimano drag performance ever while providing anglers with increased durability.
• X-Protect – X-Protect provides high-level water resistance without sacrificing light gear and rotor rotation. By combining Shimanos water-repellent coating with a water-channeling labyrinth construction, X-Protect provides added durability in tough conditions.
• Heatsink Drag – The Heatsink Drag is a revolutionary structure located at the bottom of the spool that helps achieve overwhelming drag performance and improved durability. The Heatsink Drag dissipates heat outside of the spool by about 50% to reduce the drag-force drop that is caused by friction and heat. To further improve performance, the Heat Insulation Sheet dampens the heat flowing to the line on the spool and reduces line temperature by 30% for increased dependability during long fights.
• Rigid Support Drag –By strengthening the spool support of the main shaft, the play and fluctuation of the spool during drag operation are suppressed. The Rigid Support Drag allows smooth and consistent drag delivery, even under high load.
• Silent Drive – SilentDrive technology benefits from a total redesign of all functional parts focused on the drive gear, worm shaft and other parts. The goal: remove unnecessary noise and vibration. In doing so, the overall tolerances are improved to a micron level, ultimately creating an overall quieter and smoother reel operation.
• InfinityLoop – InfinityLoop technology delivers exceptional casting performance by drastically reducing friction on the line leaving the spool. Advancements in the internal structure and design extend the spool’s oscillation to enable the spool to move up and down at an extremely low speed. This technology creates a precise winding pattern with less overlap that significantly reduces friction as the line leaves the spool during a cast. The result is smooth and exceptional casting performance, especially of light lures.
• Anti-Twist Fin – Shimano designed the Anti-Twist Fin for enhanced line management resulting in more effective fishing. The flexible polymer fin is installed near the line roller. This maintains line tension to reduce sagging and prevents the line from falling off the bottom of the spool or wrapping around the spool in an uneven manner.
• S A-RB Bearings – “S A-RB” Bearings are put through the same process as Shimano’s A-RB bearings but feature shields on both sides of the bearings. These shields reduce the possibility of salt or sand inhibiting rotation of the bearing.
• One-Piece Bail – One-Piece Bail allows the line to travel unimpeded to the line roller. The seamless design reduces friction and decreases the chance of tangles or the line catching on the bail arm.
