Shimano Stradic SW B 4000 XG Reel

Shimano Stradic SW B 4000 XG Reel. STRADIC SW has been attacking the harsh sea fishing scene with its power, toughness, and waterproof performance that are comparable to those of higher-end models. Such a super practical reel has finally been renewed with the evolution of the right reel in the right place by product number. No.4000 is based on the acclaimed 23 STRADIC, introducing INFINITYXROSS, INFINITYDRIVE, and ANTITWISTFIN to pursues further comfort of use such as improved gear durability and suppression of line trouble. Each model from No.5000 to No.10,000 is equipped with X TOUGH DRAG, which achieves improved specifications in terms of durability, heat dissipation, and maximum drag force. The specifications are designed for fighting with heavy weight lures and large fish. In addition, the No.5000 and No.6000 eliminate the conventional bail auto-return mechanism to shut out trouble in casting. A total of nine items have been narrowed down to construct a series more suited to practical use along with performance that surpasses its class.

HAGANE
HAGANE is a Shimano 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
The HAGANE Drive Gear is produced by Shimano’s coldforging technology, without the need for additional machining. This delivers a longlasting smoothness, strength, lightness
and power at the very heart of the reel. Traditional diecast, machined gears are less durable under heavy loads.

MICROMODULE II
The MICROMODULE Gear II has evolved with Shimano's unique manufacturing technology and  a state-of-the-art gear-tooth surface design. The drive and pinion gear surfaces have been analyzed and updated from the ground up in Shimano's pursuit of perfection to further improve the smooth gear feeling and reduce sound.

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 increased support allows the gears to stay in the same position under the heaviest loads. X-Ship technology also eliminates the friction between the spool shaft and gear to further benefit anglers with enhanced casting performance and casting distance of lighter lures.

HAGANE BODY
The use of lightweight and rigid metals such as aluminum and magnesium firmly suppresses deflection, distortion, and torsion of the reel. This protects delicate gear meshing and enables smooth reeling.

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.

INFINITYDRIVE
INFINITYDRIVE technology is an advanced structure that produces lower friction and lighter winding. Pinion gear is supported by the spool shaft instead of the pinion gear bearing on the spool side. Rotational resistance of the gear section has been reduced without compromising gear strength.

SILENTDRIVE
The basic design of the entire body and drive-related parts were reviewed one by one to reduce minute rattles, gaps, and shaking between parts down to the smallest detail. It provides smooth and quiet reel rotation.

ANTI-TWIST FIN
Elastic fins are installed in close proximity to the line roller section. By suppressing line slack, the fins reduce the phenomenon of line dropping out of the lower part of the spool and line wrapping around the spool while the line is still twisted.

X SHIELD
The body is water-resistant equivalent to IPX8 by water-resistant seals on the body, side covers, and other parts of the body.

X PROTECT
For medium and small general-purpose spinning reels, which require lighter spinning, we focused on a non-contact structure that does not compromise the lightness of the spinning. In addition to conventional water-repellent treatment, a labyrinth structure that suppresses water penetration is combined to achieve high water-resistant performance despite the non-contact nature of the structure. It is used in the stopper bearing section and line roller section.

X TOUGH DRAG
Each washer is made of only metal and carbon to support the spool from both the top and bottom. Smooth and stable drag performance has been refined by improving heat resistance and durability.

G FREE BODY
G FREE BODY technology has been developed to shift the reel's center of gravity closer to the rod. By moving the center of gravity closer to the angler’s hand, the G FREE BODY helps to reduce fatigue and enhance casting comfort.

AR-C SPOOL
The spool has a special spool ring shape. This creates a rectifying effect on the line and realizes both suppression of line trouble and long casting performance.

LONG STROKE SPOOL
The LONG STROKE SPOOL has a longer stroke compared to conventional spool designs. It contributes to improved casting feel and distance.

CI4+
CI4 is a resin material reinforced with carbon fiber that is lighter and has a higher strength than conventional resin material. CI4+ is an advanced version of the original CI4 material.The rigidity and durability have been greatly improved from original CI4 material while maintaining the lightness of the material, making it possible to reduce the size and weight of the reel.

CROSS CARBON DRAG
The CROSS CARBON DRAG provides the smooth drag release and the  durability.

SA-RB
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 the rotation of the bearing.

ONE-PIECE BAIL
ONE-PIECE BAILallows 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.
