Technology Features of Shimano 2024 EXSENCE BB 4000MHG
HAGANE
“HAGANE” is more than just a material name; it’s a design philosophy centered around creating reels that offer unmatched longevity and smoothness. The term "HAGANE" itself, which means "steel" in Japanese, symbolizes strength and resilience. However, in Shimano's context, it transcends traditional interpretations, representing a suite of advanced technologies aimed at enhancing performance and durability. In other words, when they say "HAGANE", they do not actually mean that HAGANE(= steel) is used. “HAGANE” promises robustness that can be used with peace of mind even in the harshest of conditions, an unchanging, exquisite winding feel, and winding power that exceeds the imagination."HAGANE Gear" or "HAGANE Body" is Shimano's engineering concept and philosophy.
MICRO MODULE GEAR 2
The gear teeth surfaces in the MICRO MODULE GEAR 2 are finer and mesh more closely together than traditional gears, resulting in minimal power loss and a smooth, powerful winding experience. Additionally, the increased number of meshing teeth provides greater strength compared to conventional gears. This unique Shimano gear system achieves a balance of smoothness and durability.
X-SHIP
X-SHIP features an enlarged drive gear, optimal positioning of the pinion and drive gears, and two-point support for the pinion gear with bearings. This robust gear engagement maintains smooth and efficient reeling even under heavy loads.
SILENT DRIVE
SILENT DRIVE involves a comprehensive redesign of the entire body and drive-related components, meticulously eliminating minute gaps, play, and vibration between parts. Areas of improvement include the drive gear, worm shaft, worm shaft pin, worm shaft gear, and slider gear, among others. This results in a new level of smooth rotational performance and a quiet, refined reeling experience.
X-PROTECT
X-PROTECT provides robust protection against water ingress into the reel by combining a labyrinth-structured waterproof wall with special water-repellent grease. In small to medium-sized spinning reels, which require lighter rotation, a non-contact structure is emphasized to maintain rotational lightness. This high waterproof performance is achieved by combining traditional water-repellent treatments with a labyrinth structure that prevents water penetration without direct contact. This technology is applied to areas such as the stopper bearing and line roller.
For larger spinning reels that require higher waterproof performance, a contact-type waterproof structure is used. Low-friction seal materials physically block seawater entry paths, achieving high waterproof performance while minimizing rotational resistance. This contact-type waterproofing is applied to the stopper bearing and line roller, with the stopper bearing achieving an IPX8 waterproof rating.
G FREE BODY
The G Free Body relocates the sliding functional parts needed for spool movement to the upper part of the reel body, bringing the reel's center of gravity closer to the angler's hand. This design enhances the feeling of unity with the rod, making the reel feel lighter. It also reduces casting fatigue and improves rod handling.
AR-C SPOOL
The AR-C Spool, used in Shimano spinning reels, features a special spool ring shape. The inclined spool edge creates moderate friction resistance, leading to a streamlined line release effect. This design minimizes line troubles while achieving excellent casting performance.
LONG STROKE SPOOL
The Long Stroke Spool features a design that extends the width of the spool's line-winding area. This reduces line reduction during the latter part of the cast, contributing to improved casting feel and increased casting distance.
CI4+
CI4+ is an advanced material used in Shimano reels. It is a reinforced carbon fiber composite that is lighter and stronger than conventional materials, providing increased rigidity and reducing weight, which enhances the overall performance and sensitivity of the reel.
RAPID FIRE DRAG
The Rapid Fire Drag allows for significant changes in drag force with each rotation of the drag knob. This function is particularly effective in situations where quick drag adjustments are needed, such as when stopping a fish near structure or when a sudden surge occurs in fighting with a fish.
SA-RB
A-RB bearings feature a special anti-corrosion treatment that significantly improves their rust resistance. The SA-RB takes this further by sealing the sides with anti-corrosion materials, greatly reducing salt crystallization and salt damage inside the bearing.
ONE-PIECE BAIL
The ONE-PIECE BAIL is a seamlessly molded bail with no joints. This design significantly reduces the likelihood of the line getting caught where the line roller and bail meet, minimizing line-related issues.
