Technology Features of Shimano 2021 NASCI
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.
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.
CORE PROTECT
CORE PROTECT uses a water-repellent treatment to create a beading effect that prevents water from entering even through minute gaps. This enhances waterproofing without increasing rotational resistance. Additionally, since it is a non-contact system, it avoids wear and tear, ensuring long-lasting waterproof performance.
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.
