Key Features of Shimano Spheros SW

“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.

INFINITY DRIVE

(Only equipped in #5000, #6000, #8000)

INFINITY DRIVE is an advanced evolution of the traditional X-SHIP structure. By making the main shaft, which was previously supported by the pinion gear, non-contact and supporting it with a special low-friction bushing, sliding resistance is greatly reduced. Additionally, special surface treatments and processing have been applied to the main shaft itself to further reduce friction loss. These enhancements enable powerful winding even under high load conditions.

X-SHIELD

(Only equipped in #5000, #6000, #8000)

Shimano's waterproof mechanisms include "Core Protect," "X-Protect," and "X-Shield." "X-Shield," used in the SW series, is a waterproof mechanism designed to prevent water ingress by sealing gaps with special seals. Strong sealing is applied at various points, including the body-lid interface and the spool-drag knob contact area, to block water entry paths. This ensures high reliability and durability in the harsh conditions of SW game fishing. While completely sealing gaps increases the friction coefficient during reel rotation, potentially affecting the smoothness of the reel, the primary focus is on maximizing waterproof performance.

X-PROTECT 

(Only equipped in #5000, #6000, #8000)

X-PROTECT combines a labyrinth structure with special water-repellent grease to provide strong protection against water intrusion into the reel's interior. The system is designed with a non-contact structure to maintain light rotational performance. In addition to traditional water-repellent treatments, the labyrinth structure effectively blocks water entry, ensuring high waterproof performance without direct contact. X-PROTECT provides robust protection for the spool-side bearing of the drive gear shaft. Additionally, a waterproof barrier is placed inside the spool to further reduce water intrusion into the spool shaft bearing.

CORE PROTECT

(Only equipped in #3000, #4000)

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

(Only equipped in #3000, #4000)

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.

A-RB

(Only equipped in #5000, #6000, #8000)

A-RB bearings feature a special anti-corrosion treatment that significantly improves their rust resistance.

SA-RB

(Only equipped in #3000, #4000)

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.
