Product Description
Shimano 10BGC Ball Bearing (RD10463)
The Shimano 10BGC Ball Bearing (RD10463) is a high-performance, shielded stainless steel bearing engineered to provide ultra-smooth rotation and long-term durability for Shimano spinning and conventional reels. As a genuine OEM component, this bearing is often utilized in high-load areas of the reel, such as the pinion gear support or the drive gear, where precision is critical for maintaining mechanical alignment.
This bearing is designed to withstand the corrosive nature of saltwater environments while minimizing friction. If your reel has developed a "gritty" feel or a faint humming noise during the retrieve, it is likely that a bearing has become compromised. Replacing it with an authentic 10BGC restores the effortless, "like-new" performance of your fishing gear.
