Product Description

SHIMANO 1009A LINE ROLLER (RD19959)

Restore Factory Smoothness with Core Protect

The Shimano 1009A Line Roller (RD19959) is a complete, genuine OEM replacement assembly designed for premium Shimano spinning reels. Featuring Shimano's Core Protect technology, this line roller integrates the bearing and the roller unit into a single, sealed component. This design provides superior water resistance and ensures long-lasting, smooth rotation under load, essential for preventing line twist and protecting your mainline during high-pressure fights.

Because the bearing is integrated into the roller body, this part cannot be disassembled. If your current line roller sounds noisy, feels rough, or has seized due to saltwater intrusion, replacing the entire RD19959 assembly is the correct solution to restore your reel's original performance.
