Product Description
Shimano 10CCN Roller Clutch Inner Tube (BNT4867)
The Shimano 10CCN Roller Clutch Inner Tube (BNT4867) is a critical precision component of the Instant Anti-Reverse (IAR) system in Shimano baitcasting reels. This hardened steel sleeve sits directly on the drive shaft and serves as the internal race for the roller clutch bearing.
When you turn the handle, the inner tube rotates within the rollers; the moment you stop or a fish pulls back, the rollers wedge against this tube to provide an instant, "zero-play" stop. Because it is a high-friction surface, the inner tube can develop microscopic grooves, flat spots, or pitting from salt and old grease. If your reel has developed "back-play" or the handle slips occasionally, replacing this tube—along with a thorough cleaning of the roller bearing—is the standard factory fix.

Pro Tip: During installation, the surface of the inner tube must be kept extremely clean. A single drop of very light reel oil is usually sufficient; using heavy grease on this part can cause the roller bearing to "slip" in cold weather, resulting in anti-reverse failure. For the exact orientation of the tube and the washers that sit above and below it, refer to the PDF schematics at www.reelschematic.com.
Key Features
-
Zero-Play Engagement: Restores the "solid" feel of the handle by providing a perfect friction surface for the roller bearing.
-
Extreme Hardness: Heat-treated steel prevents the rollers from "tracking" or wearing ruts into the tube under high drag pressure.
-
Corrosion Resistance: High-grade stainless alloy is designed to resist the pitting that causes anti-reverse slipping.
-
OEM Precision: Machined to exact inner-diameter tolerances to ensure it fits snugly on the drive shaft without wobbling.
