Product Description

SHIMANO 104PP BALL BEARING (RD13274)

Restore Drive Train Smoothness

The Shimano 104PP Ball Bearing (Part No. RD13274) is a premium, genuine OEM stainless steel bearing used in a wide variety of Shimano spinning and baitcasting reels. Most commonly utilized as a Drive Gear Bearing (supporting the main gear on the side plate) or a Pinion Gear Bearing (supporting the pinion shaft), this component is critical for maintaining the reel's rigidity and cranking smoothness.

Measuring 7x11x3mm, this bearing is engineered to withstand high rotational speeds and radial loads. If your reel feels "rough" when turning the handle, makes a growling noise, or exhibits play in the main gear, a worn 104PP bearing is often the cause. Replacing it with this authentic part ensures tight tolerances and restores the silent, buttery feel of your high-end Shimano reel.

Installation Tip: Because this is a 7x11x3mm bearing, it is often identical in size to other bearings in the reel but may have different shielding (Open vs. Shielded). Always verify the specific "RD" number to ensure you are installing the correct seal type for that location (e.g., internal gear box vs. exposed line roller).
