Product Description
Shimano Curado 300K / 301K Ceramic Hybrid Spool Bearing Kit (ABEC 7)
Max out the casting potential of your Curado 300K with our premium ABEC 7 Ceramic Hybrid upgrade. This kit is designed specifically for the larger spool of the 300K, providing a faster "start-up" speed for launching heavy baits with less effort.
Why upgrade the 300K? The stock stainless bearings are built for durability, but they carry more rotating mass friction. Our Si3N4 Ceramic balls are 60% lighter and significantly harder than steel, allowing your spool to accelerate faster and maintain higher RPMs during the cast.
Kit Includes:
-
(1) 3x10x4mm Bearing: Fits the removable palm-side plate.
-
(1) 5x11x4mm Bearing: Fits the frame/tension knob side.
Performance Features:
-
Precision Grade: ABEC 7 for ultra-tight tolerances and smooth rotation.
-
Corrosion Protection: 440C Stainless Steel races with Silicon Nitride (Si3N4) ceramic balls—perfect for brackish or coastal use.
-
Easy Install: This is a "drop-in" upgrade. No specialized tools are required for the 300K spool bearings as neither bearing is trapped behind a spool pin.
