Technical Specifications & Details
Component: Deep Groove Ball Bearing (Special size 63/28).
Dimensions: OD: 72 mm | ID: 28 mm | Width: 18 mm.
Material: High-grade chrome steel for durability and heat resistance.
Compatibility: Fits Shineray, Bashan, Eagle, and other 200cc–300cc Chinese Quad engines.
Benefit: Precision tolerances for smooth operation under heavy-duty conditions.
Visual Compatibility: Before installation, perform a visual check. Match the 72x28x18 mm dimensions exactly with your stock bearing.
Thermal Fitting: For best results, use the "shrink-fit" method by heating the casing and cooling the bearing. This reduces the force needed and protects the bearing seat.
Lubrication: Always pre-lube with fresh engine oil during assembly to ensure immediate protection upon the first engine start.
