Factory-Links SAK-Y-300 Swingarm Bearing Rebuild Kit for Yamaha

The Factory-Links SAK-Y-300 Swingarm Bearing Rebuild Kit provides a complete OEM-quality solution for restoring your Yamaha motorcycle's swingarm to factory specifications. This comprehensive kit contains all the precision-engineered components needed for a complete swingarm bearing overhaul.

Premium Components Include:

• Heavy-duty thrust needle bearings designed for high radial and thrust loads
• Precision-turned, induction-hardened pivot pins manufactured from SAE52100 bearing steel (hardened to HRC60+)
• Zinc-plated steel collars precision-turned and hardened to HRC48
• Nitrile butadiene rubber dust seals molded to exact OEM specifications
• Full complement drawn cup needle bearings with internal clearances optimized for off-road racing conditions

Engineering Excellence:

Factory-Links designs their swingarm kits specifically for off-road applications where high impacts and extreme loads are the norm. The heavy-duty needle bearings provide superior performance compared to cheaper POM solutions, offering a significantly lower coefficient of friction between the swingarm and frame. All components are manufactured to meet stringent OEM quality requirements for materials, dimensional tolerances, hardness, and surface finish.

Each component is precision-ground and finished to restore your bike's swingarm pivot to its original condition as specified by the manufacturer. The dust seals prevent abrasive particles, corrosive moisture, and other contaminants from compromising bearing performance, ensuring long-lasting reliability in harsh riding conditions.
