Premium grade bearings featuring rubber seals. This type of seal is much better at protecting the bearing from dust and water. Grade Bearings have higher temperature capability as well as lower noise and better vibration handling leading to longer overall life. It has good physical properties against different types, can avoid cylinder liner fuzzing, oil-free and self-lubricating, good sealing, not easy to leak, long life, and improve work efficiency. Light weight about 15% of the weight of bronze, reducing movement loss, saving mechanical power, static and dynamic friction. Fit for 1987-2006 Yamaha Banshee 350 YFZ350.
