BEARINGS TRAINING SG 9

SG9 bearings combine a high level of precision with a silicone/grease blend to protect the bearings from the elements and allow the wheels to spin faster while keeping them well lubricated. The higher the number at the end of the bearing, the higher level of precision, tolerance, and speed. Includes 16 bearings. Great performance and durability from the 7-ball bearing design. Reduced friction and increased speed are two of the main benefits of the silicone/grease blend. Metal shields prevent impurities from entering the bearings for consistent performance and spin.
