Features The bearing has a small axial width, a compact and stable structure, and can withstand larger loads. These bearings can provide quiet rotation and high rotation speed, thereby providing more effective support. The rolling bearing has low friction coefficient, low starting and running torsion, and relatively stable performance. The bearing is made of stainless steel, which is resistant to high temperature and corrosion. These bearings have a wide range of applications and are often used in skateboards, longboards, roller skates, etc. Specification: Item Type: Ball Bearing Material: Stainless steel Model: S625Z Size(Inner Diameter x Outer Diameter x Height): Approx. 5 x 16 x 5mm / 0.2 x 0.6 x 0.2in Package List: 10 x Ball Bearing Package List 10 x Ball Bearing
