Best Radial Ball Bearing

16 Pack 4 Colors Fidget Spinner Bearing and Cap Replacement Set, Chrome Steel Bearing Balls, High Speed 13mmx7mmx4mm Bearings Single Sealed Small Bearings for Fidget Spinner

【16PCS Bearings + Caps Set】 Includes 16x MR137 precision high-speed ball bearings with blue plastic seals and 16 pairs of ball bearing caps in four bright colors (diameter: approx. 2.1cm). MR137 Steel Ball Bearing size: I.D. (inner diameter) =7mm, O.D. (outer diameter) = 13mm, Thickness: 4mm..
【Premium Quality】 The bearings are made of high-quality stainless steel and plastic for durability and deformation resistance under heavy loads. Inner and outer races are machine polished for smooth, high-speed rolling. This bearing provides higher speeds, precision, and durability, reducing replacement and maintenance costs..
【Radial Ball Bearings】 MR137 bearings are sealed on one side to protect the equipment against contaminants such as dust and water and retain lubrication. Stainless steel races ensure durability and corrosion resistance. Single row radial ball bearings support applications with radial and axial loads..
【Wide Application】 Caps made with ABS plastic are lightweight and durable, compatible with MR137 bearings. With easy-to-install components, this bearing is perfect for a wide variety of applications, including fidget spinners, skateboards and other DIY projects. Use as replacement when the original caps and bearings are lost or ....
