Othmro SMR137ZZ Deep Groove Ball Bearing P0 7x13x4mm 440C Stainless Steel Bearings 2pcs

Description: Deep Groove Ball Bearings Ball bearing, in which the rolling elements are spherical balls. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. (Reducing the friction of certain moving parts by replacing sliding friction with rolling friction) With small friction and high-limit speed, cost-effective and require little maintenance Used in parts such as steering, engine, driveline, and driveshaft. Such as skateboards, ect. With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance. Stainless steel bearing features stronger rust and corrosion resistance ability to withstand destruction caused by humidity and some other media. NOTE? Please refer to the picture and select right type of bearings before your order.
