SF635 Bearing Product Overview & Core Advantages
The SF635 is a metric single row deep groove ball bearing designed for high-performance radial load applications. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance and durability. This open-type bearing is characterized by its compact flange design, which facilitates secure mounting and positioning. With a limiting speed of 28,800 rpm and ABEC1 precision class, it provides reliable operation for applications demanding smooth rotation and long service life.
