SF686zz Bearing Product Overview & Core Advantages
The SF686zz is a metric miniature ball bearing featuring a single row design with stainless steel construction for excellent corrosion resistance. Its shielded (ZZ) design provides effective protection against contamination while maintaining low friction. This bearing is engineered for radial load applications and is characterized by its compact dimensions (6mm bore, 13mm OD, 5mm width), making it ideal for applications where space is limited. Manufactured to ABEC1 precision tolerances, it offers reliable performance and smooth operation in various industrial and precision instruments.
