UCX13-Insert bearing-FGFA bearings

UCX13 Insert bearing with set screw locking and extended inner ring

Insert bearings (commonly known as Y-type bearings) are versatile mechanical transmission components suitable for multiple applications. Featuring a compact design, their core advantage lies in straightforward installation—requiring no complex mounting structures, they can be directly inserted into bearing housings or equipment mounting holes, significantly reducing assembly time and simplifying routine maintenance.
