CYS 30 FM-Insert bearing-FGFA bearings

CYS 30 FM Insert bearing with pre-fitted rubber seating 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.
