YSA 211-2FK-Insert bearing-FGFA bearings

YSA 211-2FK Insert bearing with tapered bore and adapter sleeve locking

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.
