YSA 205-2FK-Insert bearing-FGFA bearings

YSA 205-2FK 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.

Dimensions

d	20 mm	Bore diameter of sleeve
D	52 mm	Outside diameter
B₁	35 mm	Width of sleeve
B	24 mm	Width of inner ring
C	15 mm	Width of outer ring
d₁	≈33.74 mm	Outside diameter of inner ring
d₃	38 mm	Outside diameter of lock nut
s₁	20.25 mm	Distance from locking device side face to raceway centre
Value specified for s₁ is approximate and before the sleeve is driven into the bearing bore (sleeve and inner ring bore at starting position).
