Tapered roller bearing 30205. Under GOST the same bearing is designated 7205.

Frequently asked questions
What is 7205?+
It is the same bearing under GOST 3189-89: 7205 corresponds to the ISO base 30205. Size 25 × 52 × 16.25 mm, a full equivalent of 30205.
Can I fit another brand instead of this bearing?+
Without checking, only an exact equivalent: the size, seal, clearance and design match according to the brand’s catalogue. Positions with the same geometry differ in seal, clearance or design, and each one says so in the equivalents block. Load ratings differ between manufacturers, so for a heavily loaded unit compare C.
