Tapered roller bearing 30309. Under GOST the same bearing is designated 7309.
C, C₀, m and limiting speed 5,300 rpm: Z&S data. Another brand publishes its own figures, so compare them against that brand’s catalogue.
Frequently asked questions
What is 7309?+
It is the same bearing under GOST 3189-89: 7309 corresponds to the ISO base 30309. Size 45 × 100 × 27.25 mm, a full equivalent of 30309.
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.
