Frequently asked questions
What is 27308?+
It is the same bearing under GOST 3189-89: 27308 corresponds to the ISO base 31308. Size 40 × 90 × 25.25 mm, a full equivalent of 31308.
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.
