    About the bearing

    D 90d 40B 23
    d×D×Bsize 40 × 90 × 23mm

    Frequently asked questions

    How does 2RS differ from ZZ?

    2RS has rubber seals that touch the inner ring and keep out dust and water better, which is the usual choice for field machinery. ZZ has metal shields that do not touch, allow higher speeds, and protect against dirt less well.

    What is 180308?

    It is the same bearing under GOST 3189-89: 18 — contact seals on both sides, 0308 corresponds to the ISO base 6308. Size 40 × 90 × 23 mm, a full equivalent of 6308-2RS.

    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.
