    About the bearing

    D 72d 30B 19
    d×D×Bsize 30 × 72 × 19mm
    mweight 0.35kg

    Deep groove ball bearing 6306-ZZ, design 2Z: metal shields on both sides. Under GOST the same bearing is designated 80306.

    M: FAG data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

    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 80306?

    It is the same bearing under GOST 3189-89: 8 — metal shields on both sides, 0306 corresponds to the ISO base 6306. Size 30 × 72 × 19 mm, a full equivalent of 6306-ZZ.

    Will 6306 2Z C3 fit instead?

    Same size, clearance greater than normal. C3 is used where the bearing runs hot or sits on the shaft with an interference fit. If the old bearing is not marked C3, take this one.

    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.
