    About the bearing

    D 80d 25B 21
    d×D×Bsize 25 × 80 × 21mm

    Deep groove ball bearing 6405-ZZ, design ZZ: metal shields on both sides. Under GOST the same bearing is designated 80405.

    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 80405?

    It is the same bearing under GOST 3189-89: 8 — metal shields on both sides, 0405 corresponds to the ISO base 6405. Size 25 × 80 × 21 mm, a full equivalent of 6405-ZZ.

    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.
