    Deep groove ball bearing 6203-Z, design Z: shield on one side. Under GOST the same bearing is designated 60203.

    C, C₀, m and limiting speed 24,000 rpm: KG 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 60203?

    It is the same bearing under GOST 3189-89: 6 — shield on one side, 0203 corresponds to the ISO base 6203. Size 17 × 40 × 12 mm, a full equivalent of 6203-Z.

    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.
