what this bearing is, questions
Deep groove ball bearing 61903-ZZ, design ZZ: metal shields on both sides.
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.
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.
