The 4203ZZ is a deep groove ball bearing supplied by DALUO under our own designation. It is dimensioned to the 17x40x16 mm envelope (bore 17 mm, outer 40 mm, width 16 mm). Each unit is produced to the original mounting and load envelope, so it drops straight into the applications the 4203ZZ was designed for.
