PROBLEM TO BE SOLVED: To provide a connection type double-row rolling bearing having a good assembling property and high flexibility at a low cost. SOLUTION: Annular grooves 3 are provided at both end sections of the outer diameter faces of the inner rings 2 of adjacent single-row rolling bearings 1, and inward flanges 5 provided at both ends of a polyamide resin connecting ring 4 with the bending elastic modulus of 40,000 kgf/cm2-100,000 kgf/cm2 are inserted into two annular grooves 3 on the adjacent side of the inner rings 2 to integrally connect the single-row rolling bearings 1. The fastening force of the connecting rings 4 is sufficiently secured, and the double-row rolling bearing can be easily assembled without damaging the connecting rings 4.
