Hi,
I have fitted similar 7002 bearings are fairly common in the automotive industry used in idler bearings and spigot bearings. They cost about $10. Maybe worth checking specs
You could always order the same ones for China for $3ea plus Shipping Buy 7002C angular contact ball bearing, 15X32X9mm angular contact bearing, 7002 bearing, 15X32X9mm 7002C 7002AC single-row angular contact bearing wholesale and retail at Aliexpress.com
