Steel bearings are inexpensive and available from the high quality brands NSK and SKF. (about $15 for a single row and $50 for a double row)

Hybrid ceramic bearings apparently have an excellent reputation; you will need to do some research if you want to avoid Chinese bearings. Costs seem about triple that of steel.

IMHO...

The IMS Solution is best retrofit for single row cars because plain bearings do not fail catastrophically as ceramic and steel ball bearings do when they collapse.

The Gen 2 Single Row Pro IMS Retrofit is the next best option for single row cars because its design allows it to carry loads almost as high as dual row bearings

Ceramic ball bearings are the third best replacement for single row cars and the best option for dual row cars because ceramic balls last longer than steel ones on tough operating environments.
