These 6203 2rs (c3 clearance) are used in over 90% of all automotive idler and tensioner pulleys. I used these Nachi on Jeep wrangler, and Ford F250 pulleys, worked great in both applications. A very high quality bearing, made in Japan. The 6203 in combination with a 6304 size are also used on a Hayward pool pump, and once again have done exceptionally well (can't even hear the pump run it's so quiet now).

I bought a set of these bearings to replace the stock worn out idler and tensioner pulley bearings in my Crown Victoria. They went in very smooth and are very quiet. I definitely recommend this product to someone else.
