Here’s the link:

If the link ever goes dead, the pulley part number is HY-CH302, and the bearing part number is 30BD4720.
Getting ready to do this conversion and wanted to swap the bearing, but that part number only brings up other Chinese bearings. Went through NSK's catalogue and it doesn't seem like its an active part number. I even tried finding a replacement for the NACHI that comes on the RX-8 pulley and that part number doesn't pull up anything either.

Unfortunately it has been discontinued, you’ll have to try eBay and find new old stock. Unless someone else can find a pulley that utilizes a different size bearing but the same diameter pulley that is 6 rib. Worse case, you’ll have to use a Chinese bearing until one pops up for sale.

Wanted to wait till my pulley came in to confirm everything fit properly, but found some NACHI 30BG4720-2DL's on Ebay. Picked up 2 just so I have a spare should I need one in the future.

So I have a question, I have my RX8 AC compressor, the only other thing on my serpentine belt is the alternator. Would it be easier to just swap the eshaft pulley and alternator pulley to the RX8 style since I don't necessarily trust ordering from allibaba? I'll be using the JDL side mount for the alternator and AC.

I just did the same using your recommendation and ordering the pulley without the bearing recommended by Creepenjeepen. Works perfectly with 2 shims (amazon uxcell m6 x 12 x.1mm). 2 pulleys were $85 shipped (15 each pulley, 50 shipping, 5 bank charge). Guangzhou Huahui Parts was very easy to work with and professional. I received the pulleys in about a week. Someone willing to outlay the funds could make a kit for cheaper by buying bulk parts to save on shipping.

I found this DENSO compressor that comes with a 6-rib belt. A perfect alternative to the 4-rib RX8 compressor, alleviating the need to swap clutch pulleys.

The 6 rib compressor is from a Toyota Corolla - ZZE122R 1.8L Petrol -1ZZ-FE - 2001 - 2007

Compressor Details

Brand - DENSO
Model - SCSA06C
Part Number - CM1680
Voltage -12V
Pulley -Type 6PV
Pulley - Diameter 98mm
Ports - Pad
Refrigerant Type - R134a


Where to order this compressor? Seems that RockAuto doesn’t sell it.
