I replaced the bearings for Idler and tensioner pulleys, and only 20K miles later, got stranded on Highway, midnight.
Not recommended.

this is why you want only Koyo, NTN, or NHK bearings and find the ones made in Japan!

bearings are highly counterfeited, so be sure to go to the manufacturers webpage and obtain the list of authorized dealers

Tsk, tsk, tsk...there's also this unknown small company called SKF.

LScowboyLS

those are for Volvos and Saabs

And we all know how good those cars are...er...make that were.

The bearings

Greg5OH

Ordered 6301-2RS and I should say it's narrower than original BD20-15DUL part, and besides it only seems to have one row of ***** inside

Unfortunately, the industry only makes 12x37mm bearings (ID/OD respectively) being 12mm wide and with single row of bearings. The 2301 series is 12x37mm two-row and 17mm wide but I don't know if it's applicable by other parameters

The original bearing has a sleeve depressed into its internal diameter, so it's actually two parts.

Most of the aftermarket bearings for the idler pulley don't have that inner sleeve which actually balances the pulley on the engine. I've been searching and may have to end up just buying a OEM pulley from the dealer online.

we just knocked the inner sleeve out and reused it, no problem

sorry, I just saw this.. it was a Toyota pulley (off a Lexus LX470 with a TRW supercharger,) we found the idler but no bushing (looked like below)

For what it's worth . . . .

I must have missed something in this post that says there are actually TWO (2) bearings in the Tensioner Pulley.

The correct Part Number is: "6203 2RSJ". (NAPA part "BRG 62032RSJ", an SKF bearing).

Apparently it is a common bearing used for alternators, power steering, clutch pilot, generators, A/C compressors, etc.

Remember to buy TWO (2) of them.

Awesome, thanks! My supplier lists it at clightly lower price than the assembled pulley. My original pulley had one 2-row bearing and a sleeve pressed into it. Should I keep the sleeve or "6203 2RSJ" already has the proper inner diameter?

drgerry

No, keep the sleeve. You will have to re-use it. The bearings are two separate items.

Yeah, you can get them for $6-$8 online, but I have to have it TODAY. Can't run the car without it. And I didn't know the correct part number until I took the old one out.

I never could find one with both bearings and sleeve in a single unit. You would think that the part number "6203DUL18", that the DUL part meant Dual?.(guess that makes too much sense)
