Nsk Bearings (2 Pack) 6203-2RS 6203DDU 6203VV Bearings 17X40X12MM Pressed Steel Cage,Deep Groove Ball Bearings

Always, always, always check for proper greasing before installing ANY imported bearings. Most Ive popped the seals off have had little or NO lubrication. Expected the same from these, but popped seal off to find them WELL greased. Not sure about the quality of the grease (I do use a moly fortified synthetic grease in all bearing apps), but any grease is better than none!

I wished I’d have done this with my old pump.

I bought these to refresh the bearings on the three pulleys of the Explorer 5.0 front dress. The tensioner and the two idlers use this same size. You will need an arbor press or hydraulic press to remove the old and install the new bearing. I used green wicking Loc-tite between the outer race and pulley ID just in case. The factory bearing are NTN 6203LU .

Items exactly as described. They are from NSK but made in Poland. Appears to be in good quality. I used 2 together to replace the bearings for a 2010 Toyota Sienna serpentine belt tensioner pulley. Let see how long they last.

No issues...great quality.

Though NSK is a Japanese brand, this particular bearing (or at least the one I received) was made in Poland, which is absolutely fine as it is still, by all outward appearances, a very nicely made bearing. DDU is the an NSK designation meaning this bearing has 2 contact type seals which is preferable in applications where there could be dirt infiltration such as a power steering pump.

Met specification and fit

Its tough to find the right bearings, but these are them for the AO Smith / Century MOTOR for the Pentair WhisperFlo WFE-6, 1.5 HP pump (355012S). Not the pool pump bearings, but the motor!!!! Works like a charm to calm that motor noise down!!

The right bearing for power steering pump Nissan Quest and great quality.

I love these bearings they hold up excellent
