Ballast pump bearing size
I was in the process of refreshing one of my pumps and the bearing is getting a little noisy. Does anyone know what size it is?

I was looking on the page below but don't know the size.

Not sure of the size, but the only one that looks like bearing used in the ballast puppy pump is this one.

At 5 bucks it's worth a try.

Cool, for $5 bucks I ordered one yesterday just to see if it might be the right one.

Any luck rebuilding pump?

I have one going out!

I don't think that is the right bearing, It looks like a 6001

I rebuilt a Jabsco ballast pump a few years ago, and when i bought the bearings, i had to get a few extras to make up a minimum order value.
I still have 1 sitting in my drawer ;) NSK part# is 627z. Now it was several years ago, but I'm pretty sure this is the correct bearing. Only cost me about $3 each if i remember correctly. I assume you have stores in the States that specialize in bearings and seals. Bearing dimensions are:
22mm od
7mm id
7mm thickness.

Well if that is the correct part number its still pretty cheap.

Well the review on Amazon wasn't the greatest for that part. Shipping is $9.95 so one bearing is $20 and 2 would be $30 (shipped) which is the price I recalled. The review pretty much sealed the deal for me on not going with this part.

Ordered two bearings, made in Indonesia, received them 1 day apart costing me 2x shipping... , the bearing fell apart after 3 days of use, hopefully my second one lasts longer.. I don't want to keep replacing these for my motor. Original bearings in my motor.. lasted 10+ years..

I found a guy selling them for 12 for 10 bucks. Said he didn't know what they went to so figured I'd take a chance on them.

Here's 8 for 9 bucks.

I'm not sure if they are the correct size but I'll let you know when I get them.

Most common cause of early bearing failure is bad installation technique. I would try to find a local industrial supplier that stocks bearings. These should be off the shelf for around $5-$10.

That's what I did with the place in Grand Rapids MI. No luck there. If someone can find something that works I have two pumps that need bearings and two pump housings that need seals. Would love to rebuild them as spares.
