6204RS Wheel Bearings

Seeing as I have the rim off so I can change the tire. I figured I would replace the wheel bearings seeing as they feel pretty rough. I tried finding a place that sells them, but I keep coming across Wheel bearings for Scooters..Skates..It just doesn't seem safe to use a scooter bearing.. let alone roller skate bearings. Is it the same bearing with multiple uses? Or is their a motorcycle specific 6204RS wheel bearing? The dimensions are 20mm I.D., 14MM Depth, 47MM O.T.

A 6204RS is the same bearing where ever you get it from FAG makes good ones.But I wouldnt but a sticker on your bike advertising what bearings ya got

What bike?!?!

Z1Enterprises.com sells AllBallsRacing wheel bearing kits for a variety of bikes. The kits include the oil seals. They're nice bearings.

the napa auto part # is 62042rsj

Yeah just get whatever. All 6204 sealed bearings will be the same, as long as they came from a decent bearing manufacturer. I had some NSK 6204's left over from a project, so I'm using those.

any bolt supply or bearing supply place can get or will have these in stock a very common bearing size. grab your yellow pages and let your fingers do the walking.

Thanks, I ended up going with these

No way would I put that trash in my bike!! They're made in Wuxi, China. Get QUALITY bearings, there are plenty of places that sell them. Ed

Back your accusations up. Just because they are made in china doesn't mean they are not at least comparable quality to OEM or better. I'll be more then happy to read about quality issues,premature failures, etc.

They are just not one of the established bearing manufacturers. They'll either be fine or they wont. I've never heard of the company, can't tell you anything about them.

There are many different grade bearings. Generally, you want to be running a quality bearing where the tolerances and bearing components are designed for the application.

Heat will expand components - put a bearing designed for low-rpm, low-heat in an application with high RPM and heat and you can (will) have problems. Similarly the cages on bearings are designed to take different stress loads. You can put 4 or 5 seemingly identical bearings alongside one another and not easily be able to pick out those that'll break apart under load. Brand name is about the only way to tell.

We sell the All-Balls Brand wheel bearings - and those bearings are a higher grade than generic bearings. They are the same grade as you'd find in electric motors.

There's a big difference in stress loading for roller skate bearings versus wheel bearings.

There are both bad and good product coming out of China and Taiwan - the problem is knowing the good from the bad... you pay your money, you take your chance.

Of course you are correct. I say buy them instead of a name brand and put them in your bike (not mine). You may be able to save enough money to buy a 6 pack. Whatever you do, don't buy a brand like All Balls, Timken, FAG, NSK, SKF, or Koyo. Those companies all have proven track records of superior products. These simply will not do when you can take a chance with an unknown brand of bearing that may fail and send you skidding down the highway on your ass.
