Do these have sealed bearings?

I don't know. I use mine on a spin bike. I just know shimano makes great gear.

Yes they do have sealed bearings, this pedal is strong I am using everyday on my MTB and they rock!

They do not have sealed bearings. See http://www.shimano.com/publish/content/global_cycle/en/us/index/products/pedals/mountain/product.-code-PD-M324.-type-.pd_mountain.html for an exploded view. You need a special wrench to disassemble/reassemble them as well. the problem is that the tool needed costs as much or more than the pedals themselves! So unless your LBS has the tool, it is cheaper to just buy a new pair. Been using these since 2009, they are awesome, no issues.

Yes they are. I towed the trailer on a 1600 mile trip with no problems. Just make sure the trailer is square when put together, proper inflation, and you pack the bearings with a quality grease.

I am not sure if they have roller bearings but it is a great product the drawers shut very easily and very smoothly all in all it is a great buy I'm very satisfied with it

Were they still sealed? If not I'd return them. Mine did not have this. Sorry.

I'm not sure about the bearings but if I had to guess I would say Yes they are sealed. No squeaks ever, I've had the chair for 15 months. Let me tell you though, it's not that comfortable and it takes up a lot of room.

They are sealed units -- technical they should stay like that for ever. I buy them once in several months, and seem to work fine.

Yes they do. I bought them. They worked great and had the nuts. When you put them on make sure those first lug nuts are very tight. When I checked my wheels after the first couple weeks I noticed a couple had loosened.

It has a sealed bearing, but there is a place to oil it. Runs quietly. Hope this helps.

Yes. Internal bearing seemed to be of good quality. Overall, mounts work great. Although my old mounts appeared normal, I went ahead and replaced it anyway.

Yes from what I've read and from what I can see they look replaceable. I did a quick look on google and didn't really find any replaceable cartridge bearing but they appear to be standard sealed bearings. Let's be honest though at this price you would probably be better off just replacing the pedals.

I see no ball bearings anywhere on my slide. They don't appear to be needed, but may be an addition on later models.

no these are not sealed motors,the moisture in a crawl space would damage these units

No, it does not. Only the output seal, metal clips for pump, and snapring access plug. No bearings or bushings.

They can handle the load, but you should get something where the bearings are sealed in better.

This is an 8 pack of bearings, but I do recommend these, they can get jammed but they are very easy to get unnamed without a cleaning kit

Yes it does. These are good bearings, too. Put mine on several years ago, still silent. 513121 is the part number though.

They have sealed bearings, run quite smoothly, i believe they are made by Formula. I have not yet used these wheels but had some Formula hubs in the past and had no problems with them. They see quite well made for the price.Sorry. can`t be more specific about the bearings without opening the hubs. For the price and look of the wheelset i am not worried, heard about spokes being too short on them.
