Does this bearing movement look okay?

How-Tos & Esk8 mechanics

Not sure if this is the right section to ask this.

I just got Newbee Pentagram hubs and there are 2 potential issues I see with them.

  1. Bearings dont exactly press fit into them so sometimes the outer race spins in the hub.

  2. 22.2mm bearing spacers seem to allow the wheel to move back and forth about 0.2mm or so on the bearings, causing a clicking sound when it moves.

Is this something I should worry about or try to fix? Just knowing the wiggle is there will drive me crazy.
I suppose I could get the bearing spacers machined slightly down to 22.00mm in order to prevent the movement of the wheels independent of the bearings. Not sure if that would stop the hub and bearing outer race spinning independently of each other though.

Here’s a video showing the bearing movement.

Huh. That might be fine. I would fix it though.

I would be less worried with plastic hubs, but with metal you will wear it out over time.

Im looking into some type of loctite bearing retaining compound for the races spinning. I just dont want them to be permenantly adhered to the hubs lol. May take the spacers to a machine shop…

Glue the fuckers in with bearing retaining compound?

Very fine sandpaper and a flat table.

Any experience yourself? Im looking at 641, 660, 620, etc…

I got some infinity hubs and had some loose tolerances at the bearing adapters. Used a loctite compound. Can’t remember. Will find some pics. Hang on.

So mine was an adapter not a bearing, but I used 680. Held solid now :joy:

I think 680 is best of retaining compounds (aka not threadlocker), covers a large range of esk8 needs.

Instead of a huge bottle that’s a bit expensive, you can get a small bottle on eBay that will essentially last a single diy esk8r forever.

Yah ive got 680. Its strong as hell. I guess ill have to heat the bearings with a torch when i want to remove them :laughing:.

I did manage to sand 1 bearing spacer down to 22.00mm and the clicking is gone now. Just 3 more to go…:tired_face:

Actually im gonna get 609…its medium strength rather than high strength. Should be easier to remove the bearings later.

Edit: ordered 641 instead. Its designed specifically for bearings that you want to be able to easily remove later without any issues. “Controlled strength for ease of disassembly.”

If it is anything like their other products that claim to be removable, then it should be more than strong enough to hold it in place. Don’t expect the bearing to be easy to remove though :rofl: Learned that the hard way with their blue thread locker that claimed to be removable with hand tools. The bolts were eventually removed but not without almost stripping them first heat was not used since I did not know that would help since the packaging didn’t mention it at all

Yah thats why i am being patient and getting their weakest retaining compound rather than welding the bearings in with the 680 that i already have :laughing:. Although ive never had any issues with blue threadlocker. Its always been really easy to unscrew blue loctited bolts for me to the point that ive considered using red. It can depend on the diameter of the bolt of course too.

It’s highly material dependent too. Rule of thumb is that loctites on aluminum are 1/2 the strength they are on steel.

I believe they were stainless steel bolts since I would have bought the weather resistant ones from Lowes which is their more specialized stainless steel line. It is slightly more expensive than the normal stainless steel options and I honestly have no idea if it makes a difference :rofl: The price difference is so minimal that it is worth paying the extra amount just in case.

Past me didn’t think to look for the proper size locking nuts and just used normal nuts so I added a ton of locktite to make sure they stayed on. Had I realized they sold the right size nylon lock nuts I would have bought them but they like to hide them in the drawers so I didn’t know they sold them. :weary:

It was for this which I was able to put together thanks to the Lowe’s employees helping me find what could work.
