I am tearing up bearings running street wheels on 10mm axles. I am having bearings wear out every 50-100 miles (grinding feeling when rotating and or high rolling resistance). My boards with 8mm bearings are much more resilient. Are others having issues 10mm bearings and what bearings are others running?
I am 160lbs, running a Onsra Black Carve 3 (BC3), and use Momentum Hollow Wheels Pro.
I have been using Fast Eddy 10x22x7 Rubber Sealed Bearing 6900/W7-2RS
I have found 10mm ceramic bearings but they are $10 each bearing!
Oh, I didn’t catch the outside diameter of the bearings you posted being larger. I think the small bearing is part of the problem of why I am tearing up the bearings; the bearing area has to be a lot smaller to fit street 22mm bearing size wheels on a 10mm axle. Or maybe if others are not having an issue I got a bad batch as they have all been from one order from FastEddy and have not gone through all of them to have to reorder.
Curious if the hallow wheels put extra lateral load on them. Or if the bearing seats are spaced a little further out than the standard 10mm.
If you have any resistance when fully tightened, then your axel isnt fully stacked, which points to bearing seat distance being off. Adding a speed ring innwith the 10mm spacer can cure this if thats the issue.
Make sure the nut and spacer isn’t touching the rubber seal when tightened. If so, add a speed ring to give clearance.
Should be hanger wall>speed ring>bearing>spacer>bearing>speed ring>nut
Also make sure there is complete contact between the bearing and the spacer. Add speed rings to fill whatever gaps.
I love built-in bearings since you never have to worry about spacers and speed rings but they are usually only available for standard 8mm 608’s sadly. Would love to see a push for zealous to produce a built-in 10mm bearing for the esk8 community. I’d finally make the switch to using 10mm axels if those ever became a thing.
