The relationship amongst wheel hubs, bearings, and bearing spacers happen to be a subject with considerably confusion. Last year I did an article on bearing spacers, but didn’t go into the sizing, so I am hoping to shed some light with the following photos and descriptions.
Bearing Spacers are designed to match the length of space between your 2 bearings when mounted inside wheels. Once the wheels are mounted, and the axle nut is snug, then your bearings will be appropriately spaced, thus delivering optimal velocity and more durable bearings.
Bearing spacers are available in 4 different sizes. From left to correct, they’re 8mm x 8mm, 8mm x 10mm, 10mm x 8mm, and 10mm x 10mm. I know, this is very confusing, but all you need to know would be that the initially quantity relates to the axle diameter on the vans and the second variety pertains to the spacing employed inside of the wheel hub. Most of the time you will employ the 8mm x 10mm bearing spacers.
We begin by looking at the initially amount, the one which relates to the axle diameter. There’s twoby far the most common size, and 10mm axles are typically used for racing boards only. At the moment, The Longboard Store only gives 10mm axles about the Bear Trucks.
The 2nd quantity on that bearing spacer relates to the spacing utilized in the wheel hub. See the middle of the wheel over? A bearing is pushed into that hub from both sides till they touch that that tab within the really middle, developing a space among both bearings. Therefore the wheel assembly will perform correctly and keep going longer, we like to fill that space having a metal spacer that won’t be squished when the wheel assembly is tightened. So, that space is going to be either 8mm vast or 10mm vast, the 2nd range about the bearing spacer. The most typical wheel hub spacing will be 10m.
The bearing on the left shows a smaller inside diameter of 8mm, which would be used on 8mm axle vans. The right bearing includes a bigger inside of diameter of 10mm, and it is utilized on 10mm axle vehicles. Again, an 8mm bearing and truck is probably the most common.
We rely on them on each total longboard we develop, but are you aware why?
We begin with pace washers. The castings where the steel axle and aluminum hanger meet might have flashing, to assist align and reduce friction, we use pace washers. These are typically supplied by the18 wheeler manufacturer. We also offer some premium velocity washers with increased surface area.
Bearing Spacers are designed to match the distance of space between the 2 bearings when installed inside of wheels. Once the wheels are installed, and also the axle nut is snug, then your bearings is going to be effectively spaced, therefore providing optimum pace at more durable bearings.
