JESA 608 Black Series Roller Skate BearingsAre you looking to buy the fastest and best roller skate bearing on the market? You have found them.

Not only did we use aerospace grade steel for the outer race, but we also double polished the outer and inner race to provide the least amount of friction possible.

Are you looking to buy the fastest and best roller skate bearing on the market? You have found them. We built this bearing from scratch with JESA of Switzerland. Not only did we use aerospace-grade steel for the outer race, but we also double-polished the outer and inner race to provide the least amount of friction possible. The balls go through a number of stages of polishing, far more than any standard ABEC 5, 7, or 9 bearing to make sure that they are as round as possible. To help reduce drag, Jesa increased the radial clearance providing slightly fewer total contact ball patches. Additionally, the lightweight plastic cages allow for lower rolling resistance. Finally, we use a special lightweight racing oil from Germany called Kluber oil to top the bearing off. The result is the fastest steel skate bearing on the market. 

  • Bearing type: 608 8mm 
  • Dimension: 8mm core, 22 outer diameter, 7mm width
  • Protection: 1-Z shield
  • Cage: TN9-plastic cage
  • Ball complement: 7 pieces
  • Ball material: High-grade steel

Pack of 16 pieces.

Spaces not included.

To ensure all of this hard work in creating the bearing actually works in practice, our professional inline skating team which includes a number of world champions tests the bearings in real work conditions to confirm that these are the best roller skate bearings. We complete back to back lap time comparisons as well as roll tests. Our roller derby team tests the strength of the bearings in bouts. Our testing confirms that there is no faster steel bearing than the Bont 608 steel roller skate bearing.

I'm not sure what they're selling.
Gimbal extractor works. One of these guys needs to come down here and show me how the installer works. There is a driver for the bearing with pin but the driver rod itself has no hole like shown in the picture. How do you miss that?

Good value, very useful for go kart wiring
Size: 100ft, Style: 6C-18AWG
It's a good spool to have around to wire lights and things on the go karts. Also came in handy when I had to patch a bit of melted wire harness on the tail of the old Dodge.

Beware! Very thick wire
Size: 50ft, Style: 6C-18AWG
I'm not going to ding the product, because it's totally what it says it is. I didn't look at the diagrams to see that this wire is 10mm wide. Almost half an inch. Waaaay to thick for the project I needed it for.

Fair product
Size: 30ft, Style: 6C-18AWG
nice product good price, the only issue I had was the sleeve was very loose on the wires so doesn't really hold the wires in place.

Fantastic to do 1 run and power multiple loads
Size: 30ft, Style: 6C-18AWG
Great for wiring up multiple loads. In my case multiple lighting with different switches so that I can turn them on independently from one another.
