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.

not tight around your legs
Nice socks. They are thin and light weight so they are ideal to wear with snug fitting shoes. They have a nice cable style design to dress them up. I have been wearing a pair all day, and they do not dig into my legs at all. Love that. I have not washed them, but I see no reason why they would not wash up well in cold water and a low dry temperature. The price is great so give them a try.

Nice ruffle socks
First of all, I like the thickness of these ruffle socks. They are not too heavy nor too thin, making them ideal for all seasons wearing. The ruffle edges make the socks unique and beautiful. The quality feels quite good. I like the socks in six different color, all of them are beautiful.

Cute, very breathable material
These socks are super cute and comfy. I love the material-- it's light and very breathable. The ruffles are so cute. I think these socks work great with ankle-high boots or chunky sneakers.

Enables the person to move around while wearing.
These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.
