Improve your acceleration. Only 4g per bearing. Being small in size, the 167 bearing offers the highest acceleration of any bearing on the market. Exactly what you need in Derby. It is also the lightest bearing on the market which also helps with acceleration. The bearing has double shields to stop dirt getting in and the bearings fits 7mm axles. Upgrade your bearings to the new 167 bearing from Bont. Patent Pending.

The 167 bearings weigh just 4 grams each or one third of a normal skate bearing which can lighten each skate by 64 grams.
Derby is all about acceleration. Every time you take off or sprint it takes energy. Smaller bearings take less energy to get up to speed and combined with the weight advantage your ability to accelerate and sprint will improve with 167 bearings.
Bont partnered with Jesa for the 167 bearing project. Jesa is the largest specialty bearing manufacturer in Switzerland and was established in 1969. Jesa is renowned for providing solutions for some of the most difficult applications, with its ‘clean sheet’ approach to each project. Jesa don’t make any standard bearings, they make specialty bearings for each customer’s application.
To clean your Bont 167 bearings you can use a Bont Electronic Bearing cleaner which spins the bearing to 12600 RPM to clean out every last bit of dirt and grime. You can also slide the bearings onto the end of a coat hanger and shake them up and down in a container filled with cleaning solution.
For the 167 bearing, Jesa has produced a bearing with the lowest friction on the market. They made the bearing with an exceptionally fine polished surface finish on the bearing tracks and incredibly precise balls. The better the finish is on the bearing, the less resulting drag. The less energy spent making the bearing roll, the more energy converted into speed.
Under load and at speed, bearings warp. Cheaper bearings tend to be made from soft steel which tend to warp a lot. This warping slows the bearings down. Bont Jesa bearings are made from high grade hardened steel which work to keep the bearing as round as possible. This means that the Bont Jesa bearing don't slow down as much from warping as most bearings do.
Jesa increased the radial clearance providing slightly less ‘total contract ball patches’, which reduces drag. The bearings are made with 'Swiss Precision'.
Most bearings are quickly polished in one direction to remove any metal fragments left behind in the manufacturing process. Bont Jesa bearings are finely polished in both directions to ensure the balls roll with the least amount of friction possible.
