Bont partnered with Jesa for our high end bearings. 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.

For Bont’s inline racing application, 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. In addition, light weight plastic cages also create lower resistance. 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.
The inline market has been flooded with cheap ceramics bearings which have really given many skaters a bad opinion about ceramics in general. To be quite frank, many ceramics on the market are made with very poor tolerances and are slower than a typical ABEC 5 steel bearing. Bont ceramics are made in Switzerland. They have extremely precise balls. The ceramic balls not only generate less heat but offer considerable weight and friction benefits.
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.
Jesa increased the radial clearance providing slightly less ‘total contract ball patches’, which reduces drag. The bearings are made with 'Swiss Precision'.
Each bearing is individually tested to make sure it performs at Jesa's high standards.
Bont ABEC 5 bearings have been designed for the elite racer. They have double shields to keep the dust and dirt out and the shield can easily be removed for cleaning. We sell the bearings lubricated with a light racing oil. This means you don't have to clean our all the thick oil that you find in other bearings. The bearing has an exceptionally low rolling resistance for maximum speed!
