BONT 688 Bearings

Bont partnered with Jesa for this 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.

  • This bearing has an exceptionally fine polished bearing track surface and incredibly precise balls.
  • Light weight plastic cages for lower rolling resistance.
  • The steel is extremely strong which helps the bearing keep its shape when under load.
  • Jesa increased the radial clearance providing slightly less 'total contact patches', reducing drag.
  • Made in Switzerland.

Bont bearing adapters can be used, if you want to run a mini bearing in a wheel that was made for a larger 608 bearing. The benefit of using a mini bearing and an adapter rather than a 608 bearing is that you can create a much lighter set up with better acceleration.

This product requires cylinder spaces, not the normal self centering spacers.
