With dual-lip labyrinth seals keep dirt out and grease in, even under extreme conditions. Packed from the factory with the highest quality Rock ‘N’ Roll grease.
ABEC 5 is a standard to which each bearing must pass many tests in order to meet the scheduled requirements including noise testing at high RPM, extremely tight tolerances for the internal diameter, outer diameter, roundness of ball, trueness of races, and surface finish of
all of the above. A much higher standard than ABEC 3, even though only 2 digits difference in name.
Enduro is the first to produce a truly sealed Full Ceramic Bearing. The balls and the races are made from Si3N4 (Silicon Nitride) material which is the hardest, most resilient and the lightest weight material a bearing can be made from. A standard steel type sealed bearing design would be an inferior way to utilize this material. However, through a new design of the race assembly, we are able to seal these bearings on the side facing the elements, while shielding the internal side with the PTFE retainer. The seal is also made from Silicone material which is the lowest friction and the superior material a seal can be made from. These seals are also easily removable and replaceable. The level of precision for these bearings are ABEC 5 and the Si3N4 balls are Grade 5 giving an almost zero level of friction from your bearings. We use finally a special grease to lubricate the bearing after it has been installed
