Enduro Bearings Angular Contact Ball Bearing 6808 40 mm x 52 mm x 7 mm for Headset

The 6808 2RS CC Bearing by Enduro Bearings - Optimised force absorption through helix angle

In standard radial bearings, only 3 or 4 balls make contact during the load at any given time. Inside of Enduro Bearings' Angular Contact (A/C) bearings, ALL balls are engaged so that they can distribute force over a larger surface area. This reduces friction and minimizes wear. These bearings have a nylon ball cage for the lowest possible running resistance and a double rubber sealing system, which extends the service life.

Features:

• angular contact ball bearings with 45° angle
• chrome steel balls 5th degree = roundness is 5/1,000,000"
• race grooves made of carbon-chrome steel alloy, heat and triple cold treated (down to -190° C), minimum hardness Rockwell HRC 62, polished
• LLB: widely used seal type made of nitrile rubber with steel insert, in a groove in the inner race (labyrinth bearing), two super thin sealing lips; the outer one keeps out water and contaminants, the inner one retains grease
• 90% filled with waterproof high-pressure grease
• black oxide (BO) for higher corrosion resistance and hardness
