ACBCH 3645 Enduro Hybrid Ceramic Angular Contact Bike Headset Bearing

Ceramic Hybrid combines the chromium steel races found in Enduro’s ABEC 5 range with Grade 5 ceramic (Silicon Nitride – Si3n4) balls found in Zero Ceramic bearings. This combination creates a lighter, more efficient and more affordable ceramic bearing, perfect for use in hubs or bottom brackets. The low contact LLB seals provide protection from water or dirt ingress, but without causing any friction or drag

Enduro produce a line of Angular Contact (A/C) cartridge bearings specifically designed for hubs. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear. Wheel play can be adjusted out of the hub providing a more stable wheel, and making it easier to adjust disc brakes while still spinning freely
