CHACB3645SS Enduro Hybrid Ceramic, Angular Contact, Bicycle Headset Bearing
Bicycle Hybrid Ceramic Headset Bearing
Enduro Bearings are quality bearings manufactured specifically for cycling - certain applications require specific materials, greases, and sealing arrangements. Enduro has it covered for environments and disciplines.
Angular Conatct Bearings
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.
Ceramic Hybrid
Ceramic bearings are not only here to stay, they are now the standard, period. When carbon fiber was first introduced, there were many riders still on steel bikes in the Tour de France, but now every racing bike is made of carbon fiber. This is the case for ceramic bearings, and the CH bearings are an excellent choice for entry into the technology. ABEC-5 tolerances and LLB seals with Graphite Nylon retainers are premium features that are not available on our competitor’s ceramic hybrid bearings at two or even five times the cost. Oversized Silicon Nitride Grade 5 balls and cryogenic treatment of the ABEC-5 races ensure long lasting, smooth rolling bearings at great value
- LLB - Is a double lip seal making light contact, and also rides in a groove making a labrinth seal (reducing friction for less rolling resistance whilst maintaining a good seal, preventing contaminating particles entering the raceways)
- Red seal indicates preload side - 5-10 lbs of preload required
- Black Seal indicates side to go against frame
- 15 Degree Contact Angle
Silicone Nitride Balls Si3N4
High precision balls lighter than steel, faster rolling, smoother,harder and rounder - What more could you want!.
Stainless Steel 440C raceways
High precision balls are within 5/1,000,000″ round. These are military level specification, used for precision equipment. R-64 hardness, of the highest grade
The ABEC 5 Standard
To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.
Graphite/Nylon Ball Retainers
Nylon with graphite retainers are virtually frictionless while providing constant lubrication.
