Enduro ABEC-3 Bearings
Angular Contact BB Repair Pack for the following Wheels Mfg SRAM/GXP bottom brackets:
- EBB Eccentric
- BSA Threaded Road
- BSA Threaded MTB
GRADE 10 CHROMIUM STEEL BALLS:
High precision balls are within 10/1,000,000″ round, twice as round as the industry standard, at it’s highest level.
52100 HIGH CARBON CHROMIUM ALLOY RACES:
Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-3 precision and noiseless movement.
Riveted Steel Retainer for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance
Enduro Angular Contact Sealed Bearings:
Enduro Angular Contact bearings are specifically designed for hubs and bottom brackets. In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact 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, to giving a more stable wheel, making it easier to adjust disc brakes, while still spinning freely
Grade 5 Chromium Steel Balls:
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.
52100 High Carbon Chromium Alloy Races:
Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-5 precision and noiseless movement.
Graphite/Nylon Ball Retainers:
Nylon with graphite retainers are virtually frictionless while providing constant lubrication.
The bearing seals are dual lip, groove type seals rather than standard 2RS types that other manufacturers use; one lip to keep the dirt out and the other to keep the 90% grease fill inside. Bearings are filled both sides with Mobilgrease XHP 222 mineral oil based grease for the best protection and long lasting set up. Another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration.
Because of the internal ball path design, all of the balls are engaged 100% of the time lending even maximum support through the entire pedal stroke. Filled with Rheolube special synthetic grease formulated in the USA, the balls are micro-coated with long lasting protection from friction. "LLB" dual lip groove seals and another external seal with dual lips on both sides and made from the best Silicone material guards from water and dirt penetration. We back them up with a 1 year warranty.*
