Optimised load spreading due to angular contact: the 71806 LLB bearing by Enduro Bearings

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. These bearings are engineered with a nylon retainer which diminishes rolling resistance and dual lip seals ensuring longer bearing life.
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.

- balls that roll on 15 degrees angular contact
- ranked ABEC 5 by Annular Bearing Engineer's Committee for manufacturing tolerances and noise testing
- grade 5 chromium steel balls = 5/1,000,000" tolerance of sphericity
- 52100 high carbon chromium alloy races with heat treatment followed by triple cryogenic treatment (310° Fahrenheit (-190° C)), hardened to at least Rockwell HRC 62, polished to a mirror finish for precision and noiseless movement
- LLB: most popular seal type, Nitrile material rubber with a steel insert; groove in the inner race where the seal can rotate (labyrinth seal), two razor thin sealing lips: the outside lip keeps the water and contaminates out, while the inner seal retains the grease
- filled 90 % with high pressure water proof grease
- load side on red seal side; 5-10 lbs preload required
