Optimised force absorption through helix angle: 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. 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.
In order to meet the ABEC 5 standard, a bearing must meet extremely high requirements for the roundness of the balls, tolerances of the inner and outer diameters, alignment of the running surfaces and low noise.
