Grinding spindle bearings
Apr 07, 2007· With angular contact ball bearings, preload does wonders for stiffening up the spindle against chatter and all sorts of deflection. it takes up the "freeplay" and runs the balls under some initial load so that there is a restoring force to bring the spindle back to center.

Angular contact ball bearings
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis ().

Bearing Dictionary
Friedrich Fischer's idea from the year 1883 for milling and grinding balls of equal size and exact roundness by means of a suitable production machine formed the foundation for creation of an independent bearing industry. A patent on ball bearings, reportedly the first, was awarded to Jules Suriray, a Parisian bicycle mechanic, on 3 August 1869.

Assuming this is a standard derailleurstyle bike, the grinding noise, if not due to some external rubbing against the frame (which should be visible) would be due to the bearings going bad. If the bearings are of the loose ball/cone/cup variety then this can be cheaply repaired, if not too far gone.
