With dimensions to suit most standard roller bearings (radial ball bearings), this range of plain bearing preload disc springs are manufactured from CK75 Carbon Steel (DIN 1.1248) with a zinc phosphate and oiled finish.
The preload disc springs (or washers) assist in maintaining positioning accuracy of the bearing (with no end play) and also minimise vibration and shaft deflections. Correct preloading will also increase bearing rigidity and negate excessive running noise.
Preload disc springs can also be useful in other applications. The relatively low forces of the preloaded disc springs means they could act as light duty linkages or mechanisms.
A note of caution however when considering columns of these disc springs. A ratio of cone height/thickness in excess of 1.50 could cause springs to invert and the column to collapse.
