AKA Slotted Bearing Preload Washers
30 different sizes in stock from 9.8mm up to 94.5mm outside diameter
This range of bearing preload disc springs (washers) have a slotted inside profile which gives a different force/deflection profile to plain type preload disc springs.
These preload disc springs are manufactured from CK75 Carbon Steel (DIN 1.1248) with a zinc phosphate and oiled finish providing a good selection of dimensions to suit most standard roller bearings.
Slotted type 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.
