Preload Disc Springs: Slotted Type

Slotted Type

Pre-Load Disc Springs are designed for use with radial ball-bearings. They assist in maintaining positioning accuracy of the bearing, with no end play. They also minimise vibration and shaft deflections. Proper pre-loading will increase bearing rigidity, and eliminate excessive running noise.

Note: The Pre-Load types of Disc Spring may also prove useful in other applications, e.g. light duty linkages or mechanisms, particularly in view of the relatively low forces when compared with other ranges of Disc Springs. However, caution should be exercised when considering columns of these springs as a ratio of cone height / thickness in excess of 1.50 may lead to inversion of springs and column collapse.
