Ball Bearing Disc Springs (K springs)
The Ball Bearing Disc Springs are available in two different styles:
Plain Ball Bearing Disc Springs:
Disc springs with high force, low deflection and pronounced regressive spring characteristics are for backlash compensation, silencing and protection of ball bearings.
The regressive characteristic (flat curve in working range) has the advantage that the pre-load variation changes little within a wide range of deflection.Outside diameters OD ranging from 9.8 - 358mm (0.386" - 14.1")
Slotted Ball Bearing Disc Springs:
Disc springs with low force and large deflection characteristic are increasingly required for use with small size ball bearings.Outside diameters OD ranging from 9.8 - 94.5mm (0.386" - 3.72")
The Ball Bearing Disc Springs are referenced by the Ball Bearing Designation Number in our documentation for convenient selection.
In cases where higher spring forces are required, the Ball Bearing Disc Springs can be stacked in parallel for corresponding factors of two or more.
