Ball Bearing Preload Disc Springs

The Ball Bearing Disc Springs are available in two different styles:plain and slotted.

Ball-bearing Pre-load Disc Springs are especially designed for use with radial ball bearings and maintain positioning accuracy of the bearing with no end play. These Springs minimise vibration and shaft deflection. Proper pre-loading will increase bearing rigidity and help eliminate excessive running noise.

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

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
