Wave Washer (Bearing Washers)DIN : 137
IIS Manufactures and Stocks all types of Wave Washers as per DIN 137 B. The Wave Washers are made from Prime Quality Spring Steel. Stainless Steel and Copper are also available in Standard Sizes. Wave Washers are wavy Metal Washers designed to offer a compensating spring force and maintain a load or take up shock. These are the disks of irregular shape formed in such a way that when loaded it deflects acts, like a spring and provides a preload between two surfaces. Wave Washers are very useful for limited radial space and moderate thrust load eg. Axial Loading of Ball Bearing.
The number of Waves can be Two, Three or more. The spring rate is proportional to the number of waves raised to the fourth power.
Wave Washers are generally preferred as cushion / cushion spacers between parts on shafts or to take up the probable deviation in assembled parts. These are positioned underneath a Nut, an Axle Bearing, or a Joint, to reduce friction, avoid leekage, isolate, stop loosening or distribute pressure.
