Disc springs Din 2093 Belleville washers Din 6796
Disc Springs, also known as Din 2093 spring washers or Disc Springs, are conical washers that offer an elastic proportional force to the deformation which they are subjected in the same axial direction. They are able to be used stacked so that allows us to adapt them to our needs. Related to the theoretical values, they are extremely precise pieces. They are designed to support a high number of cycles. Their fundamental characteristic is that you can obtain large values of force in small spaces. Its manufacturing procedures are defined by DIN 2093.
Belleville Din 6796 washers or pressure washers, have as a function to avoid the loss of preload between a screw and a nut or in any other type of union that allows its placement, by applying a permanent pressure on both. They ensure that the subject parts remain fixed despite vibrations or other forms of relaxation that can appear with the passage of time. Although its appearance is very similar to the disc springs, its characteristics are very different because they are not prepared for dynamic work. Its manufacturing procedures are defined by DIN 6796.
The product range is complemented by disc springs for ball bearings or ball bearing disc springs. These springs are designed to act as retainer of the ball bearings. Its function is to absorb the vibrations of the bearing (noise reduction). Its function is also to compensate the thermal expansions of the assembly during its operation without producing a variation of the recommended axial load indicated by the bearing manufacturer. There are two types of washers: slotted and plain.
