Flat washers are generally used in connectors where one is soft and the other is hard and brittle. Their main function is to increase the contact area, disperse pressure, and prevent the soft material from being crushed. The basic function of the spring washer is to apply force to the nut after tightening it, increasing the friction force between the nut and the bolt! The material is 65Mn (spring steel), with a heat treatment hardness of HRC44-51HRC, and has undergone surface oxidation treatment.

1. WG type waveform washer: WG type waveform washer is an open elastic washer that can usually be installed in a small space, such as applying pre-stress to bearings to reduce noise during bearing operation and improve the accuracy and smoothness of bearing operation. In addition, there are also a large number of application materials in electronics and appliances, such as carbon steel, stainless steel, copper alloy, etc.

2. WL type waveform washer: WL type waveform washer is a lap type elastic washer that can usually be installed in a small space, such as applying pre-stress to bearings to reduce noise during bearing operation and improve the accuracy and smoothness of bearing operation. In addition, it has a large number of applications in electronics and appliances. Materials include carbon steel, stainless steel, copper alloy, etc. 3. WN type waveform washer: The WN type waveform washer is a multi-layer overlapping elastic washer. Compared with the WL type, this series is composed of multiple layers of materials, so the K-value curve under the same compression stroke is smoother than the WL type. It is suitable for situations where the elastic force is large and the elastic force release throughout the entire working stroke is required to be more uniform The materials used include carbon steel, stainless steel, copper alloy, etc.
